Webhooks close the media loop - if you treat them carefully.
A render API that only polls will hurt product UX. Signed, retry-safe webhooks let your backend mark jobs terminal and publish artifacts without busy-waiting.

- Deduplicate delivery IDs.
- Make handlers idempotent against duplicate terminal events.
- Still verify artifact checksums before user-visible publish.
