Retrieve and Verify Data from APIs Using Postman

Understanding how to interact with web services is essential for modern development and testing workflows. Postman is the industry standard tool for exploring, testing, and documenting APIs. This course teaches you the foundational skills needed to use Postman effectively. You will learn to structure requests, manage different environments, execute basic testing scripts, and reliably retrieve and verify data from any REST API endpoint. What you'll learn: * Configure the Postman environment, including collections and variables, to manage complex API workflows efficiently. * Understand fundamental API concepts, including HTTP methods, status codes, and request/response structures (JSON). * Apply common authentication methods, such as API keys and Bearer tokens, to secure API calls. * Send GET requests to retrieve lists of resources and practice parsing the resulting JSON payloads. * Write basic test scripts using the built-in sandbox to automatically verify response data and status codes. * Practice importing and using pre-built collections to quickly test new API services. The course begins by establishing the core concepts of RESTful APIs and the Postman interface. We then move into practical exercises focused on structuring requests, handling authentication, and validating the data returned by various endpoints. This course is designed for absolute beginners with no prior experience in API testing or using Postman. No programming prerequisites are required.
