How do I test an HTTP API?

Enter the API URL, select the HTTP method (GET, POST, PUT, etc.), add any headers or body if needed, and click Send. The response will appear below with status code, headers, and body.

Why am I getting a CORS error?

Browsers enforce the Same-Origin Policy. If the API server does not include CORS headers (Access-Control-Allow-Origin), the browser will block the response. This is a browser limitation, not an issue with the tool.

Can I send POST requests with a JSON body?

Yes. Select POST as the method, go to the Body tab, choose JSON as the content type, and enter your JSON data in the text area. The Content-Type header will be set automatically.

What is the request timeout?

Requests have a 30-second timeout. If the server does not respond within 30 seconds, the request will be cancelled and a timeout error will be displayed.
