description: ImageStep webhooks deliver job-level events. Up to 10 endpoints per account can be registered. Each delivery is a POST with a JSON
  body and signed headers.
events:
- event: job.completed
  description: Emitted when a job finishes successfully.
- event: job.failed
  description: Emitted when a job finishes with a failure.
delivery:
  signature: 'ImageStep-Signature: t=<unix seconds>,v1=<hex HMAC>'
  content_type: application/json
note: The HMAC is computed as HMAC‑SHA256("<t>.<raw request body>", secret) using the secret returned at endpoint creation (the whsec_ prefixed
  value). The same secret is used for all retries of the same event, and the timestamp is refreshed on each retry.
