Wix Hotel-may need API to get at underlining data

Working with Wix Hotel.
I have a customer that either has individual rooms or the whole property for rent. If the whole house is rented out, I need to make all the rooms unavailable.
Also, if any of the individual rooms are booked, I need to make the “whole house” booking unavailable. I assume I need custom code to do that.
How do I access the Wix Hotel data?

You can’t. Wix Hotels is an older app and will never get an API. Wix has partnered with Hotelrunner to offer a newer environment which actually receives further development. So basically, Wix Hotels is a dead end.

Thank you for the info.
