Will the Deprecated Product Discount function API stop working after version 2026-04?

I checked the Deprecation of Product, Order, and Shipping Discount Function APIs post, and noticed that it says “If you use the existing APIs, before API version 2026-04 you’ll need to update to the new Discount Function API..”

Does this mean that we won’t be able to continue using the product/shipping/order functions after upgrading the api_version to 2026-04+ ?

Any insight is appreciated, thanks!

If you update your api version to 2026-04 you wont have access to the older product, order, shipping function api, you need to use Discount function api - Discount Function API
here is the migration guide - Discount Function API
