With the rise of data-driven recruitment, it is imperative for each recruitment tool, including candidate sourcing and screening tools, to integrate with Applicant Tracking Systems (ATS) for enabling centralized data management for end users. 

However, there are hundreds of ATS applications available in the market today. To integrate with each one of these applications with different ATS APIs is next to impossible. 

That is why more and more recruitment tools are looking for a better (and faster) way to scale their ATS integrations. Unified ATS APIs are one such cost-effective solution that can cut down your integration building and maintenance time by 80%. 

Before moving on to how companies can leverage unified ATS API to streamline candidate sourcing and screening, let’s look at the workflow and how ATS API helps. 

Candidate sourcing and screening workflow

Here’s a quick snapshot of the candidate sourcing and screening workflow: 

1) Job posting/ data entry from job boards

Posting job requirements/ details about open positions to create widespread outreach about the roles you are hiring for. 

2) Candidate sourcing from different platforms/ referrals

Collecting and fetching candidate profiles/ resumes from different platforms—job sites, social media, referrals—to create a pool of potential candidates for the open positions.

3) Resume parsing 

Taking out all relevant data—skills, relevant experience, expected salary, etc. —from a candidate’s resume and updating it based on the company’s requirement in a specific format.

4) Profile screening

Eliminating profiles which are not relevant for the role by mapping profiles to the job requirements.  

5) Background checks 

Conducting a preliminary check to ensure there are no immediate red flags. 

6) Assessment, testing, interviews

Setting up and administering assessments, setting up interviews to ensure role suitability and collating evaluation for final decision making. 

7) Selection 

Sharing feedback and evaluation, communicating decisions to the candidates and continuing the process in case the position doesn’t close. 

How ATS API helps streamline candidate sourcing and screening

Here are some of the top use cases of how ATS API can help streamline candidate sourcing and screening.

Centralized data management and communication

All candidate details from all job boards and portals can be automatically collected and stored at one centralized place for communication and processing and future leverage. 

Automated profile import

ATS APIs ensure real time, automated candidate profile import, reducing manual data entry errors and risk of duplication. 

Customize screening workflows 

ATS APIs can help automate screening workflows by automating resume parsing and screening as well as ensuring that once a step like background checks is complete, assessments and then interview set up are triggered automatically. 

Automated candidate updates within the ATS in real time

ATS APIs facilitate real time data sync and event-based triggers between different applications to ensure that all candidate information available with the company is always up to date and all application updates are captured ASAP.  

Candidate engagement data, insights and patterns using ATS data

ATS APIs help analyze and draw insights from ATS engagement data — like application rate, response to job postings, interview scheduling — to finetune future screening.

Integrations with assessment, interview scheduling and onboarding applications

ATS API can further integrate with other assessment, interview scheduling and onboarding applications enabling faster movement of candidates across different  recruitment stages. 

Personalized outreach based on historical ATS data

ATS API integrations can help companies with automated, personalized and targeted outreach and candidate communication to improve candidate engagement, improve hiring efficiency and facilitate better employer branding. 

‍

Undoubtedly, using ATS API integration can effectively streamline the candidate sourcing and screening process by automating several parts of the way. However, there are several roadblocks to integrating ATS APIs at scale because of which companies refrain from leveraging the benefits that come along. Try our ROI calculator to see how much building integrations in-house can he.

In the next section we will discuss how to solve the common challenges for SaaS products trying to scale and accelerate their ATS integration strategy.

Addressing challenges of ATS API integration with Unified API

Let's discuss how the roadblocks can be removed with unified ATS API: just one API for all ATS integrations. Learn more about unified APIs here

Challenge 1: Loss of data during data transformation 

When data is being exchanged between different ATS applications and your system, it needs to be normalized and transformed. Since the same details from different applications can have different fields and nuances, chances are if not normalized well, you will end up losing critical data which may not be mapped to specific fields between systems. 

This will hamper centralized data storage, initiate duplication and require manual mapping not to mention screening workflow disruption. At the same time, normalizing each data field from each different API requires developers to understand the nuances of each API. This is a time and resource intensive process and can take months of developer time.

How unified ATS API solves this: One data model to prevent data loss

Unified APIs like Knit help companies normalize different ATS data by mapping different data schemas from different applications into a single, unified data model for all ATS APIs. Data normalization takes place in real time and is almost 10X faster, enabling companies to save tech bandwidth and skip the complex processes that might lead to data loss due to poor mapping.

Bonus: Knit also offers an custom data fields for data that is not included in the unified model, but you may need for your specific use case. It also allows you to to request data directly from the source app via its Passthrough Request feature. Learn more

Challenge 2: Delayed recruitment due to inability of real-time sync and bulk transfers

Second, some ATS API integration has a polling infrastructure which requires recruiters to manually request candidate data from time to time. This lack of automated data updation in real time can lead to delayed sourcing and screening of applicants, delaying the entire recruitment process. This can negatively impact the efficiency that is expected from ATS integration. 

Furthermore, Most ATS platforms receive 1000s of applications in a matter of a few minutes. The data load for transfer can be exceptionally high at times, especially when a new role is posted or there is any update.

As your number of integrated platforms increases, managing such bulk data transfers efficiently as well as eliminating delays becomes a huge challenge for engineering teams with limited bandwidth

How unified ATS API solves this: Sync data in real-time irrespective of data load/ volume

Knit as a unified ATS API ensures that you don’t lose out on even one candidate application or be delayed in receiving them. To achieve this, Knit works on a  webhooks based system with event-based triggers. As soon as an event happens, data syncs automatically via webhooks. 

Read: How webhooks work and how to register one?

Knit manages all the heavy lifting of polling data from ATS apps, dealing with different API calls, rate limits, formats etc. It automatically retrieves new applications from all connected ATS platforms, eliminating the need to make API calls or manual data syncs for candidate sourcing and screening. 

At the same time, Knit comes with retry and resiliency guarantees to ensure that no application is missed irrespective of the data load. Thus, handling data at scale. 

This ensures that recruiters get access to all candidate data in real time to fill positions faster with automated alerts as and when new applications are retrieved for screening. 

Challenge 3: Compliance and candidate privacy concerns

Since the ATS and other connected platforms have access to sensitive data, protecting candidate data from attacks, ensuring constant monitoring and right permission/ access is crucial yet challenging to put in practice.

How unified ATS API solves this: Secure candidate data effectively

Knit unified ATS API enables companies to effectively secure the sensitive candidate data they have access to in multiple ways. 

• First, all data is doubly encrypted, both at rest and in transit. At the same time, all PII and user credentials are encrypted with an additional layer of application security. 

• Second, having an events-driven webhooks architecture, Knit is the only unified ATS API which does not store any copy of the customer data in its server. Thus, reducing changes of data misuse further. 

• Third, Knit is GDPR, SOC II and ISO27001 compliant to make sure all industry security standards are met. So, there’s one less thing for you to worry about.

Challenge 4: Long deployment duration and resource intensive maintenance

Finally, ATS API integration can be a long drawn process. It can take 2 weeks to 3 months and thousands of dollars to build integration with  just a single ATS provider. 

With different end points, data models, nuances, documentation etc. ATS API integration can be a long deployment project, diverting away engineering resources from core functions.

It’s not uncommon for companies to lose valuable deals due to this delay in setting up customer requested ATS integrations. 

Furthermore, the maintenance, documentation, monitoring as well as error handling further drains engineering bandwidth and resources. This can be a major deterrent for smaller companies that need to scale their integration stack to remain competitive.  

How unified ATS API solves this: Instant scalability

A unified ATS API like Knit allows you to connect with 30+ ATS platforms in one go helping you expand your integration stack overnight. 

All you have to do is embed Knit’s UI component into your frontend once. All heavy lifting of auth, endpoints, credential management, verification, token generations, etc. is then taken care of by Knit. 

Other benefits of using a Unified ATS API

Fortunately, companies can easily address the challenges mentioned above and streamline their candidate sourcing and screening process with a unified ATS API. Here are some of the top benefits you get with a unified ATS API:

Effective monitoring and logging for all APIs

Once you have scaled your integrations, it can be difficult to monitor the health of each integration and stay on top of user data and security threats. Unified API like Knit provides a detailed Logs and Issues dashboard i.e. a one page overview of all your integrations, webhooks and API calls. With smart filtering options for Logs and Issues,  Knit helps you get a quick glimpse of the API's status, extract historical data and take necessary action as needed.

Extensive range of Read and Write APIs

Along with Read APIs, Knit also provides a range of Write APIs for ATS integrations so that you can not only fetch data from the apps, you can also update the changes — updating candidate’s stage, rejecting an application etc. — directly into the ATS application's system. See docs

Save countless developer hours and cost

For an average SaaS company, each new integration takes about 6 weeks to 3 months to build and deploy. For maintenance, it takes minimum of 10 developer hours per week. Thus, building each new integration in-house can cost a SaaS business ~USD 15,000. Imagine doing that for 30+ integrations or 200!

On the other hand, by building and maintaining integrations for you, Knit can bring down your annual cost of integrations by as much as 20X. Calculate ROI yourself

In short, an API aggregator is non negotiable if you want to scale your ATS integration stack without compromising valuable in-house engineering bandwidth.

How to improve your screening workflow with Knit unified ATS API

Get Job details from different job boards

Fetch job IDs from your users Applicant Tracking Systems (ATS) using Knit’s job data models along with other necessary job information such as departments, offices, hiring managers etc.

Get applicant details

Use the job ID to fetch all and individual applicant details associated with the job posting. This would give you information about the candidate such as contact details, experience, links, location, experience, current stage etc. These data fields will help you screen the candidates in one easy step.

Complete screening activities

Next is where you take care of screening activities on your end after getting required candidate and job details. Based on your use case, you parse CVs, conduct background checks and/or administer assessment procedures.

Push back results into the ATS

Once you have your results, you can progmmatically push data back directly within the ATS system of your users using Knit’s write APIs to ensure a centralized, seamless user experience. For example, based on screening results, you can —

• Update candidate stage using <update stage> API See docs
• Match scores for CV parsing or add a quick tag to your applicant See docs
• Reject an application See docs and much more

Thus, Knit ensures that your entire screening process is smooth and requires minimum intervention.

In the world of APIs, it's not enough to implement security measures and then sit back, hoping everything stays safe. The digital landscape is dynamic, and threats are ever-evolving. 

Why do you need to monitor your APIs regularly

Real-time monitoring provides an extra layer of protection by actively watching API traffic for any anomalies or suspicious patterns.

For instance - 

• It can spot a sudden surge in requests from a single IP address, which could be a sign of a distributed denial-of-service (DDoS) attack. 
• It can also detect multiple failed login attempts in quick succession, indicating a potential brute-force attack. 

In both cases, real-time monitoring can trigger alerts or automated responses, helping you take immediate action to safeguard your API and data.

API Logging

Now, on similar lines, imagine having a detailed diary of every interaction and event within your home, from visitors to when and how they entered. Logging mechanisms in API security serve a similar purpose - they provide a detailed record of API activities, serving as a digital trail of events.

Logging is not just about compliance; it's about visibility and accountability. By implementing logging, you create a historical archive of who accessed your API, what they did, and when they did it. This not only helps you trace back and investigate incidents but also aids in understanding usage patterns and identifying potential vulnerabilities.

To ensure robust API security, your logging mechanisms should capture a wide range of information, including request and response data, user identities, IP addresses, timestamps, and error messages. This data can be invaluable for forensic analysis and incident response. 

API monitoring

Combining logging with real-time monitoring amplifies your security posture. When unusual or suspicious activities are detected in real-time, the corresponding log entries provide context and a historical perspective, making it easier to determine the extent and impact of a security breach.

Based on factors like performance monitoring, security, scalability, ease of use, and budget constraints, you can choose a suitable API monitoring and logging tool for your application.

In the modern application development and data integration world, APIs (Application Programming Interfaces) serve as the backbone for connecting various systems and enabling seamless data exchange. 

However, when working with APIs that return large datasets, efficient data retrieval becomes crucial for optimal performance and a smooth user experience. This is where API pagination comes into play.

In this article, we will discuss the best practices for implementing API pagination, ensuring that developers can handle large datasets effectively and deliver data in a manageable and efficient manner. (We have linked bite sized how-to guides on all API pagination FAQs you can think of in this article. Keep reading!)

But before we jump into the best practices, let’s go over what is API pagination and the standard pagination techniques used in the present day.

What is API Pagination

API pagination refers to a technique used in API design and development to retrieve large data sets in a structured and manageable manner. When an API endpoint returns a large amount of data, pagination allows the data to be divided into smaller, more manageable chunks or pages. 

Each page contains a limited number of records or entries. The API consumer or client can then request subsequent pages to retrieve additional data until the entire dataset has been retrieved.
Pagination typically involves the use of parameters, such as offset and limit or cursor-based tokens, to control the size and position of the data subset to be retrieved. 

These parameters determine the starting point and the number of records to include on each page.

Advantages of API Pagination

By implementing API pagination, developers as well as consumers can have the following advantages - 

1. Improved Performance

Retrieving and processing smaller chunks of data reduces the response time and improves the overall efficiency of API calls. It minimizes the load on servers, network bandwidth, and client-side applications.

2. Reduced Resource Usage 

Since pagination retrieves data in smaller subsets, it reduces the amount of memory, processing power, and bandwidth required on both the server and the client side. This efficient resource utilization can lead to cost savings and improved scalability.

3. Enhanced User Experience

Paginated APIs provide a better user experience by delivering data in manageable portions. Users can navigate through the data incrementally, accessing specific pages or requesting more data as needed. This approach enables smoother interactions, faster rendering of results, and easier navigation through large datasets.

4. Efficient Data Transfer

With pagination, only the necessary data is transferred over the network, reducing the amount of data transferred and improving network efficiency.

5. Scalability and Flexibility

Pagination allows APIs to handle large datasets without overwhelming system resources. It provides a scalable solution for working with ever-growing data volumes and enables efficient data retrieval across different use cases and devices.

6. Error Handling

With pagination, error handling becomes more manageable. If an error occurs during data retrieval, only the affected page needs to be reloaded or processed, rather than reloading the entire dataset. This helps isolate and address errors more effectively, ensuring smoother error recovery and system stability.

‍

Common examples of paginated APIs 

Some of the most common, practical examples of API pagination are: 

• Platforms like Twitter, Facebook, and Instagram often employ paginated APIs to retrieve posts, comments, or user profiles. 
• Online marketplaces such as Amazon, eBay, and Etsy utilize paginated APIs to retrieve product listings, search results, or user reviews.
• Banking or payment service providers often provide paginated APIs for retrieving transaction history, account statements, or customer data.
• Job search platforms like Indeed or LinkedIn Jobs offer paginated APIs for retrieving job listings based on various criteria such as location, industry, or keywords.

‍

API pagination techniques

There are several common API pagination techniques that developers employ to implement efficient data retrieval. Here are a few useful ones you must know:

1. Offset and limit pagination
2. Cursor-based pagination
3. Page-based pagination
4. Time-based pagination
5. Keyset pagination

Best practices for API pagination

When implementing API pagination in Python, there are several best practices to follow. For example,  

1. Use a common naming convention for pagination parameters

Adopt a consistent naming convention for pagination parameters, such as "offset" and "limit" or "page" and "size." This makes it easier for API consumers to understand and use your pagination system.

2. Always include pagination metadata in API responses

Provide metadata in the API responses to convey additional information about the pagination. 

This can include the total number of records, the current page, the number of pages, and links to the next and previous pages. This metadata helps API consumers navigate through the paginated data more effectively.

For example, here’s how the response of a paginated API should look like -

        
{
 "data": [
   {
     "id": 1,
     "title": "Post 1",
     "content": "Lorem ipsum dolor sit amet.",
     "category": "Technology"
   },
   {
     "id": 2,
     "title": "Post 2",
     "content": "Praesent fermentum orci in ipsum.",
     "category": "Sports"
   },
   {
     "id": 3,
     "title": "Post 3",
     "content": "Vestibulum ante ipsum primis in faucibus.",
     "category": "Fashion"
   }
 ],
 "pagination": {
   "total_records": 100,
   "current_page": 1,
   "total_pages": 10,
   "next_page": 2,
   "prev_page": null
 }
}
        
    

3. Determine an appropriate page size

Select an optimal page size that balances the amount of data returned per page. 

A smaller page size reduces the response payload and improves performance, while a larger page size reduces the number of requests required.

Determining an appropriate page size for a paginated API involves considering various factors, such as the nature of the data, performance considerations, and user experience. 

Here are some guidelines to help you determine the optimal page size.

4. Implement sorting and filtering options

Provide sorting and filtering parameters to allow API consumers to specify the order and subset of data they require. This enhances flexibility and enables users to retrieve targeted results efficiently. Here's an example of how you can implement sorting and filtering options in a paginated API using Python:

        
# Dummy data
products = [
    {"id": 1, "name": "Product A", "price": 10.0, "category": "Electronics"},
    {"id": 2, "name": "Product B", "price": 20.0, "category": "Clothing"},
    {"id": 3, "name": "Product C", "price": 15.0, "category": "Electronics"},
    {"id": 4, "name": "Product D", "price": 5.0, "category": "Clothing"},
    # Add more products as needed
]


@app.route('/products', methods=['GET'])
def get_products():
    # Pagination parameters
    page = int(request.args.get('page', 1))
    per_page = int(request.args.get('per_page', 10))


    # Sorting options
    sort_by = request.args.get('sort_by', 'id')
    sort_order = request.args.get('sort_order', 'asc')


    # Filtering options
    category = request.args.get('category')
    min_price = float(request.args.get('min_price', 0))
    max_price = float(request.args.get('max_price', float('inf')))


    # Apply filters
    filtered_products = filter(lambda p: p['price'] >= min_price and p['price'] <= max_price, products)
    if category:
        filtered_products = filter(lambda p: p['category'] == category, filtered_products)


    # Apply sorting
    sorted_products = sorted(filtered_products, key=lambda p: p[sort_by], reverse=sort_order.lower() == 'desc')


    # Paginate the results
    start_index = (page - 1) * per_page
    end_index = start_index + per_page
    paginated_products = sorted_products[start_index:end_index]


    return jsonify(paginated_products)

        
    

5. Preserve pagination stability

Ensure that the pagination remains stable and consistent between requests. Newly added or deleted records should not affect the order or positioning of existing records during pagination. This ensures that users can navigate through the data without encountering unexpected changes.

6. Handle edge cases and error conditions

Account for edge cases such as reaching the end of the dataset, handling invalid or out-of-range page requests, and gracefully handling errors. 

Provide informative error messages and proper HTTP status codes to guide API consumers in handling pagination-related issues.

Read: 7 ways to handle common errors and invalid requests in API pagination

7. Consider caching strategies

Implement caching mechanisms to store paginated data or metadata that does not frequently change. 

Caching can help improve performance by reducing the load on the server and reducing the response time for subsequent requests.

Here are some caching strategies you can consider: 

1. Page level caching

Cache the entire paginated response for each page. This means caching the data along with the pagination metadata. This strategy is suitable when the data is relatively static and doesn't change frequently.

2. Result set caching

Cache the result set of a specific query or combination of query parameters. This is useful when the same query parameters are frequently used, and the result set remains relatively stable for a certain period. You can cache the result set and serve it directly for subsequent requests with the same parameters.

3. Time-based caching

Set an expiration time for the cache based on the expected freshness of the data. For example, cache the paginated response for a certain duration, such as 5 minutes or 1 hour. Subsequent requests within the cache duration can be served directly from the cache without hitting the server.

4. Conditional caching

Use conditional caching mechanisms like HTTP ETag or Last-Modified headers. The server can respond with a 304 Not Modified status if the client's cached version is still valid. This reduces bandwidth consumption and improves response time when the data has not changed.

5. Reverse proxy caching

Implement a reverse proxy server like Nginx or Varnish in front of your API server to handle caching. 

Reverse proxies can cache the API responses and serve them directly without forwarding the request to the backend API server. 

This offloads the caching responsibility from the application server and improves performance.

Simplify API pagination 

In conclusion, implementing effective API pagination is essential for providing efficient and user-friendly access to large datasets. But it isn’t easy, especially when you are dealing with a large number of API integrations.

Using a unified API solution like Knit ensures that your API pagination requirements is handled without you requiring to do anything anything other than embedding Knit’s UI component on your end. 

Once you have integrated with Knit for a specific software category such as HRIS, ATS or CRM, it automatically connects you with all the APIs within that category and ensures that you are ready to sync data with your desired app. 

In this process, Knit also fully takes care of API authorization, authentication, pagination, rate limiting and day-to-day maintenance of the integrations so that you can focus on what’s truly important to you i.e. building your core product.

By incorporating these best practices into the design and implementation of paginated APIs, Knit creates highly performant, scalable, and user-friendly interfaces for accessing large datasets. This further helps you to empower your end users to efficiently navigate and retrieve the data they need, ultimately enhancing the overall API experience.

Whether you’re a SaaS founder, product manager, or part of the customer success team, one thing is non-negotiable — customer data privacy. If your users don’t trust how you handle data, especially when integrating with third-party tools, it can derail deals and erode trust.

Unified APIs have changed the game by letting you launch integrations faster. But under the hood, not all unified APIs work the same way — and Kombo.dev and Knit.dev take very different approaches, especially when it comes to data sync, compliance, and scalability.

Let’s break it down.

What is a Unified API?

Unified APIs let you integrate once and connect with many applications (like HR tools, CRMs, or payroll systems). They normalize different APIs into one schema so you don’t have to build from scratch for every tool.

A typical unified API has 4 core components:

• Authentication & Authorization
• Connectors
• Data Sync (initial + delta)
• Integration Management

Data Sync Architecture: Kombo vs Knit

Between the Source App and Unified API

• Kombo.dev uses a copy-and-store model. Once a user connects an app, Kombo:
  ‍
  • Pulls the data from the source app.
  • Stores a copy of that data on their servers.
  • Uses polling or webhooks to keep the copy updated.

‍

• Knit.dev is different: it doesn’t store any customer data.
  ‍
  • Once a user connects an app, Knit:
    • Delivers both initial and delta syncs via event-driven webhooks.
    • Pushes data directly to your app without persisting it anywhere.

Between the Unified API and Your App

• Kombo uses a pull model — you’re expected to call their API to fetch updates.
  ‍
• Knit uses a pure push model — data is sent to your registered webhook in real-time.

Why This Matters

‍

Authentication & Authorization

• Kombo offers pre-built UI components.
• Knit provides a flexible JS SDK + Magic Link flow for seamless auth customization.

This makes Knit ideal if you care about branding and custom UX.

‍As the nature of employment is constantly changing with dynamic employee benefit expectations, organizational payroll is seeing constant transformation. At the same time, payroll data is no longer used only for paying employees, but is increasingly being employed for a variety of other purposes. 

This diversification and added complexities of payroll has given rise to payroll APIs which are integral in bringing together the employment ecosystem for businesses to facilitate smooth transactions.

If you're just looking to quick start with a specific Payroll APP integration, you can find APP specific guides and resources in our Payrolll API Guides Directory

What are Payroll APIs?

Like all other APIs or application programming interfaces, payroll APIs help companies integrate their different applications or platforms that they use to manage employee payment details together for a robust payroll system. 

Essentially, it enables organizations to bring together details related to salary, benefits, payment schedule etc. and run this data seamlessly to ensure that all employees are compensated correctly and on time, facilitating greater satisfaction and motivation, while preventing any financial challenges for the company. 

Payroll concepts and information

To build or use any payroll API or HRIS integration, it is important that you understand the key payroll concepts and the information you will need to collect for effective execution. Since payroll APIs are domain specific, lack of knowledge of these concepts will make the process of integration complicated and slow. Thus, here is a quick list of concepts to get started.

1. Frequency and repetition 

The first concept you should start with focuses on understanding the frequency and repetition of payments. There are multiple layers to understand here. 

First, understand the frequency. In technical terms, it is called pay period. This refers to the number of times a payment is made within a specific period. For instance, it could be monthly, twice in a month, four times a month, etc. Essentially, it is how many times a payment is made within a particular period.

Second, is the repetition, also known as payroll runs. Within an organization, some employees are paid on a regular basis, while others might receive a one-time payment for specific projects. A payroll run defines whether or not the payment is recurring. Your payroll run will also constitute a status to help understand whether or not the payment has been made. In case the payment is being calculated, the status will likely be unprocessed. However, once it is complete, the status will change to paid or whatever nomenclature you use. 

2. Pay scale and in-hand pay

As a part of the payroll concepts, it is extremely important for you to understand terms like pay scale, in-hand pay, compensation, pay rate, deduction, reimbursements, etc. We’ll take them one at a time.

Pay scale/ Pay rate

A pay scale or pay rate determines the amount of salary that is due to an employee based on their level of experience, job role, title, tenure with the organization, etc. 

A pay scale or a pay rate can be in the form of an hourly or weekly or even a monthly figure, say INR xx per week or INR yy per hour. It may differ for people with similar experience at the same level, based on their tenure with the company, skills and competencies, etc. 

Compensation

Based on the pay scale or pay rate, a company can calculate the compensation due to any employee. Generally, the math for compensation isn’t linear. Compensation is also referred to as the gross pay which includes the pay rate multiplied by the time period that the employee has worked for along with other benefits like bonuses and commissions that might be due to the employee, based on their terms of employment. 

For instance, some organizations provide a one-time joining bonus, while others have sales incentives for their employees. All of these form a part of the compensation or gross pay. 

Benefits

In addition to the benefits mentioned above, an employee might be eligible for others including a health cover, leave-travel allowance, mental wellness allowance etc. These all together add up to benefits that an employee receives over and above the pay rate. 

Deductions

Within the compensation or the gross pay are parts of deductions, which are not directly paid to the employees. These deductions differ across countries and regions and even based on the size of the company. 

For instance, in India, companies have to deduct PF from the employee’s gross pay which is given to them at the time of retirement. However, if an organization is smaller than 20 people, this compliance doesn’t come into existence. At the same time, based on the pay scale and pay rate, there are tax deductions which are due. 

In-hand pay

The in-hand pay is essentially the amount an employee receives after addition of all due payment and subtraction of the aforementioned deductions. This is the payment that the employee receives in his/ her bank account.

Reimbursements

Another concept within the payroll is reimbursements. There might be some expenses that an employee undertakes based on the requirements of the job, which are not a part of the gross pay. For instance, an employee takes out a client for dinner or is traveling for company work. In such cases, the expenses borne by the employee are compensated to the employee. Reimbursements are generally direct and don’t incur any tax deductions.

3. Cost to employer

The above concepts together add up to the cost to the employer. This refers to how much an employee essentially costs to a company, including all the direct and indirect payments made to them. The calculation starts with the pay scale or pay rate to which other aspects like contribution to benefits and em

Payroll data models/ data schemas 

Now that you have an understanding of the major payroll concepts, you also need to be aware about the key data or information that you will need to comprehend to work on payroll APIs. 

Essentially, there are two types of data models that are most used in payroll APIs. One focuses on the employees and the other on the overall organization or company.

Employee details

From an employee standpoint, any payroll API will need to have the following details:

Location 

The part of the world where the employee resides. You need to capture not only the present but also the permanent address of the employee.

Profile 

Employee profile refers to a basic biography of the concerned person which includes their educational backgrounds, qualifications, experience, areas of expertise, etc. These will help you understand which pay scale they will fit into and define the compensation in a better way. It is equally important to get their personal details like date of birth, medical history, etc. 

ID

An employee ID will help you give a unique identifier to each employee and ensure all payments are made correctly. There might be instances where two or more employees share the same name or other details. An employee ID will help differentiate the two and process their payrolls correctly. 

Dependents 

Information on dependents like elderly parents, spouses and children will help you get a better picture of the employee’s family. This is important from a social security and medicare perspective that is often extended to dependents of employees.

Company details

When it comes to company details, working with a payroll API, you need to have a fair understanding of the organizational structure. The idea is to understand the hierarchy within the organization, the different teams as well as to get manager details for each employee.

A simple use case includes reimbursements. Generally, reimbursements require an approval from the direct reporting manager. Having this information can make your payroll API work effectively.

Top payroll API use cases

Invariably, a payroll API can help you integrate different information related to an employee’s payroll and ensure a smooth payment process. However, it is interesting to note that many SaaS companies are now utilizing this payroll data collected from payroll APIs with HRIS integration to power their operations. Some of the top payroll API use cases include:

1. Insurance and lending

Often, information about payroll and income for individuals is siloed and insurance and lending companies have to navigate through dozens of documents to determine whether or not the individual is eligible for any kind of insurance or loans. Fortunately, with payroll APIs, this becomes easy by enabling several benefits. 

• First, payroll API can help lenders or insurance agents with streamlined information on whether or not the person has the ability to pay the installments or loans. 
• Second, any kind of lending also requires a background verification which payroll APIs with HRIS integration can easily provide. Thus, with payroll APIs, SaaS based insurance and lending companies can easily process verification and loan underwriting. 

2. Accounting

Accounting and tax management companies have for long struggled with manual paperwork to file company taxes which comply with the national and regional norms. With payroll API, SaaS based accounting firms find it extremely easy to access all employee related tax information at one place. They can see the benefits offered to different employees, overall compensation, reimbursements and all other payroll related technicalities which were earlier siloed. 

Armed with this data, courtesy payroll APIs, accounting firms find their work has been highly streamlined as they no longer have to manually document all information and then work to verify its accuracy and compliance.

3. Employee benefit companies

There are several SaaS companies today that are helping businesses set up their benefits plans and services for high levels of employee satisfaction. These employee benefits companies can take help of data from payroll APIs to help businesses customize their benefits packages to best suit employee expectations and trends. 

For instance, you might want to have different benefits for full-time versus contractual employees. With payroll API data, employee benefit companies can help businesses make financially prudent decisions for employee benefits. 

4. Performance management systems

The recent years have seen a rise in the adoption of performance management systems which can help businesses adopt practices for better employee performance. Armed with HRIS and payroll API data from different companies, these companies can identify motivators in payroll for better performance and even help identify rate of absenteeism and causes of poor performance. 

Such SaaS based companies use payroll APIs to understand which pay scale employees take more time off, what their benefits look like and how this gap can be bridge to facilitate better performance. Invariably, here, payroll data can help streamline performance management from a benefits, incentives and compensation standpoint.As well as, it makes HRIS data makes it a one click process to gather all relevant employee information. 

5. Consumer fintech companies

Consumer fintech companies, like those in direct deposit switching, are increasingly leveraging payroll APIs to facilitate their operations. Payroll API integrations allow consumers to directly route their deposits through their payroll with direct deposit switching. The account receiving the deposit is directly linked to the employee’s payroll account, making it easy for consumer fintech companies to increase their transactions, without manual intervention which increases friction and reduces overall value. 

5. Commercial insurance 

Finally, there are SaaS companies that deal with commercial insurance for companies for different purposes. Be it health or any other, payroll API data can help them get a realistic picture of the company’s people posture and their payroll information which can help these commercial insurance companies suggest the best plans for them as well as ensure that the employees are able to make the payments. They can achieve all of this without having to manually process data for all employees across the organization.

Payroll fragmentation challenges

Research shows that the payroll market is poised to grow at a CAGR of 9.2% between 2022 and 2031, reaching $55.69 billion by 2031. 

While the growth is promising, the payroll market is extremely fragmented. Undoubtedly, there are a few players like ADP RUN, Workday, etc. which have a significant market share. However, the top 10 players in the space constitute only about 55%-60% share, which clearly illustrates the presence of multiple other smaller companies. In fact, as you go down from the top 2-3 to the top 10, the market share for individual applications dwindles down to 1% each. 

Here is a quick snapshot of the payroll market segmentation to help understand its fragmented nature and the need for a unified solution to make sense of payroll APIs. 

Before moving on to how payroll fragmentation can be addressed with a unified solution, it is important to understand why this fragmentation exists. The top reasons include:

Changing and diverse employee demographics

First, different businesses have different demographics and industries that they cater to. Irrespective of the features, each business is looking for a payroll solution that provides them with the best pricing based on their number of employees and employment terms. While some might have a large number of full time salaried employees, others might have a large number of contractual workers, while the third kind might have a balanced mix of both. These diverse demographic requirements have given birth to different payroll applications, fragmenting the market. 

Dynamic market conditions

Next, it is important to understand that market conditions and employment terms are constantly in flux. 

• On one hand, the compensation and benefits expectations are continually changing. 
• On the other hand, with the rise of remote and hybrid work, employment models are undergoing transformation. 

Therefore, as businesses need new and fresh approaches to deal with their payroll requirements, a consequent rise of fragmentation can be observed. 

New and tech enabled solutions

Finally, organizations are increasingly adopting white labeled or embedded payroll solutions which enable them to either brand the solutions with their name or embed the API into their existing product. This is enabling market players in other verticals to also enter the payroll market, which further adds to the fragmentation. 

• On one hand, there are completely new SaaS players entering the market to address new business needs and changing market conditions. 
• On the other hand, existing players from other verticals are adding to their capabilities to address payroll requirements. 

Unified API for payroll integration

With so many payroll applications in the market for HRMS integration, it can be extremely daunting for businesses to make sense of all payroll related data. At the same time, it is difficult to manage data exchange between different payroll applications you might be using. Therefore, a unified payroll API can help make the process easy. 

Data normalization

First, the data needs to be normalized. This means that your unified payroll API will normalize and funnel data from all payroll providers about each employee into a consistent, predictable and easy to understand data format or syntax, which can be used. 

Data management

Second, a unified API will help you manage all employee payroll data in the form of unified logs with an API key to ensure that you can easily retrieve the data as and when needed. 

Make informed decisions

Finally, a unified payroll API can help ensure that you are able to make sense of the payroll data and make informed decisions during financial planning and analysis on factors like pay equity, financial prudence, etc. 

Payroll API data with Knit 

As a unified payroll API, Knit can help you easily get access to the following payroll data from different payroll applications that you might be using to facilitate seamless payment processing and payroll planning for the next financial year. 

Employee Profile

Seamlessly retrieve all employee data like first name, last name, unique ID, date of birth, work email, start date, termination data in case of former employees, marital data and employment type. 

Employee Organizational Structure

Hierarchical data for the employee, including information on the employee’s title and designation, department, manager details, subordinates or those who report to the employee, etc. 

Employee Dependents

Details about the family members of the employees including children, spouse and parents. The information includes name, relation, date of birth and other specific data points which can be useful when you are negotiating insurance and other benefits with third party companies. 

Employee Location 

Information on where the employee currently resides, specific address as well as the permanent address for the employee. 

Employee payroll

All kinds of details about the compensation for the employee, including gross pay, net pay, benefits and other earnings like commissions, bonuses, employee contributions to benefits, employer contributions, taxes and other deductions, reimbursements, etc. 

Wrapping up: TL:DR

Overall, if you observe it is very clear that increasingly, the payroll market is becoming more and more fragmented. Invariably, it is becoming extremely difficult for businesses using multiple payroll applications to normalize all data to facilitate understanding and exchange. To make sense of payroll APIs, you need to first acquaint yourself with the key payroll concepts like pay period, payroll run, compensation, in-hand pay, gross pay, reimbursements, benefits and deductions, etc. 

Once you understand these, you will agree that a payroll API can make the payment process seamless by helping in employee onboarding and payroll integration, management of reimbursements, administration of benefits and easy deductions, tax and net pay management, accounting and financial planning, among others. 

Increasingly, data from payroll APIs is also enabling other SaaS companies to power their operations, especially in the finance and fintech space. If you look closely, lending, insurance, portfolio management, etc. have become very streamlined, automated with a reduced reliance on manual process. At the same time, HR management has also become simplified, especially across performance management. Payroll data can help performance management companies help businesses identify the right incentive structure to motivate high performance. 

However, with increasing fragmentation, a unified payroll API can help businesses easily extract salary information, data on benefits and deductions and records about how and when the employees have been paid along with tax related information from a single source. Thus, if  you are adopting payroll API, look out for data normalization and data management for maximum business effectiveness.

1. Introduction: Why CRM API Integration Matters

Customer Relationship Management (CRM) platforms have evolved into the primary repository of customer data, tracking not only prospects and leads but also purchase histories, support tickets, marketing campaign engagement, and more. In an era when organizations rely on multiple tools—ranging from enterprise resource planning (ERP) systems to e-commerce solutions—the notion of a solitary, siloed CRM is increasingly impractical.

If you're just looking to quick start with a specific CRM APP integration, you can find APP specific guides and resources in our CRM API Guides Directory

CRM API integration answers the call for a more unified, real-time data exchange. By leveraging open (or proprietary) APIs, businesses can ensure consistent records across marketing campaigns, billing processes, customer support tickets, and beyond. For instance:

• Salesforce API integration might automatically push closed-won deals to your billing platform.
• HubSpot API integration can retrieve fresh lead info from a sign-up form and sync it with your sales pipeline.
• Pipedrive API integration enables your e-commerce CRM integration to update inventory or order statuses in the CRM.
• Zendesk crm integrations ensure every support ticket surfaces in the CRM for 360° visibility.

Whether you need a Customer Service CRM Integration, ERP CRM Integration, or you’re simply orchestrating a multi-app ecosystem, the idea remains the same: consistent, reliable data flow across all systems. This in-depth guide shows why CRM API integration is critical, how it works, and how you can tackle the common hurdles to excel in crm data integration.

2. Defining CRM API Integration

An API, or application programming interface, is essentially a set of rules and protocols allowing software applications to communicate. CRM API integration harnesses these endpoints to read, write, and update CRM records programmatically. It’s the backbone for syncing data with other business applications.

Key Features of CRM API Integration

1. Bidirectional Sync
   Data typically flows both ways: for instance, a change in the CRM (e.g., contact status) triggers an update in your billing system, while new transactions in your e-commerce store could update a contact’s record in the CRM.
2. Real-Time or Near-Real-Time Updates
   Many CRM APIs support webhooks or event-based triggers for near-instant data pushes. Alternatively, scheduled batch sync may suffice for simpler use cases.
3. Scalability
   With the right architecture, a CRM integration can scale from handling dozens of records per day to thousands, or even millions, across a global user base.
4. Security and Authentication
   OAuth, token-based, or key-based authentication ensures only authorized systems can access or modify CRM data.

In short, a well-structured crm integration strategy ensures that no matter which department or system touches customer data, changes feed back into a master record—your CRM.

3. Key Business Cases for CRM API Integration

A. Sales Automation

• Salesforce API integration: A classic scenario is linking Salesforce to your marketing automation or ERP. When a lead matures into an opportunity and closes, the details populate the ERP for order fulfillment or invoicing.
• HubSpot API integration: Automatically push lead scoring info from marketing channels so sales reps receive timely, enriched data.

B. E-Commerce CRM Integration

• Real-time updates to product inventory, sales volumes, and client purchase history.
• Streamline cross-sell and upsell campaigns by sharing e-commerce data with the CRM.
• Automate personalized follow-ups for cart abandonments or reorder reminders.

C. ERP CRM Integration

• ERP systems commonly manage finances, logistics, and back-office tasks. Syncing them with the CRM provides a single truth for contract values, billing statuses, or supply chain notes.
• Minimizes friction between sales teams and finance by automating invoicing triggers.

D. Customer Service CRM Integration

• Zendesk crm integrations: Combine helpdesk tickets with contact or account records in the CRM for more personal, consistent service.
• Support teams can escalate critical issues into high-priority tasks for account managers, bridging departmental silos.

E. Data Analytics & Reporting

• Extract aggregated CRM data for BI dashboards, advanced segmentation, or forecasting.
• Align data across different platforms—so marketing, sales, and product usage data all merge into a single analytics repository.

F. Partner Portals and External Systems

• Some organizations need to feed data to reseller portals or affiliates. A crm api fosters a direct pipeline, controlling access and ensuring data accuracy.
• Use built-in logic (e.g., custom fields in your CRM) to define different data for different partner levels.

4. Top Benefits of Connecting CRM Via APIs

1. Unified Data, Eliminated Silos
Gone are the days when a sales team’s pipeline existed in one system while marketing data or product usage metrics lived in another. CRM API integration merges them all, guaranteeing alignment across the organization.

2. Greater Efficiency and Automation
Manual data entry is not only tedious but prone to errors. An automated, API-based approach dramatically reduces time-consuming tasks and data discrepancies.

3. Enhanced Visibility for All Teams
When marketing can see new leads or conversions in real time, they adjust campaigns swiftly. When finance can see payment statuses in near-real-time, they can forecast revenue more accurately. Everyone reaps the advantages of crm integration.

4. Scalability and Flexibility
As your business evolves—expanding to new CRMs, or layering on new apps for marketing or customer support—unified crm api solutions or robust custom integrations can scale quickly, saving months of dev time.

5. Improved Customer Experience
Customers interacting with your brand expect you to “know who they are” no matter the touchpoint. With consolidated data, each department sees an updated, comprehensive profile. That leads to personalized interactions, timely support, and better overall satisfaction.

5. Core Data Concepts in CRM Integrations

Before diving into an integration project, you need a handle on how CRM data typically gets structured:

Contacts and Leads

• Contacts: Usually individuals or key stakeholders you interact with.
• Leads: Sometimes a separate object in CRMs like Salesforce or HubSpot, leads are unqualified prospects. Once qualified, they may convert into a contact or account.

Accounts or Organizations

• Many CRMs link contacts to overarching accounts or organizations. This helps group multiple contacts from the same company.

Opportunities or Deals

• Represents potential revenue in the pipeline. Typically assigned a stage, expected close date, or forecasted amount.

Tasks, Activities, and Notes

• Summaries of calls, meetings, or custom tasks. Often crucial for a customer service crm integration scenario, as support notes or ticket interactions might appear here.

Custom Fields and Objects

• Nearly all major CRMs (e.g., Salesforce, HubSpot, Pipedrive) allow businesses to add unique data fields or entire custom objects.
• crm data integration must account for these non-standard fields, or risk incomplete sync.

Pipeline Stages or Lifecycle Stages

• Usually a set of statuses for leads, deals, or support cases. For example, “Prospecting,” “Qualified,” “Proposal,” “Closed Won/Lost.”

Understanding how these objects fit together is fundamental to ensuring your crm api integration architecture doesn’t lose track of crucial relationships—like which contact belongs to which account or which deals are associated with a particular contact.

6. Approaches to CRM API Integration

When hooking up your CRM with other applications, you have multiple strategies:

1. Direct, Custom Integrations

• Pros: Fine control over every API call, deeper customization, no reliance on third parties.
• Cons: Time-consuming to build and maintain—especially if you need to handle each system’s rate limits, version updates, or security quirks.

If your company primarily uses a single CRM (like Salesforce) and just needs one or two integrations (e.g., with an ERP or marketing tool), a direct approach can be cost-effective.

2. Integration Platforms (iPaaS)

• Examples include Workato, MuleSoft, Tray.io, Boomi.
• Pros: Pre-built connectors, drag-and-drop workflows, relatively quick to deploy.
• Cons: Typically require a 1:1 approach for each system, may involve licensing fees that scale with usage.

While iPaaS solutions can handle e-commerce crm integration, ERP CRM Integration, or other patterns, advanced custom logic or heavy data loads might still demand specialized dev work.

3. Unified CRM API Solutions

• Pros: Connect multiple CRMs (Salesforce, HubSpot, Pipedrive, Zendesk CRM, etc.) via a single interface. Perfect if you serve external customers who each use different CRMs.
• Cons: Must confirm the solution supports advanced or custom fields.

A unified crm api is often a game-changer for SaaS providers offering crm integration services to their users, significantly slashing dev overhead.

4. CRM Integration Services or Consultancies

• Pros: Offload the complexity to specialists who’ve done it before.
• Cons: Potentially expensive, plus external vendors might not be as agile or on-demand as in-house dev teams.

When you need complicated logic (like an enterprise-level erp crm integration with specialized flows for ordering, shipping, or financial forecasting) or advanced custom objects, a specialized agency can accelerate time-to-value.

7. Challenges and Best Practices

Though CRM API integration is transformative, it comes with pitfalls.

Key Challenges

1. Rate Limits and Throttling
   
   • Many CRMs (e.g., HubSpot, Salesforce, Pipedrive) limit how many API calls you can make in a given time.
   • Overuse leads to temporary blocks, halting data sync.
2. API Versioning
   
   • CRMs evolve. An endpoint you rely on might be deprecated or changed. Keeping track can be a dev headache.
3. Security & Access Control
   
   • CRM data often includes personally identifiable information (PII). Proper encryption, token-based access, or OAuth protocols are mandatory.
4. Data Mapping & Transformation
   
   • Mismatched fields across systems cause confusion. For instance, an “industry” field might exist in the CRM but not in your other tool, or be spelled differently.
   • Mistakes lead to partial or failed sync attempts, requiring manual cleanup.
5. Lack of Real-Time Sync
   
   • Some CRMs only support scheduled or batch processes. This might hamper urgent updates or time-sensitive workflows.

Best Practices for a Smooth CRM Integration

1. Design for Extensibility
   
   • Even if you only integrate two apps today, plan for tomorrow’s expansions. Adopting a “hub and spoke” or unified approach is wise if you expect more integrations.
2. Test in a Sandbox
   
   • Popular CRMs like Salesforce or HubSpot provide sandbox or developer environments. Thorough testing prevents surprising data issues in production.
3. Implement Retry and Exponential Backoff
   
   • If a request hits a rate limit, do you keep spamming the endpoint or wait? Properly coded backoff logic is crucial.
4. Establish Logging & Alerting
   
   • Track each sync event, capturing success/fail outcomes. Flag partial sync errors for immediate dev investigation.
5. Document the Integration
   
   • Outline the data flow, field mappings, and any custom transformation logic. This is invaluable for new dev hires or vendor transitions.
6. Secure with Principle of Least Privilege
   
   • The integration shouldn’t get read/write access to every CRM record if it only needs half. Minimizing privileges helps mitigate risk if credentials leak.

8. Implementation Steps: Getting Technical

For teams that prefer a direct or partially custom approach to crm api integration, here’s a rough, step-by-step guide.

Step 1: Requirements and Scope

• Pinpoint which objects you need (e.g., contacts, opportunities).
• Decide if data is read-only or read/write.
• Do you need real-time (webhooks) or batch-based sync?

Step 2: Auth and Credential Setup

• CRMs commonly use OAuth 2.0 (e.g., salesforce api integration), Basic Auth, or token-based authentication.
• Store tokens securely (e.g., in a secrets manager) and rotate them if needed.

Step 3: Data Modeling & Mapping

• Outline how each CRM field (Lead.Email) corresponds to fields in your application (User.Email).
• Identify required transformations (e.g., date formats, currency conversions).

Step 4: Handle Rate Limits and Throttling

• Implement an intelligent queue or job system.
• If you encounter a 429 (too many requests) or an error from the CRM, pause that job or retry with backoff.

Step 5: Set Up Logging and Monitoring

• Monitor success/failure counts, average response times, error codes.
• Real-time logs or a time-series database can help you proactively detect unusual spikes.

Step 6: Testing and Validation

• Use staging or sandbox accounts where possible.
• Validate your integration with real sample data (e.g., a small subset of contacts).
• Confirm that updates in the CRM reflect accurately in your external app and vice versa.

Step 7: Rollout and Post-Launch Maintenance

• Deploy in stages—maybe first to a pilot department or subset of users.
• Gather feedback, watch logs. Then ramp up more data once stable.
• Schedule routine checks for new CRM versions or endpoint changes.

9. Trends & Future Outlook

CRM API integration is rapidly evolving alongside shifts in the broader SaaS ecosystem:

1. Low-Code/No-Code Movement
   
   • Tools like Zapier or Airtable-like platforms now integrate with CRMs, letting non-dev teams build basic automations.
   • However, advanced or enterprise-level logic often still demands custom coding or robust iPaaS solutions.
2. AI & Machine Learning
   
   • As CRMs incorporate AI for lead scoring or forecasting, integration strategies may need to handle real-time insight updates.
   • AI-based triggers—for example, an AI model identifies a churn-risk lead—could push data into other workflow apps instantly.
3. Real-Time Event-Driven Architectures
   
   • Instead of batch-based nightly sync, more CRMs are adding robust webhook frameworks.
   • E.g., an immediate notification if an opportunity’s stage changes, which an external system can act on.
4. Unified CRM API Gains Traction
   
   • SaaS providers realize building connectors for each CRM is unsustainable. Using a single aggregator interface can accelerate product dev, especially if customers use multiple CRMs.
5. Industry-Specific CRM Platforms
   
   • Healthcare, finance, or real estate CRMs each have unique compliance or data structure needs. Integration solutions that handle domain-specific complexities are poised to win.

Overall, expect crm integration to keep playing a pivotal role as businesses expand to more specialized apps, push real-time personalization, and adopt AI-driven workflows.

10. FAQ on CRM API Integration

In today's AI-driven world, AI agents have become transformative tools, capable of executing tasks with unparalleled speed, precision, and adaptability. From automating mundane processes to providing hyper-personalized customer experiences, these agents are reshaping the way businesses function and how users engage with technology. However, their true potential lies beyond standalone functionalities—they thrive when integrated seamlessly with diverse systems, data sources, and applications.

This integration is not merely about connectivity; it’s about enabling AI agents to access, process, and act on real-time information across complex environments. Whether pulling data from enterprise CRMs, analyzing unstructured documents, or triggering workflows in third-party platforms, integration equips AI agents to become more context-aware, action-oriented, and capable of delivering measurable value.

This article explores how seamless integrations unlock the full potential of AI agents, the best practices to ensure success, and the challenges that organizations must overcome to achieve seamless and impactful integration.

Rise of AI Agents

The rise of Artificial Intelligence (AI) agents marks a transformative shift in how we interact with technology. AI agents are intelligent software entities capable of performing tasks autonomously, mimicking human behavior, and adapting to new scenarios without explicit human intervention. From chatbots resolving customer queries to sophisticated virtual assistants managing complex workflows, these agents are becoming integral across industries.

This rise of use of AI agents has been attributed to factors like:

• Advances in AI and machine learning models, and access to vast datasets which allow AI agents to understand natural language better and execute tasks more intelligently.
• Demand for automating routine tasks, reducing the burden on human resources, and improving efficiency, driving operational efficiency

Understanding How AI Agents Work

AI agents are more than just software programs; they are intelligent systems capable of executing tasks autonomously by mimicking human-like reasoning, learning, and adaptability. Their functionality is built on two foundational pillars: 

1) Contextual Knowledge

For optimal performance, AI agents require deep contextual understanding. This extends beyond familiarity with a product or service to include insights into customer pain points, historical interactions, and updates in knowledge. However, to equip AI agents with this contextual knowledge, it is important to provide them access to a centralized knowledge base or data lake, often scattered across multiple systems, applications, and formats. This ensures they are working with the most relevant and up-to-date information. Furthermore, they need access to all new information, such as product updates, evolving customer requirements, or changes in business processes, ensuring that their outputs remain relevant and accurate.

For instance, an AI agent assisting a sales team must have access to CRM data, historical conversations, pricing details, and product catalogs to provide actionable insights during a customer interaction.

2) Strategic Action

AI agents’ value lies not only in their ability to comprehend but also to act. For instance, AI agents can perform activities such as updating CRM records after a sales call, generating invoices, or creating tasks in project management tools based on user input or triggers. Similarly, AI agents can initiate complex workflows, such as escalating support tickets, scheduling appointments, or launching marketing campaigns. However, this requires seamless connectivity across different applications to facilitate action. 

For example, an AI agent managing customer support could resolve queries by pulling answers from a knowledge base and, if necessary, escalating unresolved issues to a human representative with full context.

The capabilities of AI agents are undeniably remarkable. However, their true potential can only be realized when they seamlessly access contextual knowledge and take informed actions across a wide array of applications. This is where integrations play a pivotal role, serving as the key to bridging gaps and unlocking the full power of AI agents.

Enter Integrations: Powering AI Agents

The effectiveness of an AI agent is directly tied to its ability to access and utilize data stored across diverse platforms. This is where integrations shine, acting as conduits that connect the AI agent to the wealth of information scattered across different systems. These data sources fall into several broad categories, each contributing uniquely to the agent's capabilities:

Types of Agent Data Sources: The Foundation of AI Agent Functionality

1) Structured Data Sources

Platforms like databases, Customer Relationship Management (CRM) systems (e.g., Salesforce, HubSpot), and Enterprise Resource Planning (ERP) tools house structured data—clean, organized, and easily queryable. For example, CRM integrations allow AI agents to retrieve customer contact details, sales pipelines, and interaction histories, which they can use to personalize customer interactions or automate follow-ups.

2) Unstructured Data Sources

The majority of organizational knowledge exists in unstructured formats, such as PDFs, Word documents, emails, and collaborative platforms like Notion or Confluence. Cloud storage systems like Google Drive and Dropbox add another layer of complexity, storing files without predefined schemas. Integrating with these systems allows AI agents to extract key insights from meeting notes, onboarding manuals, or research reports. For instance, an AI assistant integrated with Google Drive could retrieve and summarize a company’s annual performance review stored in a PDF document.

3) Streaming Data Sources

Real-time data streams from IoT devices, analytics tools, or social media platforms offer actionable insights that are constantly updated. AI agents integrated with streaming data sources can monitor metrics, such as energy usage from IoT sensors or engagement rates from Twitter analytics, and make recommendations or trigger actions based on live updates.

4) Third-Party Applications

APIs from third-party services like payment gateways (Stripe, PayPal), logistics platforms (DHL, FedEx), and HR systems (BambooHR, Workday) expand the agent's ability to act across verticals. For example, an AI agent integrated with a payment gateway could automatically reconcile invoices, track payments, and even issue alerts for overdue accounts.

The Role of Data Ingestion 

To process this vast array of data, AI agents rely on data ingestion—the process of collecting, aggregating, and transforming raw data into a usable format. Data ingestion pipelines ensure that the agent has access to a broad and rich understanding of the information landscape, enhancing its ability to make accurate decisions.

However, this capability requires robust integrations with a wide variety of third-party applications. Whether it's CRM systems, analytics tools, or knowledge repositories, each integration provides an additional layer of context that the agent can leverage.

Without these integrations, AI agents would be confined to static or siloed information, limiting their ability to adapt to dynamic environments. For example, an AI-powered customer service bot lacking integration with an order management system might struggle to provide real-time updates on a customer’s order status, resulting in a frustrating user experience.

The Case for Real-Time Integrations

In many applications, the true value of AI agents lies in their ability to respond with real-time or near-real-time accuracy. Integrations with webhooks and streaming APIs enable the agent to access live data updates, ensuring that its responses remain relevant and timely.

Consider a scenario where an AI-powered invoicing assistant is tasked with generating invoices based on software usage. If the agent relies on a delayed data sync, it might fail to account for a client’s excess usage in the final moments before the invoice is generated. This oversight could result in inaccurate billing, financial discrepancies, and strained customer relationships.

Why Agents Need Integrations:

1) Empowering Action Across Applications

Integrations are not merely a way to access data for AI agents; they are critical to enabling these agents to take meaningful actions on behalf of other applications. This capability is what transforms AI agents from passive data collectors into active participants in business processes. 

Integrations play a crucial role in this process by connecting AI agents with different applications, enabling them to interact seamlessly and perform tasks on behalf of the user to trigger responses, updates, or actions in real time. 

For instance, A customer service AI agent integrated with CRM platforms can automatically update customer records, initiate follow-up emails, and even generate reports based on the latest customer interactions. SImilarly, if a popular product is running low, the AI agent for e-commerce platform can automatically reorder from the supplier, update the website’s product page with new availability dates, and notify customers about upcoming restocks. Furthermore, A marketing AI agent integrated with CRM and marketing automation platforms (e.g., Mailchimp, ActiveCampaign) can automate email campaigns based on customer behaviors—such as opening specific emails, clicking on links, or making purchases. 

Integrations allow AI agents to automate processes that span across different systems. For example, an AI agent integrated with a project management tool and a communication platform can automate task assignments based on project milestones, notify team members of updates, and adjust timelines based on real-time data from work management systems.

For developers driving these integrations, it’s essential to build robust APIs and use standardized protocols like OAuth for secure data access across each of the applications in use. They should also focus on real-time synchronization to ensure the AI agent acts on the most current data available. Proper error handling, logging, and monitoring mechanisms are critical to maintaining reliability and performance across integrations. Furthermore, as AI agents often interact with multiple platforms, developers should design integration solutions that can scale. This involves using scalable data storage solutions, optimizing data flow, and regularly testing integration performance under load.

2) Building RAG (Retrieval-Augmented Generation) pipelines

Retrieval-Augmented Generation (RAG) is a transformative approach that enhances the capabilities of AI agents by addressing a fundamental limitation of generative AI models: reliance on static, pre-trained knowledge. RAG fills this gap by providing a way for AI agents to efficiently access, interpret, and utilize information from a variety of data sources. Here’s how iintegrations help in building RAG pipelines for AI agents:

Access to Diverse Data Sources

Traditional APIs are optimized for structured data (like databases, CRMs, and spreadsheets). However, many of the most valuable insights for AI agents come from unstructured data—documents (PDFs), emails, chats, meeting notes, Notion, and more. Unstructured data often contains detailed, nuanced information that is not easily captured in structured formats.

RAG enables AI agents to access and leverage this wealth of unstructured data by integrating it into their decision-making processes. By integrating with these unstructured data sources, AI agents:

• Employ Optical Character Recognition (OCR) for scanned documents and Natural Language Processing (NLP) for text extraction.
• Use NLP techniques like keyword extraction, named entity recognition, sentiment analysis, and topic modeling to parse and structure the information.
• Convert text into vector embeddings using models such as Word2Vec, GloVe, and BERT, which represent words and phrases as numerical vectors capturing semantic relationships between them.
• Use similarity metrics (e.g., cosine similarity) to find relevant patterns and relationships between different pieces of data, allowing the AI agent to understand context even when information is fragmented or loosely connected.

Unified Retrieval Layer

RAG involves not only the retrieval of relevant data from these sources but also the generation of responses based on this data. It allows AI agents to pull in information from different platforms, consolidate it, and generate responses that are contextually relevant. 

For instance, an HR AI agent might need to pull data from employee records, performance reviews, and onboarding documents to answer a question about benefits. RAG enables this agent to access the necessary context and background information from multiple sources, ensuring the response is accurate and comprehensive  through a single retrieval mechanism.

Real-Time Contextual Understanding

RAG empowers AI agents by providing real-time access to updated information from across various platforms with the help of Webhooks. This is critical for applications like customer service, where responses must be based on the latest data. 

For example, if a customer asks about their recent order status, the AI agent can access real-time shipping data from a logistics platform, order history from an e-commerce system, and promotional notes from a marketing database—enabling it to provide a response with the latest information. Without RAG, the agent might only be able to provide a generic answer based on static data, leading to inaccuracies and customer frustration.

Key Benefits of RAG for AI Agents

1. Enhanced Accuracy
   By incorporating real-time information retrieval, RAG reduces the risk of hallucinations—a common issue with LLMs—ensuring responses are accurate and grounded in authoritative data sources.
2. Scalability Across Domains and Use Cases
   With access to external knowledge repositories, AI agents equipped with RAG can seamlessly adapt to various industries, such as healthcare, finance, education, and e-commerce.
3. Improved User Experience
   RAG-powered agents offer detailed, context-aware, and dynamic responses, elevating user satisfaction in applications like customer support, virtual assistants, and education platforms.
4. Cost Efficiency
   By offloading the need to encode every piece of knowledge into the model itself, RAG allows smaller LLMs to perform at near-human accuracy levels, reducing computational costs.
5. Future-Proofing AI Systems
   Continuous learning becomes effortless as new information can be integrated into the retriever without retraining the generator, making RAG an adaptable solution in fast-evolving industries.

Real-World Use Cases of integrations for AI Agents

AI-Powered Customer Support for an eCommerce Platform

Integration of an AI-powered customer service agent with CRM systems, ticketing platforms, and other tools can help enhance contextual knowledge and take proactive actions, delivering a superior customer experience. 

‍

For instance, when a customer reaches out with a query—such as a delayed order—the AI agent retrieves their profile from the CRM, including past interactions, order history, and loyalty status, to gain a comprehensive understanding of their background. Simultaneously, it queries the ticketing system to identify any related past or ongoing issues and checks the order management system for real-time updates on the order status. Combining this data, the AI develops a holistic view of the situation and crafts a personalized response. It may empathize with the customer’s frustration, offer an estimated delivery timeline, provide goodwill gestures like loyalty points or discounts, and prioritize the order for expedited delivery.

‍

The AI agent also performs critical backend tasks to maintain consistency across systems. It logs the interaction details in the CRM, updating the customer’s profile with notes on the resolution and any loyalty rewards granted. The ticketing system is updated with a resolution summary, relevant tags, and any necessary escalation details. Simultaneously, the order management system reflects the updated delivery status, and insights from the resolution are fed into the knowledge base to improve responses to similar queries in the future. Furthermore, the AI captures performance metrics, such as resolution times and sentiment analysis, which are pushed into analytics tools for tracking and reporting.

Retail AI Agent with Omni-Channel Integration

In retail, AI agents can integrate with inventory management systems, customer loyalty platforms, and marketing automation tools for enhancing customer experience and operational efficiency. For instance, when a customer purchases a product online, the AI agent quickly retrieves data from the inventory management system to check stock levels. It can then update the order status in real time, ensuring that the customer is informed about the availability and expected delivery date of the product. If the product is out of stock, the AI agent can suggest alternatives that are similar in features, quality, or price, or provide an estimated restocking date to prevent customer frustration and offer a solution that meets their needs. 

‍

Similarly, if a customer frequently purchases similar items, the AI might note this and suggest additional products or promotions related to these interests in future communications. By integrating with marketing automation tools, the AI agent can personalize marketing campaigns, sending targeted emails, SMS messages, or notifications with relevant offers, discounts, or recommendations based on the customer’s previous interactions and buying behaviors. The AI agent also writes back data to customer profiles within the CRM system. It logs details such as purchase history, preferences, and behavioral insights, allowing retailers to gain a deeper understanding of their customers’ shopping patterns and preferences. 

Key challenges with integrations for AI agents

Integrating AI (Artificial Intelligence) and RAG (Recommendations, Actions, and Goals) frameworks into existing systems is crucial for leveraging their full potential, but it introduces significant technical challenges that organizations must navigate. These challenges span across data ingestion, system compatibility, and scalability, often requiring specialized technical solutions and ongoing management to ensure successful implementation.

Data Compatibility and Quality:

• Data Fragmentation: Many organizations operate in data-rich but siloed environments, where critical information is scattered across multiple tools and platforms. For instance, customer data may reside in CRMs, operational data in ERP systems, and communication data in collaboration tools like Slack or Google Drive. These systems often store data in incompatible formats, making it difficult to consolidate into a single, accessible source. This fragmentation obstructs AI's ability to deliver actionable insights by limiting its access to the complete context required for accurate recommendations and decisions. Overcoming this challenge is particularly difficult in organizations with legacy systems or highly customized architectures.
• Data Quality Issues: AI systems rely heavily on data accuracy, completeness, and consistency. Common issues such as duplicate records, missing fields, or outdated entries can severely undermine the performance of AI models. Inconsistent data formatting, such as differences in date structures, naming conventions, or measurement units across systems, can lead to misinterpretation of information by AI agents. Low-quality data not only reduces the effectiveness of AI but also erodes stakeholder confidence in the system's outputs, creating a cycle of distrust and underutilization.

Complexity of Integration:

• System Compatibility: Integrating AI frameworks with existing platforms is often hindered by discrepancies in system architecture, API protocols, and data exchange standards. Enterprise systems such as CRMs, ERPs, and proprietary databases are frequently designed without interoperability in mind. These compatibility issues necessitate custom integration solutions, which can be time-consuming and resource-intensive. Additionally, the lack of standardization across APIs complicates the development process, increasing the risk of integration failures or inconsistent data flow.
• Real-Time Integration: Real-time functionality is critical for AI systems that generate recommendations or perform actions dynamically. However, achieving this is particularly challenging when dealing with high-frequency data streams, such as those from IoT devices, e-commerce platforms, or customer-facing applications. Low-latency requirements demand advanced data synchronization capabilities to ensure that updates are processed and reflected instantaneously across all systems. Infrastructure limitations, such as insufficient bandwidth or outdated hardware, further exacerbate this challenge, leading to performance degradation or delayed responses.

Scalability Issues:

• High Volume or Large Data Ingestion: AI integrations often require processing enormous volumes of data generated from diverse sources. These include transactional data from e-commerce platforms, behavioral data from user interactions, and operational data from business systems. Managing these data flows requires robust infrastructure capable of handling high throughput while maintaining data accuracy and integrity. The dynamic nature of data sources, with fluctuating volumes during peak usage periods, further complicates scalability, as systems must be designed to handle both expected and unexpected surges.
• Third-Party Limitations and Data Loss: Many third-party systems impose rate limits on API calls, which can restrict the volume of data an AI system can access or process within a given timeframe. These limitations often lead to incomplete data ingestion or delays in synchronization, impacting the overall reliability of AI outputs. Additional risks, such as temporary outages or service disruptions from third-party providers, can result in critical data being lost or delayed, creating downstream effects on AI performance.

Building AI Actions for Automation:

• API Research and Management: AI integrations require seamless interaction with third-party applications through APIs, which involves extensive research into their specifications, capabilities, and constraints. Organizations must navigate a wide variety of authentication protocols, such as OAuth 2.0 or API key-based systems, which can vary significantly in complexity and implementation requirements. Furthermore, APIs are subject to frequent updates or deprecations, which may lead to breaking changes that disrupt existing integrations and necessitate ongoing monitoring and adaptation.
• Cost of Engineering Hours: Developing and maintaining AI integrations demands significant investment in engineering resources. This includes designing custom solutions, monitoring system performance, and troubleshooting issues arising from API changes or infrastructure bottlenecks. The long-term costs of managing these integrations can escalate as the complexity of the system grows, placing a strain on both technical teams and budgets. This challenge is especially pronounced in smaller organizations with limited technical expertise or resources to dedicate to such efforts.

Monitoring and Observability Gaps

• Lack of Unified Dashboards: Organizations often use disparate monitoring tools that focus on specific components, such as data pipelines, model health, or API integrations. However, these tools rarely offer a comprehensive view of the overall system performance. This fragmented approach creates blind spots, making it challenging to identify interdependencies or trace the root causes of failures and inefficiencies. The absence of a single pane of glass for monitoring hinders decision-making and proactive troubleshooting.
• Failure Detection: AI systems and their integrations are susceptible to several issues, such as dropped API calls, broken data pipelines, and data inconsistencies. These problems, if undetected, can escalate into critical disruptions. Without robust failure detection mechanisms—like anomaly detection, alerting systems, and automated diagnostics—such issues can remain unnoticed until they significantly impact operations, leading to downtime, loss of trust, or financial setbacks.

Versioning and Compatibility Drift

• API Deprecations: Third-party providers frequently update or discontinue APIs, creating potential compatibility issues for existing integrations. For example, a CRM platform might revise its API authentication protocols, making current integration setups obsolete unless they are swiftly updated. Failure to monitor and adapt to such changes can lead to disrupted workflows, data loss, or security vulnerabilities.
• Model Updates: AI models require periodic retraining and updates to improve performance, adapt to new data, or address emerging challenges. However, these updates can unintentionally introduce changes in outputs, workflows, or integration points. If not thoroughly tested and managed, such changes can disrupt established business processes, leading to inconsistencies or operational delays. Effective version control and compatibility testing are critical to mitigate these risks.

About this directory

At Knit, we regularly publish guides and tutorials to make it easier for developers to build their API integrations. However, we realize finding the information spread across our growing resource section can be a challenge. 

To make it simpler, we collect and organise all the guides in lists specific to a particular category. This list is about all the HRIS API guides we have published so far to make HRIS Integration simpler for developers.

It  is divided into two sections - In-depth integration guides for various HRIS platforms and API directories. While in-depth guides cover the more complex APPs in detail, including authentication, use cases, and more, the API directories give you a quick overview of the common API end points for each APP, which you can use as a reference to build your integrations.

We hope the developer community will find these resources useful in building out API integrations. If you think that we should add some more guides or you think some information is missing/ outdated, please let us know by dropping a line to hello@getknit.dev. We’ll be quick to update it - for the benefit of the community!

   • Source: Getting Started With The API - BambooHR
2. What authentication method does the BambooHR API use?
   • Answer: The BambooHR API uses HTTP Basic Authentication. When making API requests, use the API key as the username and any random string as the password. Include these credentials in the 'Authorization' header of your HTTP requests.
   • Source: Getting Started With The API - BambooHR
3. Are there rate limits for the BambooHR API?
   • Answer: Yes, the BambooHR API enforces rate limits to ensure fair usage and system stability. If requests are deemed too frequent, the API may throttle them, resulting in a 503 Service Unavailable response. It's recommended to implement error handling in your application to manage such responses appropriately.
   • Source: Technical Overview - BambooHR
4. Can I retrieve employee data using the BambooHR API?
   • Answer: Yes, you can retrieve employee data using the BambooHR API. To get data for a specific employee, make a GET request to the endpoint /v1/employees/{id}/, where {id} is the employee's ID. You can specify which fields to retrieve by including a comma-separated list of field names in the fields query parameter.
   • Source: Get Employee - BambooHR
5. Does the BambooHR API support webhooks?
   • Answer: As of the latest available information, BambooHR supports two types of webhooks - global and permissioned. Global webhooks work on a subset of fields with open access while permissioned webhooks enable all fields but access is restricted via access control. You can also use third party service providers like Knit which provide virtual webhooks even for fields not supported natively by the BambooHR API for webhook functinality.‍
