How-to

Set up media job webhooks without runaway polling.

Webhooks keep your product responsive without making every browser or server sit in a tight loop. Treat them as signed, retryable events and make your handler boringly idempotent.

Steps

1. Register a server endpoint you control, not a browser callback.
2. Verify the delivery signature and timestamp before trusting the body.
3. Deduplicate delivery IDs and make terminal-state handling safe to repeat.
4. Fetch or publish artifacts only after validating content type and checksum.
5. If you add a fallback poller, use one in-flight request, cancellation, timeout, capped exponential backoff, jitter, and stop it when it is no longer needed.
