Feeling hungry? You’ve come to the right place!

I will be going over the basics: The What’s, Why’s, Where’s, and When’s. You will learn the basics of REST APIs and I will show you how you can use POSTMAN to test making REST API calls. I will use Cisco’s Spark and Tropo as use case examples of working with APIs.
