Connector API: Add an AssignedSpaceCategoryID element to the Reservations extent.
Currently, you have BookedSpaceCategoryID in the Reservations extent. Clients are much more interested in, what room did the guest actually stay in.
Technically, we can use the AssignedSpaceID, and go back through the Spaces extent to find out the AssignedSpaceCategoryID, but it would be cleaner if the Reservations extent itself contained both the Booked Category and Stayed Category IDs.
All this functionality is already enabled in Connector API. Search for AssignedSpaceId; RequestedCategoryId.
