# Adds support for script coupons ## What’s new You can now customize business logic on Stripe using [scripts](https://docs.stripe.com/billing/scripts.md). With scripts, you can define custom logic expressed as code that runs on our infrastructure, extending Stripe’s core functionality. Use scripts to customize business login on Stripe logic using Stripe’s [Coupon](https://docs.stripe.com/api/coupons/object.md?api-version=2025-04-30.preview) object. Currently, you can only associate a script with this specific type of object. ### Custom discounting logic To support the customization of discounting logic with scripts, we added a new `script` parameter on the [Coupon create](https://docs.stripe.com/api/coupons/create.md?api-version=2025-04-30.preview) method. With this new parameter, you can configure a `Coupon` to use the custom discounting logic. The `script` parameter has two required nested parameters: `id` and `configuration`. `id` is the script ID and [configuration](https://docs.stripe.com/billing/scripts.md) is any input parameter to the script. The following example illustrates how to set up a coupon that gives the buyer 20% off up to 100 USD: ```curl curl https://api.stripe.com/v1/coupons \ -u "<>:" \ -d duration=once \ -d "name=My coupon" \ -d "script[id]=bfsimpl_61S9T2y7zlKu9YlG116S8pZoN2SQpuwOX348dhXM0R9c" \ -d "script[configuration][max_discount_amount][amount]=10000" \ -d "script[configuration][max_discount_amount][currency]=usd" \ -d "script[configuration][discount_percent]=20" ``` ## Changes #### REST API | Parameter | Change | Resources or endpoints | | --------- | ------ | --------------------------------------------------------------------------------------------------------------------------------- | | `script` | Added | [Coupon#create](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### Ruby | Parameter | Change | Resources or methods | | --------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------------- | | `script` | Added | [Coupon::CreateParams](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### Python | Parameter | Change | Resources or methods | | --------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------- | | `script` | Added | [Coupon.CreateParams](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### PHP | Parameters | Change | Resources or methods | | ---------------- | ------ | ------------------------------------------------------------ | | `script`, `type` | Added | [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### Java | Parameter | Change | Resources or methods | | --------- | ------ | -------------------------------------------------------------------------------------------------------------------------------------- | | `script` | Added | [CouponCreateParams](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### Node.js | Parameter | Change | Resources or methods | | --------- | ------ | -------------------------------------------------------------------------------------------------------------------------------------- | | `script` | Added | [CouponCreateParams](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### Go | Parameter | Change | Resources or methods | | --------- | ------ | -------------------------------------------------------------------------------------------------------------------------------- | | `Script` | Added | [CouponParams](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | #### .NET | Parameter | Change | Resources or methods | | --------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------- | | `Script` | Added | [CouponCreateOptions](/api/coupons/create?api-version=2025-04-30.preview), [Coupon](/api/coupons/object?api-version=2025-04-30.preview) | ## Upgrade #### REST API 1.
