Questions fréquentes

Quick answers.

Why did my request fail with a CORS error?

Web browsers prevent scripts from making requests to a different domain unless the server sends specific permissive headers. You may need to enable CORS on your server or use a browser extension to bypass this security feature during testing.

Are my API keys or secrets stored?

No. All request details stay within your browser's local state. We do not log, persist, or transmit your headers or authentication tokens to our own servers.

Which HTTP methods are supported?

The tool supports all standard methods including `GET`, `POST`, `PUT`, `PATCH`, `DELETE`, `HEAD`, and `OPTIONS`. You can manually toggle these in the method dropdown.

Can I send JSON payloads?

Yes. Select the `POST` or `PUT` method, set the `Content-Type` header to `application/json`, and enter your raw data into the body field.
