I am building a custom skills for one of my use case. I am trying to implement a feature based on a token number. If token number 2 got his order, I want Alexa to announce about the next token number. Let's say for example, 'Token Number 3, your order is ready'. I would like to know that, is there any way for me to let Alexa know about these events? Is there any API which I could call to make Alexa announce only for that specific device.
I came across few things like AVS Notifications, Alexa SDNS, Alexa Senior Living Notifications API in the Alexa documentation. I've tried reading through documentations and watched videos but couldn't find anything useful for my purpose.
You can't do it yet.
What you can do now is send a push notification to the mobile device (developer preview)
