there is no such option at the moment. Can you please tell me how will Gift Card impact the booking process? Is it going to be free or there will be some discount?
My actual customers can buy gift cards for our services. It is a code with a value associated.
So, before paid, users can validate a gift card code and the reminder of the gift card in the system is going to be applied to the final price. After the successful pay the gift card should be decrease in the amount the user use.
It will be good if the payment module has the option to add gift cards. It will be better if users can use the same plugin to buy gift cards. 🙂
