Enable the Let customers pay with a gift card at the checkout toggle.
Gift Card Redemption at Checkout

Unfortunately, at this time, Wix does not allow Gifted's Gift Cards to be used on other Wix Widgets, such as Services and Bookings.
Gifted is doing everything it can to allow Wix to integrate our platform across its site.
