Introduction

A postman is a testing tool for Application Programming Interfaces (APIs). API acts as an interface between two apps, establishing a relationship between them.

Moreover, an API is a set of agreements, functions, and tools that an application can provide to its users for successfully communicating with different programs. As a result, we need an API every time we use an application, such as checking the news on the phone, Facebook, and more. Furthermore, this tool is capable of designing, documenting, verifying, creating, and changing APIs. Therefore, to make a career out of this domain, it is necessary to have Postman Online Training.
