About Build a cURL Command Without Postman

curl is the near-universal command-line tool for making HTTP requests, used constantly for testing APIs, debugging network issues, and scripting requests outside of a browser or full application code. Its syntax, while powerful, isn't especially memorable — remembering the exact flags for setting a request method, adding multiple headers, and including a JSON body correctly (with the right quoting so your shell doesn't mangle special characters) is a recurring small friction point even for experienced developers.

This tool builds a correct curl command for you from a simple form: pick an HTTP method, enter a URL, add any headers you need (one per line, in the standard `Key: Value` format), and provide a request body if your method needs one. It handles the fiddly syntax details automatically — wrapping the URL and header values in quotes, adding the `-X` flag for the method, using `-H` for each header, and `-d` for the body — producing a command you can paste directly into a terminal and run immediately.

This is especially useful for sharing a reproducible API request with a teammate (pasting a working curl command is often clearer and more portable than describing a request in prose), documenting exact API usage in a README or ticket, or just double-checking you have the right flag syntax before running something against a production API where a typo could have real consequences.

The generated command uses standard curl syntax compatible with any modern terminal on macOS, Linux, or Windows (via PowerShell, WSL, or Git Bash) — curl ships built into macOS and most Linux distributions by default, and has been included in Windows 10 and 11 since 2018, making a generated command broadly usable regardless of what system you or a teammate is running.

How it works

  1. Choose a method and enter the URL. Pick GET, POST, PUT, PATCH, or DELETE, and enter the endpoint URL.
  2. Add headers and a body if needed. Enter headers one per line, and a request body for non-GET methods.
  3. Copy the generated command. A ready-to-run curl command is built instantly and ready to paste into a terminal.

Examples

Generating a POST request

Input

Method: POST, URL: https://api.example.com/users, Body: {"name":"Jane"}

Output

curl -X POST 'https://api.example.com/users' \
  -H 'Content-Type: application/json' \
  -d '{"name":"Jane"}'
