A generic webhook channel delivers event payloads to your HTTPS endpoint as things happen: incidents, maintenance, and monitor signals.
What you receive
- A JSON envelope with a stable shape and a
schema_version. - Signature headers so you can verify the request came from Fajita.
- At-least-once delivery, so design your endpoint to be idempotent.
