Full list of Knit's ATS API Guides

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 ATS API guides we have published so far to make ATS Integration simpler for developers.

It is divided into two sections - In-depth integration guides for various ATS platforms and ATS 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 If you think that we should add some more guides or you think some information is missing/ outdated, please let us know by dropping a line to hello@getknit.dev.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!

About Knit

Knit is a Unified API platform that helps SaaS companies and AI agents offer out-of-the-box integrations to their customers. Instead of building and maintaining dozens of one-off integrations, developers integrate once with Knit’s Unified API and instantly unlock connectivity with 100+ tools across categories like CRM, HRIS, ATS, Accounting, E-Sign, and more.

Whether you’re building a SaaS product or powering actions through an AI agent, Knit handles the complexity of third-party APIs—authentication, data normalization, rate limits, and schema differences—so you can focus on delivering a seamless experience to your users.

Build once. Integrate everywhere.
