## Discussion

This `subtype` field is part of the [`responseBodyV2DecodedPayload`](/documentation/AppStoreServerNotifications/responseBodyV2DecodedPayload), and further describes an event of type [`notificationType`](/documentation/AppStoreServerNotifications/notificationType). It’s present only for specific version 2 notifications.
