What HTTP methods are supported?

GET, POST, PUT, PATCH, and DELETE are all supported.

Can I add custom headers?

Yes — use the Add Header button to add as many key/value header rows as you need.

How do I send a JSON body?

Switch to the JSON tab in the request body section and paste your JSON. The tool will automatically add the Content-Type: application/json header.

What authentication options are available?

None, HTTP Basic (username/password), and Bearer token are all supported.

Does this send a real request?

No — the tool only generates the command string. Copy it and run it in your own terminal.
