Description

Want to build confidence in API testing and truly understand how APIs work in the real world?This course offers a complete, hands-on introduction to API testing using Postman, one of the most powerful and widely used tools for testing APIs. Designed for beginners, this course helps you develop both the practical skills and the conceptual understanding needed to work with APIs confidently and effectively.Whether you're just starting your journey in tech or looking to strengthen your testing skills, you’ll gain the ability to inspect and test APIs using structured, real-world examples. No coding or prior experience is required.Through clear lessons and guided practice, you'll learn how to send different types of HTTP requests, examine response data, and use Postman's interface to simulate real-world API scenarios. You'll also explore important API concepts and terminology to help you speak the language of APIs with ease.What You’ll Learn:Fundamentals of APIs and HTTP (methods, headers, parameters, status codes)Sending and validating GET, POST, PUT, and DELETE requestsUnderstanding RESTful APIs and other API stylesUsing Postman’s Collections, Environments, Variables, and WorkspacesManaging request headers, bodies, authentication, and query stringsReading and interpreting API responses and status codesWorking with public APIs for real-world practiceCommon API testing terms, tools, and best practicesBy the end of this course, you'll be able to confidently test APIs, troubleshoot issues, and use Postman to explore how modern applications communicate. Each section is designed to build on the last, ensuring you not only use Postman effectively, but understand the "why" behind each action.This course is ideal for QA testers, developers, students, or anyone interested in learning how to test and work with APIs — all without writing a single line of code.
