Frequently Asked Questions
What is cURL used for?
cURL is a command-line tool used to transfer data to or from a server. Developers use it to test APIs, download files, and automate data transfer tasks.
Do I need to install cURL to use this?
No, this is a web-based builder that helps you *write* the command. To *run* the command, you need cURL installed on your computer (it comes pre-installed on macOS, Linux, and Windows 10/11).
How do I send JSON data?
Select POST or PUT as the method, then enter your JSON in the 'Request Body' tab. Our tool automatically formats it for the -d flag.
Can I add authentication headers?
Yes! Go to the 'Headers' tab and add a key of 'Authorization' with your value (e.g., 'Bearer YOUR_TOKEN').
Is my data safe?
Absolutely. All command generation happens in your browser. We do not store or transmit your API keys or request data to our servers.
What shell syntax is used?
The generated command uses standard Bash syntax, compatible with Linux, macOS, and Git Bash on Windows.
