Verify and get gift card balances

Verify gift cards are enrolled and fetch their balances.

This verifies a list of gift cards are enrolled for your gift card programme, if this feature is available via your gift card service. It then also fetches each card’s current balance.

Duplicated gift card numbers are not supported. This includes both stored gift cards, as well as those directly provided via the request.

This endpoint requires the gift-cards.read scope.
