How does CanHook work?

Three steps from zero to inspecting live webhooks.

1

Create a catch URL

Generate a unique endpoint like /h/abc123. It accepts any HTTP method — GET, POST, PUT, anything.

2

Point your service at it

Set your webhook URL in Stripe, GitHub, Shopify, or any service to your CanHook catch URL.

3

Inspect & relay

Watch requests arrive live. Inspect payloads, replay them, and forward to your real endpoints with transforms.

Everything you need to debug webhooks

✓Instant webhook catch URLs
✓Live payload inspector with syntax highlighting
✓Full request capture (headers, body, query, source IP)
✓Replay captured webhooks to any URL
✓Search and filter over request history
✓Webhook relay & forwarding to multiple destinations
✓Payload transforms (template, filter, passthrough)
✓Automatic retries with delivery logs
✓SSRF-protected destinations

Common questions about webhook testing and CanHook.

A webhook catcher URL is a unique endpoint (like https://canhook.com/h/abc123) that accepts any incoming HTTP request and records it so you can inspect exactly what a service sent — headers, body, method, and more — without writing any server code.
Create a free CanHook endpoint, point the sending service at your catch URL, and every request appears in a live dashboard where you can view the pretty-printed JSON, raw body, headers, and query string, then replay or search them.
Set your Stripe webhook endpoint to your CanHook catch URL, trigger a test event from the Stripe dashboard, and CanHook captures the full signed payload so you can inspect the event structure before wiring it into your app.
On a paid plan, add relay rules to an endpoint. Each rule forwards the captured webhook to a destination URL, optionally transforming the payload, with automatic retries and per-destination delivery logs — so one inbound webhook fans out to many services.
Point the service at a CanHook catch URL. If requests appear in CanHook but not your app, the problem is downstream; if nothing appears, the sender isn't delivering — CanHook isolates exactly where the webhook is being lost.
Yes — CanHook's free tier gives you catch URLs, a live payload inspector, request history, and replay at no cost, with no credit card required.
