# Cloud Aware API calls

> Cloud Aware API calls

Use this topic to detect if your Cloud Aware title is capable of streaming so that you can [optimize your game](/build/core-features/common/game-streaming/game-streaming-optimizing-your-game) for XBOX Game Streaming.

## Set up your game for streaming

During game initialization, ensure that you've set up the game streaming component by using `XGameStreamingInitialize` as shown in the following code.

```C++ theme={null}

// Initialize the game streaming component
XGameStreamingInitialize();

```

To detect if there are any active streaming clients that are currently connected, use `XGameStreamingIsStreaming` as shown in the following code.

```C++ theme={null}
 if (XGameStreamingIsStreaming())
 {
     // The game is currently streaming to at least one device
     // Enable any customizations that might be useful when running from the cloud
 }
```

## Manage the connection state

If there are any active streaming clients, your game has a point-in-time understanding of those clients when using `XGameStreamingIsStreaming`. To receive notification when a streaming client connects or disconnects from your game, use [XGameStreamingRegisterConnectionStateChanged](/reference/system/xgamestreaming/functions/xgamestreamingregisterconnectionstatechanged).
