For a given bookable item, it would be nice to have the option of adding “add-ons” and setting the price of those add-ons (or perhaps this would be done at the Event Pattern level?). Again, setting the price should not be dependent on whether we are integrated with PayPal or not, and the potential add-ons information should be returned in the API.
Good idea. But if there’s a price, we will need the PayPal module enabled to make them paid otherwise payment will not be processed.
Anyway if you want custom feature you can contact our support.
