Under the Hood

How Skill Works

Create an Alexa Skill in the Alexa Skill Developer Console and define the interaction models as well as the intent schema. This sets up the framework for the behavior of the skill.
Create an AWS Lambda function that interfaces with the skill and translates the various intents into requests that connects to your service. This lambda function is written in Node.js.
