An Introduction to Web APIs

In this course we are going to explain RESTful API. We will be starting from the very beginning so We don’t expect you to know prior knowledge about API. If you have a bit of information about the web and very basic experience of coding should be enough.

After this course, you will be able to understand

  • What are APIs? What do they provide?
  • What does REST mean?
  • What is HTTP and why we need it?
  • How to use API for CRUD (Create, Read, Update and Delete) operations

At the end of the course, we will be ending up below picture and understanding each component.
