Overview
Webhook systems fail when they treat delivery as fire-and-forget — sending events without tracking delivery success or implementing retry on failure. A consumer whose endpoint is temporarily unavailable loses every event during that window with no way to recover. Reliable webhooks require at-least-once delivery semantics, idempotent event handling guidance for consumers, and a delivery log that makes failed deliveries visible and retryable.
The Webhooks Design Framework implements reliable delivery with retry semantics, signature verification that prevents spoofed events, and the consumer registration and management interface that makes webhooks debuggable.
