Webhooks
Retry Logic
Build resilient webhook consumers with idempotency and dead-letter handling.
Overview
Webhook delivery can be retried when your endpoint is unavailable. Design handlers that are safe to execute multiple times.
What You Will Learn
- Expected retry behavior on non-2xx responses.
- Idempotency keying with delivery IDs.
- Alerting and replay workflows for failed deliveries.
Implementation Checklist
- Process each event exactly once using a unique delivery store.
- Return 2xx immediately after durable persistence.
- Set up alerts for repeated delivery failures.
