-- | Attributes 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 service.
