Prerequisites

Before you begin, make sure:
  • You have access to a public Zapier integration.
  • You’ve registered your app and authenticated to use the API.
  • You have at least one action configured in your integration, with required fields and sample data tested in the Zapier UI or via the API.
To trigger an action, make a POST request to /v2/action-runs/
Important: Before every action run, for the action attribute on your request body you should retreive a new/unique id from the Get Actions endpoint for the action that you’d like to execute. This ensures that the action run can be uniquely tracked, that it can be properly debugged, and that attributions are properly reported.Note: The id attribute will be unique for every lookup on the Get Actions endpoint, and the key attribute will be the action’s consistent developer-provided identifier.
