Retrieve and manage bookings for a property using the Newbook REST API v2.

Steps

1. Get REST API access enabled for the Newbook account and obtain API credentials from Newbook.
2. Call the bookings list endpoint to retrieve bookings within a given date/time period rather than pulling the entire booking history at once.
3. Read the inventory_item array on each booking, including its stay_cost_contribution field (whether an item is included in, increases, or is excluded from the nightly rate).
4. Paginate list calls with offset/limit parameters and loop until data_count reaches data_total, since results default to a limited page size.
5. Use the corresponding create/update booking calls to modify a reservation rather than editing inventory_item records outside the booking object.
