description: CircleCI outbound webhooks deliver event notifications for workflow and job completions.
events:
- event: workflow-completed
  description: A workflow has reached a terminal state.
- event: job-completed
  description: A job has reached a terminal state.
delivery:
  auth: Optional secret token; each request includes a `circleci-signature` header containing a versioned HMAC‑SHA256 signature of the request
    body.
  signature: The `circleci-signature` header is a comma‑separated list of versioned signatures, e.g. `v1=...`. Only the latest version (v1) is
    used.
  retries: If the receiving server does not return a 2xx response or does not respond within 10 seconds, CircleCI will retry the delivery later.
