# Response Status Values

> ResponseStatus values returned by PlayFab real-time messages SignalR server methods, including Success, InvalidRequest, TooManyRequests, and Unavailable.

<Note>
  The REST and SignalR APIs documented here are more complex than the client SDKs. Consider using the [Lobby C++ SDK](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/pflobby_members) or [Matchmaking C++ SDK](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/pfmatchmaking_members) instead, unless those SDKs don't meet your needs.
</Note>

Possible values for the **status** member of [SignalR server method](/services/playfab/multiplayer/real-time-messages/signalr-hub#server-methods) responses.
