⚠️ Watch the UPDATED version of this course: https://youtu.be/WXsD0ZgxjRw
What is an API? Learn all about APIs (Application Programming Interfaces) in this full tutorial for beginners. You will learn what APIs do, why APIs exist, and the many benefits of APIs. APIs are used all the time in programming and web development so it is important to understand how to use them.
You will also get hands-on experience with a few popular web APIs. As long as you know the absolute basics of coding and the web, you'll have no problem following along.
