Need something Expensify's pre-built connector doesn't cover?

Describe the extra endpoint you need — the Agent researches it via a live web search (or works from docs you hand over) and extends Expensify's connector on demand.

Not a block library. Real code.

Legacy automation tools like Zapier, Workato, and Make hand you a fixed library of pre-built steps to drag, drop, and configure around the edges. Knit's Integrations Agent writes real, custom Expensify integration code for your exact logic.

Legacy iPaaS

  • Fixed library of pre-built steps — drag, drop, configure around the edges
  • Capped by whatever the vendor's already built
  • AI features bolted on after the fact

Knit Integrations Agent

  • Real, inspectable code for your exact Expensify logic
  • Auto-builds a missing Expensify connector itself
  • Native LLM connectors built in, not bolted on
Prompt "When an employee joins in Hibob, create an expense user account for them in Expensify."
from knit import Knit

client = Knit(api_key=KNIT_API_KEY)

@client.on("new-report")
def create_expense_report(event):
    return client.expense_management.create_expense_report(
        integration_id=EXPENSIFY_INTEGRATION_ID,
        record_id=event["id"],
        fields={
            "source": "Expensify",
            "synced_at": event["updated_at"],
        },
        # ...maps the event to a real "Create Expense Report" call
    )

Example: illustrative of what the Agent generates from a plain-English prompt — real, inspectable, and yours to edit.

Easy to integrate. Knit's dashboard is intuitive for setting up and testing integrations, and the sandbox is extremely useful during development.

Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

FAQ

Common questions about Expensify integrations

Is there a pre-built Expensify connector?

Yes — Expensify is already live in Knit's Unified API/MCP Servers catalog. This page is about what you can build with it (integrations and automations), not the technical API coverage itself — see the Expensify product page for that.

How do I build a custom Expensify automation?

Describe what you want above and the Integrations Agent builds it, using Expensify's existing connector or researching further API surface as needed.

Which apps does Expensify pair well with?

See the popular integrations above — real automations already live, plus more the Agent can build on demand.

How long does a new automation take to build?

Minutes to build a first working version, not weeks — you test it against real Expensify data before it goes anywhere near production.
