In order to modify a customer basket containing gift items, which two hooks are required?

The choice of using the hook for "dw.ocapi.shop.basket.shipment.beforePATCH" is appropriate because it is triggered before any changes are applied to the basket shipment. This is essential when modifying gift items within a customer's basket, as it allows for any necessary validations, adjustments, or transformations to be performed before the actual update is executed. For example, if certain conditions regarding the gift items need to be checked or manipulated before the basket is updated, this hook provides the required flexibility.

This hook is particularly valuable in scenarios where customization is necessary, such as ensuring that specific rules or promotional offers related to gift items are adhered to before the basket is finalized. By utilizing this hook, developers can intervene at a crucial point in the data lifecycle, thus ensuring that the customer's basket reflects the desired state before any changes are committed to the backend systems.

In summary, this hook acts as a gatekeeper that allows developers to implement crucial logic and oversight right before an update occurs, which is vital in managing the complexities related to gift item modifications in customer baskets.
