Walk through what we're going to build in this course, basic principles of API development, requirements for the microservice architecture, and related topics.

Build out the basic microservice application for the API project, including integrating RSpec for behavioral driven development.

Learn how to use Behavior Driven Development (BDD) to drive the features of a microservice application using RSpec and Capybara.

In this section we will walk through how to implement the SMS sending functionality, including how to build RSpec stubs to test the behavior.

In this section we will integrate the ability to allow outside application to communicate with the microservice API.
