About cURL

cURL (Client URL) is a command-line tool and library for transferring data with URLs. It is available on all major operating systems and is the most widely used tool for making HTTP requests from the command line, shell scripts, CI/CD pipelines, and automated testing. Understanding how to build cURL commands is an essential skill for API development and DevOps.

This generator creates syntactically correct cURL commands with all your specified options — method, headers, authentication, request body, and flags. The generated command can be copied and run directly in any terminal. It also serves as a reference for converting API calls from GUI tools to reproducible command-line invocations.

FAQ

How do I add Bearer token auth to cURL?
Add the Authorization header: curl -H "Authorization: Bearer YOUR_TOKEN" https://api.example.com. You can also use the -u flag for Basic auth: curl -u username:password https://api.example.com.
How do I send a JSON body with cURL?
Use -X POST -H "Content-Type: application/json" -d '{"key":"value"}'. The -d flag sets the request body. On Windows, use double quotes and escape the inner quotes: -d "{\"key\":\"value\"}".
