# Chat Widget events

The following are events to which you can subscribe your chat widget.

Update:
Events with lowercase names are deprecated. Please [migrate to the new event names](#migration-guide) to ensure compatibility.

| Event type | Description |
|  --- | --- |
| token | Issued when a user token is assigned. |
| open | Issued the chat widget is opened. |
| close | Issued the chat widget is closed. |
| chatEnd | Issued when a chat session has ended. |
| submitInitialForm | Issued when the initial form is submitted. |
| agentLeft | Issued when the agent has left the conversation. |
| agentJoined | Issued when the agent has joined the conversation. |


## Migration guide

If you're currently using the deprecated lowercase event names, update the code to use the new
camelCase event names as shown below:

| Old case | New case |
|  --- | --- |
| `chatend` | `chatEnd` |
| `submitinitialform` | `submitInitialForm` |
| `agentleft` | `agentLeft` |
| `agentjoined` | `agentJoined` |


## Example of usage:


```javascript
SinchSdk.Chat.addEventListener('token', () => {
  SinchSdk.Chat.send('message');
});
```

## How the `chatEnd` event works

The `chatEnd` event is triggered when a chat session has ended, either by the user or the agent. You
can use this event to perform cleanup actions, show a feedback form, or notify the user that the
conversation is over.

For example, you might want to display a message or redirect the user when the chat ends:


```javascript
SinchSdk.Chat.addEventListener('chatEnd', () => {
  // Show a message or perform cleanup
  alert('The chat session has ended.');
});
```
