We use Hotel Booking for the renting of our Gites. Quite often we get people aksing for information and part of it is to get an optional booking, besides that a booking is only confirmed after innitial payment. My problem is that I want to mark these bookings as optional and have them synchronized with Airbnb as “not avialable”.
Sorry, I am not sure I follow you correctly. Could you please clarify your request more detailed by providing an example? In case you need to edit a booking after it is made, you can easily do it within the 3.8.0 Hotel Booking version (video tutorial). As for synchronization, once accommodation is booked, it also becomes unavailable on OTA. Here is an article with more details.
