Push notification services, such as APNS and GCM, maintain a connection with each app and associated mobile device registered to use their service. When an app and mobile device register, the push notification service returns a device token. Amazon SNS uses the device token to create a mobile endpoint, to which it can send direct push notification messages. In order for Amazon SNS to communicate with the different push notification services, you submit your push notification service credentials to Amazon SNS to be used on your behalf. For more information, see Amazon SNS Mobile Push High‐Level Steps.
