The REST and SignalR APIs documented here are more complex than the client SDKs. Consider using the Lobby C++ SDK or Matchmaking C++ SDK instead, unless those SDKs don’t meet your needs.

Members

entityType   string The type of the entity whose subscription changed. Clients may only care about this field if they added multiple entities to the same session. Example: title_player_account entityId   string The ID of the entity whose subscription changed. Clients may only care about this field if they added multiple entities to the same session. Example: 6C6B908A2B5B9A4 topic   string A topic string, matching the topic string returned when subscribing to resources. This field allows the client to keep track of which messages are for which resources they subscribed to. Example: Opaque~Topic~String~6183258 status   string The status of the subscription change. unsubscribeReason   string optional A reason for unsubscription, that can be optionally provided by the service handling the unsubscribe request. Example: ResourceOwningServiceDefinedReason traceId   string A W3C TraceContext trace-id. The client should log this field so it can be included if you need to send a bug report to the PlayFab team. Example: 4bf92f3577b34da6a3ce929d0e0e4736
