I have contact sensors. When they change state does my server contact the alexa endpoint directly? If so, where does it get the necessary access token?
If not, does it contact the skill which then uses stored credentials to contact the endpoint? If so, how do I trigger the lambda function? And what info do I send besides the endpointID?
If not, does it contact a new lambda function? If so, how does that function get access to the credentials? And is it an API trigger?
