We are not using Shopify POS. And we don’t yet have our entire inventory on our website. Is there a way we can “redeem” a portion of the gift card in Shopify, while processing the inventory through the system in our physical store?
There’s no straightforward way to redeem a gc without using Shopify POS, AFAIK.
You could disable the card, and issue a new one for the amount of the remaining balance.
