cURL Builder
Generate cURL commands from HTTP request parameters. Free online developer tool for fast browser-based work.
What is this tool?
cURL Builder turns request details into a command that can be shared, repeated and pasted into a terminal. It is useful for API debugging, QA handoffs and documentation examples.
How to use
- Enter the method, URL, headers and body for a safe test request.
- Generate the command and inspect whether quoting, JSON and headers look correct.
- Redact tokens before sharing the command in tickets, docs or chat.
curl -X GET \ 'https://api.example.com/v1/resource' \ -H 'Content-Type: application/json' \ -H 'Authorization: Bearer TOKEN'
Practical example
A good cURL example lets another person reproduce a request without guessing hidden setup.
curl -X POST "https://api.example.test/orders" \
-H "content-type: application/json" \
-d '{"requestId":"generated-uuid","status":"draft"}'API
Pair cURL examples with API Docs so endpoints, parameters and response shapes remain easy to verify.

Privacy
Do not paste production bearer tokens, cookies, private URLs or customer payloads. Use placeholders and staging endpoints.
Frequently asked questions
What makes a useful cURL example?
It includes method, endpoint, safe headers, body shape and expected context without exposing secrets.
Should I include Authorization headers?
Use placeholders such as Authorization: Bearer <token> rather than real credentials.
Can cURL replace API tests?
No. It is excellent for reproduction and documentation, while automated tests should live in your test suite.
Limitations / when not to use
A cURL command can expose secrets if headers or URLs include tokens. Redact authorization headers and private query parameters before sharing.
