Does this send the request?

No. This only builds the command text. Copy it and run it in your own terminal, or paste it into a tool that executes curl commands.

How are special characters handled?

URLs, header values, and body content are wrapped in single quotes with any embedded single quotes escaped, so the command is safe to paste into a POSIX shell.

What is the difference between raw, JSON, and form body types?

Raw sends your text as-is with --data. JSON does the same but also adds a Content-Type: application/json header. Form builds an application/x-www-form-urlencoded body from your key/value rows.

Why does GET not show a body option effect?

curl still accepts --data with GET, but most APIs ignore a GET body. Switch to POST, PUT, or PATCH if you need the server to read it.

Are query parameters URL-encoded?

Yes. Each key and value you add as a query parameter is percent-encoded before being appended to the URL.

Summary

Fill in method, URL, headers, and body to get a ready-to-paste curl command.

How it works

Pick the HTTP method and enter the target URL.
Add query parameters as key/value rows; they are appended and encoded onto the URL.
Add header rows for things like Authorization or Content-Type.
Choose a body type (none, raw, JSON, or form) and fill in the content.
Copy the generated command from the preview panel.

Use cases

Turn an API endpoint and a few headers into a runnable curl command.
Prototype a POST request with a JSON payload before writing client code.
Share a reproducible request with a teammate or in a bug report.
Build a form-encoded login request without hand-escaping ampersands.
Quickly test an endpoint that needs a bearer token header.
