Use the same merge script across controller and REST API implementations by invoking the new dw.order.mergeBasket business hook. Invoke the hook by using either the transferBasket endpoint and the merge=true parameter or the HookMgr in a controller. The dw.order.mergeBasket business hook unifies discrepancies between controller and REST API merging strategies. Replace your previous merging methods with the new business hook.
