# CanHook

> CanHook is a developer tool to catch, inspect, and relay webhooks: instant catch URLs with a live payload inspector, plus a paid relay pipeline that transforms and forwards webhooks to multiple destinations with retries.

CanHook helps developers debug and route webhooks. The free tier provides unique catch URLs (https://canhook.com/h/{token}) that capture any HTTP request — method, headers, raw body, parsed JSON, query string, source IP — and display it in a live dashboard with replay and search. The paid tier adds a relay pipeline that forwards captured webhooks to one or more destinations with payload transforms (template, filter, passthrough), custom headers, automatic retries, and delivery logs. Relay destinations are protected against SSRF (private and reserved IP ranges, including cloud metadata endpoints, are blocked).

## Common questions

- What is a webhook catcher URL? A unique endpoint that records any incoming HTTP request for inspection.
- How do I test a Stripe webhook? Point Stripe's webhook endpoint at your CanHook catch URL and trigger a test event.
- How do I forward a webhook to multiple URLs? Add relay rules (paid) to fan out one webhook to many destinations with retries.
- Is there a free webhook testing tool? Yes — CanHook's free tier includes catch URLs, a live inspector, history, and replay.
