About this course

API testing is essential for modern development and integration, and Postman is the industry standard for interacting with and validating API endpoints. This course provides a practical, hands-on approach to using Postman for managing business-critical data workflows. By the end of this course, you will understand how to structure your tests, manage authentication tokens, and systematically verify that complex API workflows—like creating, updating, or deleting orders—function correctly and reliably. What you'll learn: * Understand the core concepts of REST APIs, HTTP methods (GET, POST, PUT, DELETE), and standard response codes. * Configure Postman environments and variables to manage dynamic data, authentication tokens, and reusable parameters effectively. * Practice constructing various request types to simulate real-world data workflows, such as creating new records or retrieving status updates. * Apply pre-request scripts and test assertions using JavaScript within Postman to automate validation and error checking. * Organize API calls into collections and utilize basic documentation features to share and maintain your test suites. The course begins with foundational API concepts and navigating the Postman interface, then moves into practical request creation, environment management, and writing basic validation scripts. This course is designed for absolute beginners in API testing, including developers, QA testers, and technical business analysts. No prior experience with Postman or API structure is required.
