can pay with like plugin be used to generate a discount code after share?

Can the "Pay with a Like" plugin be used to provide the user with a discount code to lower membership subscription ? or together with the membership plugin

all users see one page i.e. Pricing table A then if user uses the "pay with a like" to share that page then they are direct to a differnt page (accessible only by completing the pay with like) to reveal a reduced membership rate? but if somone trys to access that page directly with the url they will not have permission to view it unless they have passed the pay with like
What kind of settings would need to be enabled for this (if possible)
