New Line Item Attributes for Shipping Plus

Corso has introduced two new line item attributes, _corso_applied_gift_card_codes and _corso_customer, to unlock more advanced Shipping Plus functionality. These attributes allow admins to track when a gift card was issued by Corso and associate it with a specific customer email, enabling shipping rules to trigger based on customer tags like VIP. Brands can now stack conditions such as customer tag and Corso-issued gift card usage to modify, replace, or add fees to shipping rates directly in checkout. This adds powerful flexibility to Shipping Plus and gives brands more control over how shipping logic is applied in high value or promotional scenarios.
