Introduction

In the current software development, environment RESTAPIs are the most basic way of sending data from your server to your client devices such as Mobiles, laptops, and even IoTdevices. Therefore, gaining knowledge on how to use the RESTAPIs is crucial for being a software engineer. Postman not only serves as a client to send APIrequests to your server but also provides many additional features such as testing of the APIs, creating a mock server, and also be used as a Proxy server.

This course is intended for application engineers in the development cycle ie: Front-end, back-end developers, and Quality assurance team.

What's Covered?

In this course, Iwill be covering the most important aspects of Postman and teaching from the perspective of a developer. We start off by learning the basics of RESTAPI, how the RESTAPIs are developed, designing the API using the OpenAPIspec. Being a full-stack developer,Itry to explain the issues that I face when doing the development as a front-end such as mocking of the APIs before the backend service is ready as well as problems faced by back-end engineers such as maintaining the version of the REST API. I also cover the essentials of APItesting and take up examples of various scenarios that need to be tested to ensure a smooth functioning backend.

Ihave created a dummy backend application in NodeJSwhich we will be using as our backend to test the application. Using this we will be able to simulate real-world scenarios and how to deal with them. If you don't have knowledge of NodeJSdon't worry as I have guided you on how to be set up the same.

Hope you enjoy the course and find it useful.

Thank you.
