# Amazon Connect Customer agent workspace AppController API
<a name="api-reference-3P-apps-app-controller"></a>

The Amazon Connect SDK provides an `AppControllerClient` to control applications in the Amazon Connect Customer agent workspace.

The `AppControllerClient` accepts an optional argument, ` ConnectClientConfig` which itself is defined as:

```
export type ConnectClientConfig = {  
    context?: ModuleContext;  
    provider?: AmazonConnectProvider;
};
```

If you do not provide a value for this config, then the client will default to using the ** AmazonConnectProvider** set in the global provider scope. You can also manually configure this using **setGlobalProvider**.

You can instantiate the AppControllerClient as follows:

```
import { AppControllerClient } from "@amazon-connect/app-controller";

const appControllerClient = new AppControllerClient({ provider });
```

The following sections describe API calls for working with the App Controller API.
