Understanding APIs and RESTful APIs Crash Course

In this course you will learn about APIs and RESTful APIs, and how they work.

There is no coding in this course.

By the end of this course you will completely understand how APIs work, and how computers talk to each other. You'll also be familiar with RESTful APIs.

You don't need to be a coder to understand APIs and how they work. I'll be using a real life example of a restaurant to demonstrate how requests work. 

The goal of this course is to help you understand APIs and RESTful APIs without needing to write any code. So next time someone says "API" you will know exactly what they are talking about (and you'll also know it's not really that technical or fancy, but that'll be our secret ;)
