FAQ
What is a webhook tester?
A tool that gives you a unique URL which records every HTTP request sent to it. Point any service, script or form at the URL and inspect the method, headers, query string and body in real time.
How long does my URL work?
You get one personal URL per day. It lives for 24 hours and records up to 50 requests; the next day you automatically get a new one. Open the page in as many tabs as you like — it is the same URL everywhere.
Who can see my requests?
Anyone who knows the URL. Don't send real passwords, tokens or personal data.
Can I change the response?
Yes — open Response settings and set the HTTP status code, content type, headers, body and a delay your URL returns. Useful for testing timeouts and error handling.
How do I test webhook retries?
Set Fail the first N requests: the first N deliveries get an error status (500 by default), the next ones your normal response. You see every retry with its timing in the list.
Can I verify the webhook signature?
Yes. Open a request, paste your signing secret and press Verify. Stripe, GitHub, Shopify, Svix (Clerk, Resend) and plain HMAC-SHA256 signatures are checked right in your browser — the secret is never sent anywhere.
