# Integrate application with Amazon Connect Agent Workspace agent data
Integrate with agent data

To integrate your application with agent data from the Amazon Connect agent workspace, 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, see the [API reference](api-reference-3P-apps-agent-client.md) to customize your client’s configuration.

Once the agent client is instantiated, you can use it to subscribe to events and make requests.

## Example agent event


The code sample below subscribes a callback to the state change event topic. Whenever the agent’s state is modified, the agent workspace will invoke your provided callback, passing in the event data payload for your function to operate on. In this example, it logs the event data to the console.

```
import { AgentStateChanged } from "@amazon-connect/contact";

// A simple callback that just console logs the state change event data 
// returned by the agent workspace whenever the logged-in agent's state changes
const handler = async (data: AgentStateChanged) => {
    console.log(data);
};

// Subscribe to the state change topic using the above handler
agentClient.onStateChanged(handler);
```

## Example agent request


The following code sample submits a `getARN` request and then logs the returned data to the console.

```
const arn = await agentClient.getARN();

console.log(`Got the arn value: ${arn}`);
```

The above agent event and request are non-exhaustive. For a full list of available agent events and requests, see the [API Reference](api-reference-3P-apps-events-and-requests.md).
