Hi 👋 yes, you can create a Coupon with a limited duration (likely setting that to once) and then apply that Coupon to the Subscription by updating the Subscription:

https://stripe.com/docs/api/subscriptions/update#update_subscription-coupon

You can use Test Clocks to model this scenario in a sandbox where you can move time forward to see how these scenarios will play out quickly:

If you're using Subscription Schedules to control the duration of your Subscription (since you mentioned it was 12 months) you may need to instead use the Subscription Schedule to apply the Coupon for you.
