Mock HTTP Request Generator

Used by developers, writers, and creators worldwide.

A mock HTTP request generator produces example raw HTTP requests for testing, learning, and documentation. Beneath every API call is a plain-text HTTP request — a method and path, headers, and an optional body — and seeing the raw format is the best way to understand how the web works. This tool emits a well-formed request, including headers and a JSON body for POST and PUT. Click generate and copy it into a test or a tutorial. It is ideal for learning HTTP, testing a request parser, and documenting an API. The request follows the real wire format, so it shows the request line, common headers, and how a body is attached with a content type and length. Adapt the method, path, headers, and body to your own API. Understanding the raw request demystifies tools like curl and helps enormously when debugging why an API call behaves unexpectedly.

FAQ

what is in an HTTP request

A request line with the method and path, a set of headers (like Host, Accept, and Authorization), and an optional body. The method — GET, POST, PUT, DELETE — signals the intent, and headers carry metadata about the request.

when does a request have a body

Methods that send data, like POST and PUT, usually carry a body — often JSON — along with a Content-Type and Content-Length header. GET and DELETE requests typically have no body, just a request line and headers.

why learn the raw format

Understanding the raw request demystifies tools like curl and HTTP clients, and it helps enormously when debugging. When an API call misbehaves, knowing exactly what is on the wire — the method, headers, and body — makes the problem far easier to spot.
