A map of the endpoint attributes. Attributes in this map include the following:
CustomUserData – arbitrary user data to associate with the
endpoint. Amazon SNS does not use this data. The data must be in UTF-8 format and
less than 2KB.
Enabled – flag that enables/disables delivery to the
endpoint. Amazon SNS will set this to false when a notification service indicates to
Amazon SNS that the endpoint is invalid. Users can set it back to true, typically
after updating Token.
Token – device token, also referred to as a registration id,
for an app and mobile device. This is returned from the notification service
when an app and mobile device are registered with the notification
EndpointArn used for SetEndpointAttributes action.
