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

The Amazon Connect SDK provides an `AgentClient` which serves as an interface that your app in the Amazon Connect Customer agent workspace can use to subscribe to agent events and make agent data requests.

The `AgentClient` accepts an optional constructor 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 agent client as follows:

```
import { AgentClient } from "@amazon-connect/contact";
 
const agentClient = new AgentClient({ provider });
```

**Note**  
You must first instantiate the [ AmazonConnectApp](getting-started-initialize-sdk.md) which initializes the default AmazonConnectProvider and returns ` { provider } `. This is the recommended option.

Alternatively, providing a constructor argument:

```
import { AgentClient } from "@amazon-connect/contact";
        
const agentClient = new AgentClient({
    context: sampleContext,  
    provider: sampleProvider
});
```
