description: Danube Data provides a webhook receiver example that expects events with a JSON body containing an "id" and a "kind" field.
events:
- event: demo.created
  description: An event indicating that a demo resource has been created; the payload must include an "id" string and a "kind" equal to "demo.created".
delivery:
  auth: Requests are authenticated with an HMAC‑SHA256 signature. The sender includes a timestamp header `x-demo-timestamp` and a signature header
    `x-demo-signature` which is the hex‑encoded HMAC of "<timestamp>." concatenated with the raw request body, using a secret of at least 24 characters.
  signature: x-demo-signature
  retries: If the receiver cannot store the event it returns HTTP 503, allowing the sender’s retry policy to attempt delivery again. Successful
    inserts return HTTP 202; duplicate event IDs are ignored (idempotent).
