SDK Documentation


The SDK works on model classes rather than native Alexa JSON requests and responses. These model classes are generated using the Request, Response JSON schemas from the developer docs. The source code for the model classes can be found here.

This code sample will allow you to hear a response from Alexa when you trigger it. It is a minimal sample to get you familiarized with the Alexa Skills Kit and AWS Lambda.

Color Picker
