In the last several years API testing has become more and more in demand and Postman is one of the best tools for this purpose which should be up in the sleeves of every QA Engineer.

First of all, what is API?

API (Application Programming Interface) – is an interface for data exchange between the server and other applications or components of the software. It is a contract that defines how they interact with each other user requests and responses. In general API architecture is usually explained in terms of client and server. The application that sends the request is called the client, and the application that sends the response is called the server. Using corresponding API tools helps testers in the API testing and creating mock servers (simulators of the application). For example, with the help of Postman, you can test how to register a new user of the application without UI, and how it adds and deletes data about it on the server.

So what does the Postman do?

It can help you to create, read, update and delete (CRUD) requests, test APIs, build and manage APIs, publish and share these APIs, create collections and workspaces, automate many processes, and even more!

Why Postman?

Simply, because it is free, user-friendly, and accessible. But also you can use Postman to create all kinds of APIs (REST, SOAP, GraphQL, etc) and it supports all possible HTTP methods. The possibility to create collections makes it easier to manage, share and cooperate with your API calls, simplifying maintaining testing processes. In the latest updates were added workspaces and the possibility to create environments for a few team members. And last but not the least, its an enormous number of different tutorials, guides, and other educational documentation, so despite the huge amount of Postman’s features it is easy to get into it.


Postman is a great and versatile tool and will come in handy for both beginners and experienced users. Also, it will be a great addition not only for QAs but for the whole development team. So if you still haven’t gotten accustomed to Postman yet, it is never late to start learning!
