Frequently asked questions
What is cURL for?
It is the most used command-line tool to test APIs: it makes HTTP requests with any method, header and body, and comes installed on macOS, Linux and Windows 10 or newer.
How do I send JSON in the body?
Choose POST, PUT or PATCH, paste the JSON in the body and pick the JSON type. The tool adds the Content-Type: application/json header and uses --data-raw with single quotes, the way it works in the terminal.
Does it work on Windows?
The commands use single quotes, which work on macOS, Linux, Git Bash and WSL. In the Windows Command Prompt (cmd) you need double quotes; check the Windows (cmd) option for that.
