# 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](https://docs.xbox.com/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/pflobby_members.md) or [Matchmaking C++ SDK](https://docs.xbox.com/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmatchmaking/pfmatchmaking_members.md) instead, unless those SDKs don't meet your needs.

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