HTTP Request Builder
Construct an HTTP request - method, headers, query parameters, and body - and get the equivalent cURL command and code snippet.
Use the fields below to construct any HTTP request - method, headers, query parameters, and body - and get the equivalent cURL command and JavaScript fetch snippet.
Everything runs in your browser - no request is sent from here, this tool only builds the request representation for you to use elsewhere.
What Is an HTTP Request Builder?
An HTTP request builder helps you assemble every part of a raw HTTP request - method, headers, query string, and body - through a simple form, then converts it into a ready-to-use cURL command or fetch snippet.
Why Use This Tool?
Useful for protocol-level debugging, writing API documentation, teaching HTTP fundamentals, or quickly producing a request you can paste into a terminal or script without memorizing exact syntax.
How to Use the HTTP Request Builder
- Select the HTTP method.
- Enter the target URL and any query parameters.
- Add the headers your request needs.
- Enter a request body if the method supports one.
- Copy the generated cURL command or fetch snippet.

If you already have a cURL command and want it converted into a specific programming language, use the cURL to Code Converter. If you want to actually send the request and see a live response, use the REST API Tester.
