-- Lists the platform application objects for the supported push
-- notification services, such as APNS and GCM (Firebase Cloud Messaging).
-- The results for @ListPlatformApplications@ are paginated and return a
-- limited list of applications, 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 @ListPlatformApplications@
-- 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
-- <https://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html Using Amazon SNS Mobile Push Notifications>.

-- This action is throttled at 15 transactions per second (TPS).

-- This operation returns paginated results.
