Frequently Asked Questions

What HTTP methods are supported?

GET, POST, PUT, PATCH, and DELETE. Each method has appropriate body handling - GET requests don't include a body, while POST/PUT/PATCH support JSON, form data, and raw text bodies.

Does this work with any API?

It works with any publicly accessible API. For APIs with CORS restrictions, requests are proxied through a server-side route. Authentication headers (Bearer tokens, API keys) are supported.

Can I send request bodies?

Yes. For POST, PUT, and PATCH requests, you can compose JSON bodies with syntax highlighting, form-encoded data with key-value pairs, or raw text with a custom Content-Type header.

How do I test an API endpoint that needs a bearer token?

Add an Authorization header with the value Bearer followed by your token, set the method and body, then send. The tool returns the status code, response headers, and formatted body so you can confirm the auth worked.
