Test a webhook online — free, no signup

Building or debugging a webhook? Get a unique URL in one click, point your webhook at it, and see every request — method, path, headers, and body — exactly as it arrived.

• No signup. One click (or one curl) gives you a live URL and a read token.
• See everything. Full method, path, query string, headers and raw body, newest first.
• Automate it. A real JSON API means your CI pipeline or test suite can assert on the payload, not just eyeball it.
• Safe. Catchr only receives — it never re-sends your requests anywhere.

# one call, no signup
curl -s -X POST https://catchr.perch-app.workers.dev/api/bins
# → {"id":"a1b2c3d4","url":"https://catchr.perch-app.workers.dev/h/a1b2c3d4","token":"…"}
# send anything to the url, then read it back:
curl "https://catchr.perch-app.workers.dev/api/bins/a1b2c3d4/requests?token=…"

How to test a webhook in three steps

1. Get a URL. POST /api/bins (or click the button above) returns a live capture URL and a read token — instantly, no account.
2. Point your webhook at it. Paste the URL into Stripe, GitHub, Shopify, Twilio, a Zapier/n8n step, or your own code, and trigger the event.
3. Inspect what arrived. Open the live inspector or call GET /api/bins/:id/requests?token=… to read the exact method, headers (signatures, auth), query and raw body.

Because reading is a plain JSON call, the same flow drops straight into a test: fire the webhook, then assert that the signature header and payload are what you expect — no staging server, no ngrok tunnel.
