Zapier API reference: OpenAPI specs, endpoints, and schemas

This is the unified API reference for Zapier’s public APIs served from https://api.zapier.com. Select an API in the sidebar to browse its endpoints, schemas, authentication, and an interactive playground, all generated from the API’s OpenAPI spec.

Authentication

All Zapier public APIs are served from https://api.zapier.com. Most use OAuth 2.0: pass your access token in the Authorization: Bearer <token> header on every request. Some Workflow API endpoints use Client ID authentication instead.

Using the reference

Each API in the sidebar includes an interactive playground where you can make live requests. Select an endpoint, fill in the parameters, and run it directly from the browser.
