FAQ

What is an HTTP request builder?
An HTTP request builder lets you visually construct HTTP requests by specifying the method, URL, headers, query parameters, authentication, and body. It then generates ready-to-use code snippets in multiple programming languages.
Which programming languages are supported?
The tool generates code snippets for cURL (command line), Python (requests library), JavaScript (fetch API), Go (net/http package), Java (HttpURLConnection), and PHP (cURL extension).
Is my data sent anywhere?
No. All processing happens entirely in your browser. Nothing is sent to any server. Your URLs, tokens, headers, and body content never leave your device.
How does the JSON pretty-print work?
Click the "Pretty Print JSON" button to auto-format the request body. The tool detects JSON content and re-indents it with 2-space indentation for readability.
What authentication methods are supported?
The builder supports Basic Auth (username and password encoded as a header), Bearer Token (Authorization: Bearer header), and custom API Key (configurable header name and value).
