## Overview

The API Request Code Snippet Generator allows developers to instantly convert HTTP request details into ready-to-use code snippets for cURL, Fetch, Axios, and other popular programming languages.

## Inputs

- **Request URL** (text): https://api.example.com/users
- **HTTP Method** (select)
- **Headers JSON** (textarea): { "Authorization": "Bearer token", "Accept": "application/json" }
- **Query JSON** (textarea): { "page": "1", "limit": "20" }
- **Body** (textarea): { "name": "Alice", "role": "admin" }
- **Body Type** (select)
- **Response Type** (select)

## When to use

- When you need to quickly generate cURL commands for testing endpoints in your terminal.
- When integrating a new API and you need boilerplate code for your frontend or backend application.
- When sharing API documentation or reproduction steps with team members in a standardized code format.

## How it works

- Enter the target API URL and select the appropriate HTTP method (GET, POST, PUT, etc.).
- Input your headers, query parameters, and request body using the provided JSON fields.
- Select the desired body type and response format to ensure the generated code matches your requirements.
- Copy the generated code snippets directly into your project files.

## Use cases

- Rapidly prototyping API calls during frontend development.
- Generating documentation for internal microservices.
- Debugging API connectivity issues by testing requests via cURL.

## Frequently asked questions

### Which programming languages are supported?

The tool generates snippets for cURL, Fetch, Axios, and other common languages and libraries used in modern web development.

### Can I include custom headers in my request?

Yes, you can input custom headers in the 'Headers JSON' field to include authentication tokens or content-type definitions.

### Is my data stored on your servers?

No, this tool processes your input locally to generate the code snippets and does not store your API credentials or request data.

### Does it support different body types?

Yes, you can specify the body type as JSON, text, or form-urlencoded to match your API's expected input format.

### Can I add query parameters to the URL?

Yes, use the 'Query JSON' field to define your parameters, and the tool will automatically append them to the generated request code.
