On Booking.com, there are independent rate plans and derived rate plans. A derived rate plan gets its rates and availability from an independent (standard) rate plan by default (not the restrictions).
To integrate it with Zeevou:
Set up a derived rate plan in Booking.com linked to your standard rate plan.
Map the standard rate plan from Booking.com to the corresponding rate plan in Zeevou.
This ensures that the derived rate plan in Booking.com follows the rates and availability defined in Zeevou via the standard rate plan mapping.
