Digital Products with Unique Product Numbers or SKUs

Hi I have a question regarding ecommerce. My client wants to build a shop where they will sell digital gift cards. Was wondering if there is a way to have multiple unique ids or SKUs for one product (per product).

Example: When buying a gift card from a partner X (digital product) the customer to receive a unique code (SKU or other type of identifier) which they can use to redeem it on the partner Xs platform at checkout.

Tried testing it out with starter plan but it doesn’t allow me to test the checkout.

Thanks in advance.
