How to use the Request Snippet Generator

Build a clean HTTP request snippet from a URL, method, headers, and JSON body — then export to cURL, Postman, fetch, Axios, Node.js, Python requests, Go, Java, Ruby, PHP, or PowerShell. Useful for documenting an API, creating a reproducible request recipe for a bug report, or porting an example between languages. Runs locally; URL, headers, and body never leave your browser.

What it does

Inputs: URL, method (GET / POST / PUT / PATCH / DELETE / OPTIONS), headers, JSON body, auth (Bearer / Basic / API key).
Outputs: cURL, Postman, fetch, Axios, Node.js (https / node-fetch), Python requests, Go, Java (HttpClient), C#, Ruby, PHP, PowerShell.
Validates JSON body and pretty-prints; preserves nested structure in output.
Handles form-encoded bodies, multipart uploads, and query parameters.
Reverse direction: paste a cURL command to populate the form (use the dedicated cURL Converter for that flow).

When to use it

Document an API endpoint with code samples in multiple languages.
Create a copy-paste-ready request for a bug report or ticket.
Hand off an API call from frontend to backend in a different language.
Convert a documentation example into an executable command.
Generate a Postman request from a known URL + body without manual entry.
Test an integration without writing throwaway code.

How to use it

Enter the URL and HTTP method.
Add headers as key/value pairs (Content-Type, Authorization, etc.).
Paste a JSON body or form-encoded body if your method has one.
Pick the target language / tool — cURL, fetch, Python, Go, Postman, etc.
Copy the snippet straight into your terminal, code, or Postman collection.
For a cURL command as input, use the cURL Converter; for OpenAPI sources use the OpenAPI Snippet Extractor.

Tips & pitfalls

Set Content-Type: application/json when sending a JSON body — some servers default to text/plain otherwise.
For browser fetch, account for CORS — the request that works from the terminal may not work from the browser without server CORS support.
Mask Authorization in any snippet you paste publicly — rotate the token if it leaks.
Use form encoding (application/x-www-form-urlencoded) only when the server expects it; default to JSON for modern APIs.
Multipart uploads vary across libraries — verify the generated snippet matches your server's expectation.

FAQ

How do I generate a Postman snippet? Pick Postman as the output target — the snippet is a request you can paste into the Import dialog.
How do I generate a cURL command from a JSON body? Fill the form, pick cURL, and copy the generated command.
Can I generate code in multiple languages at once? Yes — switch the output target to compare or copy a few side by side.
Is my body uploaded? No. All generation runs locally in your browser.
How does this differ from cURL Converter? The cURL Converter starts from a cURL command. This tool starts from form inputs — pick whichever matches your starting point.
Does it support auth? Yes — Bearer, Basic, custom headers, and API keys are handled per output target.

Runs locally in your browser. No uploads. Share links use an encrypted URL fragment.
