# Removes coupon and promotion code parameters with stackable discounts ## What’s new We’re removing the singular `coupon` and `promotion_code` parameters in favor of the [`discounts`](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-03-31.basil#create_subscription-discounts) parameter that supports applying multiple discounts. ## Why is this a breaking change? The `coupon` and `promotion_code` parameters and fields are no longer available on [Subscription](https://docs.stripe.com/api/subscriptions.md?api-version=2025-03-31.basil), [Subscription Schedule](https://docs.stripe.com/api/subscription_schedules.md?api-version=2025-03-31.basil), [Customer](https://docs.stripe.com/api/customers.md?api-version=2025-03-31.basil) or [Preview Invoice](https://docs.stripe.com/api/invoices/create_preview.md?api-version=2025-03-31.basil) endpoints and respective resources. ## Impact Use the `discounts` parameter to include one or more discounts on a [Subscription](https://docs.stripe.com/api/subscriptions.md?api-version=2025-03-31.basil), [Subscription Schedule](https://docs.stripe.com/api/subscription_schedules.md?api-version=2025-03-31.basil), or [Preview Invoice](https://docs.stripe.com/api/invoices/create_preview.md?api-version=2025-03-31.basil), and read from `discounts` in the responses instead. ## Changes #### REST API | Parameters | Change |
