Can it test APIs that require authentication?

Yes, you can add Authorization headers such as Bearer tokens, API keys, or Basic Auth in the Headers section before sending the request.

Does it support all HTTP methods?

Yes, GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS are all supported. Select the method from the dropdown before sending.

Why does my request fail with a CORS error?

CORS errors occur when the API server does not allow requests from browser origins. APIs designed for server-to-server calls typically block browser requests. Use a server-side proxy or test APIs that support browser CORS.

Can I send JSON in the request body?

Yes, select the POST, PUT, or PATCH method, add a Content-Type: application/json header, and paste your JSON body in the Body field.
