Hi
You can apply a coupon to an existing subscription:
https://stripe.com/docs/api/subscriptions/update#update_subscription-coupon
With Stripe Checkout no. However with Customer Portal they can apply a promotion code when upgrading/downgrading a Subscriprion:
https://stripe.com/docs/billing/subscriptions/coupons#promotion-codes:~:text=If you’ve implemented the customer portal and turned on promotion codes%2C customers can apply a discount when upgrading or downgrading their existing subscriptions in the portal.
But If they don't upgrade / downgrae its not possible right ?
