Documentation

Webhook Relay is a REST API for the parts of webhook delivery that feel solved until you ship. The docs are organized around the questions that actually come up in production:

• Quickstart — send your first event in 5 minutes.
• HMAC signing — how the X-Webhook-Signature header is built and verified.
• Idempotency keys — why the dedup window exists and how to use it.
• Retries + dead-letter — backoff schedule, circuit breaker, replay.
• Event filters — the "order.*" glob syntax.
• Receiver patterns — framework-specific handlers in TS, PHP, Python, Go.
