I have been reading all documents on official amazon forum regarding integrating Alexa using lambda. I have somewhere in those document read that it works with payload version 2. But when I tried to create a sample labmda function using node the demo code created is using payload version 1. I am not familier with python thats why I am trying to create this using node.
Any help is really appreciated.
What will be the use of onIntent(), onLaunch() in our lambda code?
For smart home skills? I don't think you would need those ones. I'd take a look at the API refrence here: https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/smart-home-skill-api-reference
The headers are in the documentation, but for discovery it must look like this
var headers = {
namespace: 'Alexa.ConnectedHome.Discovery',
name: 'DiscoverAppliancesResponse',
payloadVersion: '2'
};
You must attach this and the payload described in the documentation (which includes the device list and all the devices) and return it from your lambda handler function. I say this because some people assume context.succeed returns the data, which it does not.
Turning on lights is easier, here is the entire payload:
var headers = { //ALL HEADERS ARE REQUIRED AS IS. DO NOT CHANGE
namespace: 'Alexa.ConnectedHome.Control',
name: 'TurnOnConfirmation',
payloadVersion: '2'
};
var payload={
};
var result = {
header: headers,
payload: payload
};
And then you can return the result object.
