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).
What programming languages are supported?
Our HTTP request builder generates code for cURL, Python (requests library), JavaScript (fetch API), Go (net/http), Java (HttpURLConnection), and PHP cURL. All snippets are production-ready and include proper headers and error handling patterns.
How do I use the HTTP request builder?
Visually construct HTTP requests by specifying the method (GET, POST, PUT, DELETE), URL, headers, and body. The tool instantly generates ready-to-use code snippets in cURL, Python requests, JavaScript fetch, Go net/http, Java HttpURLConnection, and PHP cURL.
Can I generate cURL commands from HTTP requests?
Yes! Simply configure your HTTP request parameters and the HTTP request builder automatically generates the equivalent cURL command. You can copy it with one click and paste directly into your terminal or API documentation.
