Guide
Treat webhook retries as the normal path.
Signed webhooks will retry. Your handler must verify signatures, dedupe delivery IDs, and stay idempotent against duplicate terminal events — then still checksum the artifact.
- Verify signature + timestamp window.
- Deduplicate delivery IDs before side effects.
- Use user-triggered or bounded fallback refresh — not a forever poller. See AGENTS.md polling rules in the repo and webhook how-to.
- Publish only after artifact verification.
