cURL Command Builder
Typing curl flags from memory is error-prone — the flag order, quoting around a JSON body, the Content-Type header that POST needs but GET does not. This generator assembles a correctly formatted, multi-line curl command from three choices so you can paste it straight into a terminal. Three inputs control the output: the HTTP method, the URL, and a Send bearer token checkbox. When checked, the command adds Authorization: Bearer $TOKEN using a shell variable. For write methods (POST, PUT, PATCH) it adds Content-Type: application/json and a sample JSON body. All methods include Accept: application/json. The command uses backslash line continuations for readability. Replace the placeholder URL, set TOKEN with export TOKEN=yourvalue, and swap the sample body with your real fields. The multi-line format is also useful in a README or bug report as a reproducible request example.

Detailed instructions
- Choose the HTTP method.
- Paste the endpoint URL.
- Toggle the bearer token if the endpoint needs auth.
- Copy the command and replace the placeholder body.
Use Cases
- •Testing an API endpoint quickly from the terminal
- •Sharing a reproducible request in a bug report
- •Smoke-testing an endpoint before writing client code
- •Remembering the right headers for a POST or PUT
- •Teaching teammates how to call an API with curl
Tips
- →Export your token as $TOKEN so secrets stay out of shell history.
- →Add -i to inspect response headers when debugging.
- →Use -sS to silence the progress bar but keep errors visible.
- →Pair it with the API documentation snippet generator for full docs.
FAQ
does it include a bearer token header
Only if the Send bearer token checkbox is checked. When enabled, an Authorization: Bearer $TOKEN header is added. The token is read from a shell variable called TOKEN, so you run export TOKEN=yourvalue in the terminal rather than pasting the secret into the command.
when does it include a request body
For POST, PUT, and PATCH only — those methods also receive a Content-Type: application/json header. GET and DELETE receive no body or Content-Type. Replace the sample body fields with your real request payload.
will the command run in any terminal
The command uses standard curl flags and POSIX backslash line continuation, so it runs in bash, zsh, and most Unix shells. On Windows, use it in WSL or Git Bash. PowerShell requires different quoting rules and line continuation characters.
how do I add extra headers or query parameters
Manually add -H "Header-Name: value" for each additional header and append query parameters directly to the URL string. The generator produces the most common headers; extend the command before running it.
