Why use a temporary bin
Webhook Tester creates a temporary request bin and gives you a public receive URL when the separate bin service is available. A webhook sender can call that URL while you inspect the captured requests on this page.
Each captured entry shows the HTTP method, path, receive time, size, content type, allowed headers, and body text. The source defines a two-hour lifetime, a 50-request cap, a 64 KiB body limit, and selected header redaction. Anyone with the bin id can inspect the requests.
Use synthetic data and remove the receive URL when the test ends. Use the HTTP Request Builder to send a controlled request, or inspect browser network evidence with the HAR Viewer.
How it compares
A request bin gives you a public receive URL without a local server or tunnel. It is useful for short capture tests, but it does not replace permanent logs, request replay, handler execution, or provider-specific signature verification.
A local tunnel tests your real application code, while FindUtils shows a limited stored request record. Use the HAR to cURL tool when the starting point is a browser archive instead of an incoming webhook.
Webhook Testing Tips
- Treat the bin id and receive URL as secrets because either can expose captured request data.
- Use test payloads. Do not send passwords, access tokens, payment details, or personal records.
- Keep the raw body unchanged when you test a signature because whitespace can affect the digest.
- Use a slower refresh interval when events arrive rarely, or turn polling off after the request arrives.
- Remove the temporary receive URL from the provider when your test ends.
