# Deprecation of Product, Order, and Shipping Discount Function APIs

As of API version 2025-04, the following Function APIs are deprecated:

* [Product Discount Function API](https://shopify.dev/docs/api/functions/latest/product-discount)
* [Order Discount Function API](https://shopify.dev/docs/api/functions/latest/order-discount)
* [Shipping Discount Function API](https://shopify.dev/docs/api/functions/latest/shipping-discount)

**These APIs will be removed from all future stable and unstable API versions.**

To replace these APIs, we've created the new [Discount Function API](https://shopify.dev/docs/api/functions/latest/discount), unifying the functionality of the previous APIs into a single extension.

If you use the existing APIs, before API version 2026-04 you'll need to update to the new Discount Function API. To learn how to do this, read the [migration guide](https://shopify.dev/docs/api/functions/latest/discount#migrate-from-deprecated-discount-function-apis).
