# Standardized target and operation names across Function APIs

We’ve standardized target and operation names in the [Cart Transform](https://shopify.dev/docs/api/functions/2025-07/cart-transform), [Delivery Customization](https://shopify.dev/docs/api/functions/2025-07/delivery-customization), [Fulfillment Constraints](https://shopify.dev/docs/api/functions/2025-07/fulfillment-constraints), [Order Routing](https://shopify.dev/docs/api/functions/2025-07/order-routing-location-rule), [Payment Customization](https://shopify.dev/docs/api/functions/2025-07/payment-customization), [Cart and Checkout Validation](https://shopify.dev/docs/api/functions/2025-07/cart-and-checkout-validation) APIs for better consistency and extensibility. The Cart and Checkout Validation API now returns operations like other Function APIs. Please note that these changes will only affect functions using version 2025-07 and later.

Unchanged APIs:

* Discount, Order Discount, Product Discount, Shipping Discount and Discounts Allocator
* Local Pickup and Pickup Point Generator
