Frequently Asked Questions

What is cURL?▾
cURL is a command-line tool and library for transferring data using URLs. It supports HTTP, HTTPS, FTP, SMTP, and many other protocols. Developers use it to test APIs, debug HTTP requests, download files, and script web interactions. Browser DevTools can copy any request as a cURL command, making it a universal way to share HTTP request details across teams and tools.
How does the -H flag work in cURL?▾
-H (or --header) adds a custom HTTP header to the request. Multiple -H flags add multiple headers. Example: curl -H "Content-Type: application/json" -H "Authorization: Bearer token" https://api.example.com. Headers are case-insensitive per HTTP spec, but servers may be case-sensitive in practice. Common headers: Authorization, Content-Type, Accept, X-API-Key, User-Agent.
What is -d or --data in cURL?▾
-d (--data) sends data in the request body, implicitly setting the method to POST. --data-raw sends the data as-is without URL-encoding. --data-binary preserves binary data including newlines. -d "@file.json" reads the body from a file. For JSON: curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' https://api.example.com.
What is -u in cURL?▾
-u (--user) adds HTTP Basic Authentication. Format: -u "username:password". cURL encodes this as a Base64-encoded Authorization header: "Authorization: Basic base64(username:password)". For Bearer token auth, you would use -H "Authorization: Bearer TOKEN" instead. The -u flag is shorthand that cURL converts to the Authorization header automatically.
How do I handle cookies in cURL?▾
-b "name=value" sends a cookie with the request. -c cookiejar.txt saves received cookies to a file. -b cookiejar.txt reads cookies from a file (combine with -c for session persistence). For multiple cookies: -b "session=abc; user=123". Browser DevTools's "Copy as cURL" includes all cookies that were sent with the original request, making it easy to reproduce authenticated sessions.
