delivery:
  signature: 'Signature verification follows the Standard Webhooks spec using three headers: `webhook-id` (unique message ID), `webhook-timestamp`
    (Unix timestamp of the attempt), and `webhook-signature` (HMAC‑SHA256 signature). A `signingSecret` is returned when the webhook endpoint
    is created and must be used to verify the signature.'
note: If the endpoint returns a non‑2xx status code or does not respond within 15 seconds, VideoGen retries delivery with exponential backoff.
  The `webhook-id` header can be used to deduplicate retries.
