question

I'm new to developing and I'm working on my first alexa skill and hit a roadblock. I've enabled account linking through Amazon login and I'm trying to do what mkzense is doing with ifttt where you set up triggers (I'll be doing this without user input and just adding on a few custom triggers) when after you authenticate it adds the triggers as smart home devices that a user can select as a trigger to launch a routine. Any idea what I can add to my lambda file that will add a smart home device capable of selecting as a trigger for a routine?
