# Metadata

With Sinch Chat, it's possible to provide your conversation metadata. Here's an example:


```javascript
SinchSdk.Chat.setConversationMetadata({
  once: {
    'userName': 'John'
  },
  eachMessage: {
    'phoneNumber': '123 123 123',
    'website': 'www.example.com'
  }
});
```

The metadata stored as `once` will be sent only once at the beginning of the conversation, while `eachMessage` metadata will be attached to each message.
