Quick Reference
Webhooks: Sign payloads with HMAC-SHA256, verify with timing-safe comparison. Include timestamp to prevent replay attacks (5 min tolerance). Use idempotency keys to prevent duplicate processing. Retry with exponential backoff (5 attempts). Return 2xx quickly, process async.
Use When
- Event-driven integrations
- Third-party notifications
- Real-time data sync
- Payment processing callbacks
Skip When
- Synchronous APIs
- Internal service calls
