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.
Real-time messages for Lobby and Matchmaking APIs
Overview of PlayFab Lobby and Matchmaking real-time messages, letting game clients subscribe over a persistent SignalR WebSocket to receive service updates.
The Lobby and Matchmaking
services offer a real-time
messages feature, which enables individual game clients to subscribe to
receive messages from these services. Game clients subscribe for
messages over a persistent SignalR WebSocket
connection. To learn more about
the scenario as a whole, see the conceptual documentation for Lobby and
Matchmaking real-time
messages.
To use this feature, game clients will first need to implement a SignalR client
that connects to the SignalR Hub for real-time messages.
Once connected, the clients can subscribe to
resources they would like to receive messages
for.
