HTTP Request Code Generator

🌐 What is HTTP Request Code Generator?

Building HTTP requests for different programming languages can be tedious and error-prone. This tool lets you visually construct your API request - complete with headers, authentication, query parameters, and body content - then instantly generates production-ready code for your language of choice.

Whether you're testing a new API, documenting your endpoints, or just need a quick code snippet, this generator handles the boilerplate so you can focus on what matters.

⚙️ How It Works

Simply fill in your request details using the form above, and watch as the code generates in real-time. Select from 9 different language/library combinations to get exactly the code you need.

🔥 Key Features:

  • All HTTP Methods: GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS
  • Dynamic Headers: Add as many custom headers as you need with enable/disable toggles
  • Query Parameters: Build complex URLs with multiple query string parameters
  • Multiple Body Types: JSON, Form Data, Raw text, and Binary support
  • Authentication: Bearer Token, Basic Auth, and API Key (header or query)
  • 9 Output Formats: cURL, JavaScript (fetch/axios), Python (requests/urllib), Java (HttpClient/OkHttp), Go, and Rust
  • One-Click Copy: Copy generated code instantly to your clipboard
  • Settings Persistence: Your preferences are saved to Local Storage

📋 Supported Languages & Libraries

cURL (Bash)

Best for: Command-line testing, shell scripts, CI/CD pipelines

The universal HTTP client. Works on any Unix-like system and is perfect for quick API testing or automation scripts.

JavaScript - fetch

Best for: Browser applications, modern Node.js (18+), Deno

The native browser API for HTTP requests. No dependencies needed - it just works everywhere.

JavaScript - axios

Best for: Node.js backends, React/Vue apps, when you need interceptors

A battle-tested HTTP client with great error handling, automatic JSON parsing, and powerful features like request/response interceptors.

Python - requests

Best for: Scripts, data pipelines, backend services, API integrations

The de facto standard for HTTP in Python. Clean API, handles encoding automatically, and everyone already knows it.

Python - urllib

Best for: When you can't install external packages, standard library enthusiasts

Comes bundled with Python - no pip install required. More verbose but dependency-free.

Java - HttpClient

Best for: Java 11+ applications, when you want to avoid external dependencies

Built into modern Java. Async-capable with a fluent builder API.

Java - OkHttp

Best for: Android apps, high-performance Java backends

The go-to HTTP client for Android development. Efficient, reliable, and handles connection pooling automatically.

Go - net/http

Best for: Microservices, CLI tools, high-concurrency applications

Go's standard library HTTP client. Lightweight, fast, and sufficient for most use cases.

Rust - reqwest

Best for: Systems programming, when performance and safety matter

The most popular HTTP client in the Rust ecosystem. Async by default, with great ergonomics.

💼 Common Use Cases

1. 📚 API Documentation

Generate code samples for your API docs. Instead of manually writing examples for each language, build the request once and export code for all supported languages.

2. 🧪 Quick API Testing

Need to test an endpoint but don't want to open Postman? Build your request here, copy the cURL command, and run it straight from your terminal.

3. 🔧 Integration Development

When integrating with a third-party API, generate starter code in your language. The generated code handles headers, auth, and body formatting correctly - just plug in your values.

4. 📖 Learning & Teaching

See how the same HTTP request looks across different languages. Great for understanding HTTP fundamentals or learning a new language's HTTP client.

❓ FAQ

Q: Does this tool actually send HTTP requests?

A: No - this is purely a code generator. It creates the code for you to run in your own environment. No requests are made from this page.

Q: Is my data safe?

A: Absolutely. Everything happens locally in your browser. URLs, headers, tokens - none of it ever leaves your machine or gets sent to any server.

Q: Why would I use this instead of Postman?

A: When you just need quick code snippets, this is faster and lighter. No account needed, works in any browser, and generates code for 9 different languages instantly.

Q: Can I add multiple values for the same header?

A: Yes! Just add multiple header rows with the same key name. The generated code will include all of them.

Q: The generated code doesn't work. What's wrong?

A: Double-check your URL, headers, and body format. The generator assumes valid input. Also make sure you have the required libraries installed (axios, requests, etc.).

🎯 Tips for Better Results

  • Use the enable/disable toggles to quickly test with different header combinations without deleting them
  • For JSON bodies, make sure your JSON is valid - the generator doesn't validate it
  • API keys in query params are automatically URL-encoded, so special characters are handled correctly
  • When using Basic Auth, the credentials are Base64-encoded automatically in the generated code
  • The generated code is a starting point - you may want to add error handling or customize it for your specific use case
