What are APIs? And how do we test them?

APIs are an extremely important part of the applications that we use everyday. There are APIs being called every time you open an app on your phone, search for products on the web, or play a song from your Alexa.

If your team is developing a mobile app or web application, there are going to be APIs involved. You need to be able to understand what APIs are, how they work, and how to test them.


Are you ready to work with APIs?

In this course you will learn everything that you need to know to get started with REST API testing.

The course starts with API basics. Here you will learn what an API is and how they work.

I will be covering several tools along the way to help you validate and format APIs so that you can quickly and easily understand the purpose and content.

You will learn some javaScript which is essential when working with REST APIs.

The bulk of the course will be through exercises. We will use Postman to generate API requests. Then we will use Postman to test the requests that we created.

Finally, we will be using Fiddler to capture, view, and manipulate API Traffic.
