Description

Postman is one of the most commonly used tools when working with REST APIs. It is used by developers to explore, test, and understand APIs during development, integration, and testing.In this course, you will learn how to use Postman through hands-on examples and a real demo API. There are no slides and no unnecessary theory — everything is done directly in Postman, step by step.We start with a short introduction to REST concepts and the demo application that will be used throughout the course. From there, you will learn how to send requests, work with headers and request bodies, and understand API responses. We then move on to authentication, variables, environments, and organizing requests using collections.As the course progresses, you will add tests, use pre-request scripts, and run entire collections to verify API behavior. You will also learn how to export and share collections, which is commonly done in real projects.The course follows the same structure as my other hands-on introductions. Each topic is introduced only when it becomes useful, and every concept is shown in practice. The goal is to help you understand not only how Postman works, but how it fits into everyday development and testing workflows.This course is beginner-friendly and designed to be a practical introduction to API testing with Postman.
