Notifications API

You can use the Alexa Notifications REST API to send notifications to your customers. You can specify either of the following notification types:

  • Device notification – For headless devices like Amazon Echo Dot, this is a yellow ring and a chime sound. For multimodal devices, it's a banner and a persistent notification indicator.
  • Announcement – For headless and multimodal devices, this is a voice announcement. Multimodal devices also display a message on the screen.
