A webhook tester is a tool that gives you a temporary public URL you can paste into any service (Stripe, GitHub, Shopify, Zapier, custom APIs) so that when that service fires a webhook, you can actually see what it sent — headers, body, query params, everything — without writing a single line of receiver code.
Why developers need it
- Debug integrations faster. Instead of guessing why your endpoint is failing, inspect the exact payload a third-party service is sending.
- No local setup. No
ngrok, no tunnels, no server. Just a public URL. - Verify payload structure. Confirm the shape of the JSON, the headers, the content-type — before you write your handler.
- Reproduce bugs. Replay the exact request to test fixes repeatedly.
How to use it (3 steps)
- Generate a URL. Click one button — you get a unique webhook endpoint like
https://online-webhooks.com/webhook/<id>. - Send requests to it. Paste the URL into your service (Stripe dashboard, GitHub webhook settings, your own code, a
curlcommand). - Inspect the payload. Every incoming request appears instantly in the UI with method, headers, query, and body — pretty-printed and collapsible like a real JSON editor.
Benefits
- ✅ No login, no signup — open the page, get a URL, start testing.
- ✅ Instant URL generation — a fresh endpoint in under a second.
- ✅ Replay any request — re-record the last received payload with one click.
- ✅ Supports every content type — JSON, form-encoded, plain text, raw bodies.
- ✅ Saved endpoints — your generated URLs persist locally so you can come back.
Perfect for debugging
Stripe, GitHub, Shopify, Zapier, Twilio, Slack, Discord, custom REST APIs — anything that can POST to a URL.
