# bookingIdentifier

The unique identifier associated with the initial reservation data.

## Declaration

```swift
var bookingIdentifier: String? { get set }
```

## Discussion

Discussion Prior to booking, your Intents extension provides a set of potential reservation options in the form of INRestaurantReservationBooking objects, each of which contains a unique booking identifier. When the user selects a reservation time, this property receives the booking identifier from the corresponding INRestaurantReservationBooking object. Use that value to get the details about the reservation option chosen by the user.
