Magical Postman

An online self-study course on Postman and API - REST for testers and developers alike.

About the course

A website and a mobile app communicate through one layer in the background – the backend.

You will learn how to test the backend during this course, focussing on the most common type of API. Thanks to this course you will learn the basics of API testing, which will be useful later if you are planning on testing GraphQL. We use the Postman application to send requests to the server, validate answers and verify that the backed matches the structure that the frontend (client) expects.

You will learn how to understand the documentation and think of scenarios that can take place. Using API, you will be able to simulate the client and create testing data which will also help you while testing the frontend.

The training is not only for testers who want to learn how to test APIs but also for developers that develop APIs and want to verify their work.
