I have 2 auto renewable subscriptions Beginner for 10$ a month and Advanced for 20$ a month, I want to create an offer code TEN (Takes 10% off on monthly payment for the first 12 months) which can be applicable for both.
My purchase flow in the app allows users to select a product before invoking the payment sheet.
Is there a way my users can use the coupon code "TEN" and get the same benefit for what ever subscription they have selected?.
as of not I have tried adding custom codes and was unsuccessful.
Please help.
