-- Lists the endpoints and endpoint attributes for devices in a supported
-- push notification service, such as GCM and APNS. The results for
-- 'ListEndpointsByPlatformApplication' are paginated and return a limited
-- list of endpoints, up to 100. If additional records are available after
-- the first page results, then a NextToken string will be returned. To
-- receive the next page, you call 'ListEndpointsByPlatformApplication'
-- again using the NextToken string received from the previous call. When
-- there are no more records to return, NextToken will be null. For more
-- information, see
-- <http://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html Using Amazon SNS Mobile Push Notifications>.

-- /See:/ <http://docs.aws.amazon.com/sns/latest/api/API_ListEndpointsByPlatformApplication.html AWS API Reference> for ListEndpointsByPlatformApplication.

-- This operation returns paginated results.
