Close an issued card. Final: a closed card declines everything. Within about 15 minutes of closing, the card settles: the buyer’s card is refunded whatever the issued card didn’t spend, and its cap stops counting against your app’s open-card limit. Closing is optional — a card you leave alone settles when it expires — but closing once a purchase has fully completed refunds the buyer sooner. Don’t close a card the merchant may still capture on (some charge when they ship). Idempotent.
