Frequently Asked Questions

What is an HTTP request?

An HTTP request is a message sent from a client (browser, app, or script) to a server, asking it to perform an action. It includes a method (GET, POST, etc.), a URL, optional headers, and an optional body.

What is the difference between GET and POST?

GET requests retrieve data and should not change server state. GET parameters go in the URL. POST requests submit data (in the request body) and are used to create or update resources.

What is a Bearer token?

A Bearer token is an access token used for API authentication. It is sent in the Authorization header as "Authorization: Bearer your-token-here". Most modern APIs use Bearer tokens for authentication.

What is Basic authentication?

Basic auth sends a username and password encoded in Base64 in the Authorization header. It should always be used over HTTPS. The format is "Authorization: Basic base64(username:password)".

Why does the tool generate multiple code formats?

Different developers use different tools and languages. Generating cURL, JavaScript fetch, Python requests, and PHP curl from the same request definition saves time and eliminates transcription errors.

Is my API key or token private?

Yes. All code generation happens in your browser. Nothing you enter is ever sent to our servers. However, never share generated code that contains real API keys — redact them before sharing.
