You cannot directly change the expiration date of a gift card on Shopify. Once a gift card is created with a specific expiration date, it cannot be modified.
However, you can extend the expiration date by:
- Issuing a new gift card: You can create a new gift card with the desired expiration date and transfer the remaining balance from the old gift card to the new one.
- Contacting Shopify Support: If you have a specific reason to change the expiration date, you can contact Shopify Support for assistance.
Remember, it's important to follow Shopify's policies and guidelines when managing gift cards.
