# currentHistoryToken

An opaque token that indicates a point in history in the user’s Contacts database.

```
var currentHistoryToken: Data { get }
```

## Discussion

Save this token after a successful change history fetch result in your app. Then, set the saved token in [`startingToken`](/documentation/Contacts/CNChangeHistoryFetchRequest/startingToken) in a subsequent [`CNChangeHistoryFetchRequest`](/documentation/Contacts/CNChangeHistoryFetchRequest) to receive changes after that point in history.
