Hi @oussama.bergaoui
Did you find the solution for applying the coupons?
I have the same issue, as can’t implement coupons to the subscriptions.
I’m thinking about to create the coupons myself and made ‘fork’ popup ‘do you have a coupon?’. Then, those who don’t have a coupon, point to the ‘full price’ subscription workflow, and those who have a coupon, point to the ‘discounted price’ subscription workflow. I just need to create two different Products/Subscriptions in my Stripe account.
Is that seems something useful for you?
