Nowadays, the use of REST Web APIs is increasing on a daily basis, and with that said, it comes as no surprise that they are a major key component of the software development knowledge tools that you must acquire.

In this course, we will start by covering the basics: What exactly is a REST API? And what are the best practices when designing one?

This question will lead us into the world of Open API Specification, that allows us with the SwaggerHub free online tool (that we will learn how to use in this tutorial), to write a better documentation for our Web APIs.

We will go through the syntax of YAML which is the markup language we will use for this and furthermore discuss all the key elements that need to be documented, in order for our API to be completely documented.

The reasons why a well documented API is a great one vary from the fact that is much more well structured, to the fact that programmers will have a much easier time to make actual calls in order to retrieve data from it.

So, by the end of this course you will have a clear understanding of the following things:

• What is a general API and a Rest API

• What is Swagger, SwaggerHub and YAML

• What exactly is an Open API Specification

• How you can write YAML code in order to document your own API

If that sounds good to you, I look forward to seeing you in the lectures of this course! :)
