# API Testing – REST API Client & HTTP Request Tester

API Testing is a powerful, modern, and lightweight REST API client designed for developers, QA engineers, backend engineers, DevOps professionals, software testers, and students who need to create, test, debug, and manage HTTP API requests directly from their Android devices.

Whether you're debugging a production issue, validating backend services, testing REST endpoints, or exploring public APIs, API Testing provides a fast, reliable, and professional mobile experience that helps you stay productive wherever you are.

Built with performance, flexibility, and usability in mind, the app enables you to send requests, inspect responses, organise projects, manage multiple environments, and streamline your API testing workflow.

## Comprehensive HTTP Request Builder

Create and send HTTP requests using:

• GET

• POST

• PUT

• DELETE

• PATCH

Configure custom headers, query parameters, authentication, request bodies, and advanced networking options to match your API requirements.

## Environment Management

Manage global and environment-specific variables with ease.

Quickly switch between development, testing, staging, production, and local environments without manually changing URLs, API keys, or other reusable values.

## Collections and Organisation

Save requests into custom collections and folders to keep your projects organised.

Maintain structured API workflows, edit saved requests, and quickly access frequently used endpoints.

## Advanced Response Viewer

Inspect responses using a fast viewer with syntax highlighting for JSON, XML, and HTML.

Search large responses, review HTTP status codes, inspect response headers, monitor response times, and analyse response data efficiently.

## Authentication Support

Access secure APIs using built-in authentication methods.

Supported authentication includes:

• Bearer Token

• Basic Authentication

• API Key Authentication

Quickly configure authentication for different APIs and environments.

## Flexible Request Bodies

Supports multiple request body formats, including:

• JSON

• Plain Text

• XML

• HTML

• Multipart Form Data

• x-www-form-urlencoded

• GraphQL

• Binary Data

Upload files, submit forms, send structured payloads, or test GraphQL endpoints from one application.

## Developer Utilities

Boost productivity with built-in developer tools.

Generate cURL commands, inspect complete request and response headers, monitor response times, and analyse network communication for faster debugging.

## Request History

Automatically save recently executed requests for quick access.

Re-run previous requests, continue testing without rebuilding configurations, and speed up your development workflow.

## Production-Ready Controls

Configure request timeouts, SSL verification, redirect handling, and other networking options to suit different development and production environments.

## Built for Modern API Development

API Testing is ideal for REST API testing, backend development, web service validation, mobile application development, server integration, API debugging, GraphQL development, cloud service testing, and software quality assurance.

Whether you're building applications, integrating third-party services, validating backend infrastructure, or learning API development, API Testing provides the essential tools needed to work efficiently with modern HTTP services.

Designed for speed, reliability, and productivity, API Testing brings professional API testing capabilities to your Android device, helping you build, test, and debug APIs anytime and anywhere.
