Amazon Moments is a service that lets you increase the user actions that matter in your apps, games, websites and more by rewarding customers with physical or digital items when they complete these actions.
The moments platform triggers personalized notifications or rewards when app customers reach these moments.
You can integrate the Rewards API into your Android or iOS app, game, or website to interact with app users regarding rewards that they qualify to receive.
Once you integrate Rewards API, you can now start creating Moments campaign through Moments Console.
