How we call your endpoint

  • Every event is an HTTP POST with a JSON body. The card at the top shows the method, headers, the answer we expect (any 2xx within 15 seconds) and the retries.
  • Sample payloads shows the fields of each event, ready for mapping.
  • Authentication shows exactly what each option sends, and how to check a signature.

Test and manage

  • Click Endpoints to open the panel. Pick an event next to an endpoint and click Send test: you see your endpoint's answer right away.
  • Edit changes an endpoint. For a signed endpoint it shows the signing secret with a Copy button.
  • Recent deliveries shows whether each call succeeded. Test calls are marked test.
  • An endpoint that fails 15 times in a row is paused. Fix it and click Enable.
  • Webhooks are for owners and admins.
