API Testing Fundamentals with Postman

Are you looking to start a career in software quality assurance or expand your technical skills? Understanding how to test APIs is essential in modern software development, and this course provides the foundation you need. This text-based course will guide you from the basics of what an API is to performing comprehensive tests using Postman. You will learn to construct requests, analyze responses, and automate checks, gaining the practical skills and confidence needed for real-world QA tasks and technical interviews. What you'll learn: - Understand core API concepts, including REST principles and HTTP methods. - Create and send API requests in Postman to interact with web services. - Validate API responses by checking status codes, headers, and body content. - Write basic automated test scripts within Postman to verify API functionality. - Manage test environments and variables for more organized and reusable tests. - Explore common authentication patterns like API keys and bearer tokens. - Structure and document your API tests for clear reporting and collaboration. The course begins with fundamental concepts before moving into hands-on exercises where you'll apply your knowledge directly in Postman. You will progress from simple requests to building structured test collections for a sample API. This course is designed for absolute beginners. No prior experience with API testing or programming is required, making it ideal for aspiring QA engineers, manual testers looking to upskill, or developers wanting to understand the testing process.
