Frequently asked questions
How does the webhook tester work?+
Click to generate a unique temporary URL, then point any service at it. Incoming requests appear in the inspector within a few seconds (the page polls automatically), showing the method, headers, query parameters, body, content type, and timestamp for each one. You can also fire built-in GET and POST test requests to see it in action.
How long does my webhook URL last?+
Each session lasts 24 hours. After it expires, the URL stops accepting requests and the session with all captured requests is deleted. You can also destroy the session yourself at any time, or generate a fresh URL whenever you need one.
Is the captured data private?+
Captured requests are stored temporarily on our server so the inspector can display them, and the random session ID in the URL is the only access control — anyone who has your exact URL could view its requests. Do not send production secrets, API keys, or personal data to a test inbox, and destroy the session when you are done.
Which HTTP methods can I test?+
GET, POST, PUT, PATCH, and DELETE are all captured and color-coded in the request list. JSON, form data, query strings, and custom headers are recorded so you can inspect exactly what a service sends.
Can I use it to build n8n, Make, or Zapier automations?+
Yes — that is the main use case. Paste the URL as the HTTP/webhook target in your automation, trigger it, and inspect the exact payload structure before writing your parsing logic. It also works for testing Stripe-style webhook senders, form submissions, or any service that fires HTTP callbacks.
Is the webhook tester free?+
Yes. It is free and requires no account — sessions are anonymous and tied only to the generated URL in your browser.
