About this course

Application Programming Interfaces (APIs) are software that send information back and forth between a program and a user.

The entire web runs on APIs! They are required for microservices, mobile apps, and client-side web apps like Angular, React, or Vue. They also improve the scalability and code reuse of desktop and web apps, yet often developers don't know how to build resilient, powerful APIs.

This course will teach you how to use authentication, how to protect your API, how to version your API, how to document your API, how to monitor your API, and much more.

Hi, I'm Tim Corey.

I learned software development the hard way, with lots of dead-ends, confusion, and knowledge gaps. I kept thinking, “It shouldn't be this hard!” Now I teach students how to think and code like professional developers. My goal is to make it easier for you to become a developer.
