Key considerations
- ✓Sign webhook payloads with HMAC — receivers need to verify authenticity
- ✓Implement exponential backoff retries (1min, 5min, 30min, 2hr, 24hr)
- ✓Log all delivery attempts for debugging
- ✓Support webhook endpoint verification (challenge-response)
- ✓Make webhook processing idempotent — events may be delivered more than once
Common mistakes
- ✗No retry logic (webhooks fail silently)
- ✗Not signing payloads (security risk)
- ✗Synchronous webhook delivery (blocks your API)
- ✗No delivery logging (impossible to debug failures)
- ✗Not handling duplicate deliveries (idempotency)
