Amazon Device Messaging makes it easy for you to drive engagement with your customers and to create new opportunities for monetization and use. With Amazon Device Messaging, you can send messages to individual users on specific devices. You can update customers on game play, invite them to purchase a related product, or send other messages that create a richer app experience.
● Simple. Amazon Device Messaging is a transport mechanism, optimized to queue your messages and deliver them to a targeted instance of your app. For example, upon receiving a message, your app might post a notification, display a custom user interface, or sync data.
● Efficient. Amazon Device Messaging respects users' battery life, so you can, too. Using the Amazon Device Messaging service allows your app to avoid performing polling, a serious battery drain, while not requiring additional power to stay connected —a benefit your users will appreciate.
● Free. In addition to providing a best-in-class payload size of up to 6KB per message, Amazon Device Messaging is available at no cost to developers.
Currently the API is available to developers accepted into their beta program. You can apply at the link below...
