📖 What is cURL Command Generator?
cURL Generator builds cURL commands visually. Set the HTTP method, URL, headers, request body, authentication and other options, and get a ready-to-paste cURL command. Use it to prototype API requests, share reproducible API calls with teammates, or convert API documentation into testable commands. Everything runs in your browser.
💡 Example
Input
Method: POST
URL: https://api.example.com/users
Header: Content-Type: application/json
Body: {"name":"Alice"}
Output
curl -X POST https://api.example.com/users \
-H "Content-Type: application/json" \
-d '{"name":"Alice"}'
🛠️ Common Use Cases
- Building API requests from documentation for testing
- Sharing reproducible API calls with teammates
- Prototyping requests before writing code
- Generating cURL commands for CI/CD pipeline scripts
- Converting Postman requests to cURL format
📝 Common cURL Options
-X METHOD — HTTP method (GET, POST, PUT, DELETE)-H "Header: Value" — add a request header-d 'body' — request body data-u user:pass — basic authentication-k — skip SSL verification (for testing only)-v — verbose output (shows headers)-o file — save response to file
⚠️ Common Mistakes
- Forgetting Content-Type — POST/PUT requests with JSON need
-H "Content-Type: application/json" - Quote handling — use single quotes around the body to avoid shell escaping issues with JSON double quotes
- Using -d with GET — GET requests should use query parameters in the URL, not a request body
