Questions about Rest API Endpoint and Managing Tours Attributes

1- There is a rest api endpoint for create and update booking? we need to create and mange the tour from a separate application of our customer.

2- It’s possibile to manage the availability of the days in calendar, for the same tours product, depending by value of attributes? for example:
The same day of calendar is available or not depending on value of attribute language for the same tours product. Here I send you an example of our customer. In this case, for different value of attribute language, the days into the calendar are available or not.

3- If it’s not possible can you quote us this upgrade?

4- If 3 it’s not possible, may we install this plugin on your travelWp theme
