This endpoint is to allow the updating of balance and some related statuses of a gift
card within the Ionia ecosystem.
To mark a card as Redeemed:
You need to put the exact remaining balance of the specified gift card to this API, at
which point it will deduct that value from the balance of the card and mark the card as
To mark a card as Active:
Send a negative amount between 0.01 and the original face value of the gift card.This
will add the passed balance back to the card and mark it as active again. (note that this
does not affect the actual value of the card of course, but it’s for tracking and this
specific “set as active” logic).
