Play by play is a series in which top technologists work on a solution in real time, unscripted and unrehearsed. In this course, John Papa and Shayne Boyer dive into the best practices writing great APIs, and how Swagger helps you add functionality to improve your APIs. You'll learn how to setup Swagger and customize it to enable an API to be self-documenting. By the end of this course, you'll be ready to effectively use Swagger to extend the functionality of your APIs.
