Key points

  • Eliminate polling loops for long-running AI jobs (Batch API, Deep Research, video generation) with automatic HTTP POST notifications upon completion.
  • Two configuration modes: Static webhooks (HMAC-secured) for project-level global integration, and Dynamic webhooks (JWKS-signed) for request-level routing.
  • Every webhook is cryptographically signed per the Standard Webhooks spec; reject payloads older than 5 minutes to prevent replay attacks.
  • Thin payloads carry status pointers (e.g., output_file_uri) instead of raw data; use webhook-id for deduplication of at-least-once deliveries.
