About

API Tester by Automate.Cloud is a Chrome extension that provides a comprehensive API testing tool with a side panel interface. It allows users to:

Test APIs directly from the browser with support for various HTTP methods

Organize requests into collections with authentication settings

Validate responses using multiple validation types (status codes, response time, contains text, etc.)

Manage authentication with support for API keys, Bearer tokens, and Basic auth

Run test suites and view detailed results in an intuitive interface

The extension operates through a side panel that can be opened from any webpage, making it convenient for developers to test APIs while browsing documentation or working on web applications. It includes features similar to Postman but integrated directly into the Chrome browser for quick access and testing.
