API Testing Tutorial Part 9 – Difference Between REST and RESTFul API

Hello Folks,

As part of our API Testing series, we will see “Difference between REST and RESTFul API” in this post.

This is frequently asked interview question in interviews and I see people are confused with terms. We will learn about them in a very easy way.

You must go through with basics of REST here.

REST stands for REpresentational State Transfer. It is an architectural style that defines a set of constraints to be used for creating web services or API. REST defines six principles and if an API is developed by following principles/contracts of REST is called a RESTFul API or REST api.

REST API and RESTFul API are not two different terms. It is same. You may find documents saying if an API follows all six constraints of REST, is called as RESTFul API. But core concept says that any API build using REST principles, is called a REST API.

More about API Testing in upcoming posts. Stay tuned.

I started from basics and went throw so many selenium tutorials. Thanks to Mukesh Otwani as his tutorials are easy and cover basics to advance. I have habit of exploring concepts by deep diving. I used to make notes. I thought of sharing my knowledge through posts and now I am here. #KeepLearning #ShareLearning
