HTTP Request (cURL) Builder

About this tool

Compose an HTTP request visually and get a ready-to-run curl command. Choose the method, URL, headers and body, then copy the command.

Example

Input: POST + URL + body

Output: curl -X POST "..." -d ...

Privacy

This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.

How to use this tool

1. Pick the HTTP method you want, such as GET or POST.
2. Enter the full request URL, including the scheme like https://.
3. Add any headers you need, then paste or type the request body if the method uses one.
4. Copy the generated curl command and run it in your terminal.

Step by step, what happens

1. The tool takes the method, URL, headers, and body you provide in the visual form.
2. It turns those fields into a curl command with the right flags and quoting.
3. It keeps your headers and body in the command so the request can be reproduced outside the browser.
4. You copy the finished command and use it directly in your shell.

Worked example

Here is a simple POST request that sends JSON to a test API endpoint.

Input: POST https://api.example.com/users Content-Type: application/json {"name":"Ava"}

1. Select POST and enter the URL https://api.example.com/users.
2. Add the Content-Type header and paste the JSON body.
3. The tool builds a curl command that includes the method, header, and request data.
4. Copy the command and run it in your terminal.

Tips and common mistakes

• Always include the full URL, not just the path, or the command will not know where to send the request.
• Use headers exactly as the server expects, especially Content-Type and Authorization.
• If you paste JSON into the body, make sure it is valid and that quotes are preserved in the generated curl command.
• Some methods, like GET, usually do not need a body, so leave it empty unless the API specifically requires one.
