Shopify Gift Cards
If you create a gift card product in Shopify and do not assign it an Stock-keeping Unit (SKU), Shopify automatically uses the SKU WebOrderGiftCard. You can then create a product in NetSuite with the SKU WebOrderGiftCard. NetSuite Connector automatically matches both SKUs and no further steps are needed.
If you are using a different SKU for Shopify gift card items, make sure you have a matching item in NetSuite set with that SKU value. Typically this is a non-fulfillable item. Do not use a gift certificate item in NetSuite as the item will not sync properly.
