public class MpnSubscriptionInfo

Specifies a Push Notifications subscription, used with MPN-related requests of the MetadataProvider.

Push Notifications is an optional feature, available depending on Edition and License Type. To know what features are enabled by your license, please see the License tab of the Monitoring Dashboard (by default, available at /dashboard).
