Alexa Lambda Handler#

Alexa lambda handler

This code provides the lambda handler for requests from Alexa devices.

lambdaHandlers.alexa_handler.alexa_lambda_handler(event, context)#

Route the incoming request based on type (LaunchRequest, IntentRequest, etc.) The JSON body of the request is provided in the event parameter.

>>> # valid monster intent
