Charge or change the card an order is paid with.
Manage the card an order is paid with:
- Charge a stored card the customer has already saved.
- Replace the order's card with another saved card.
Both take a card_id. Get it from List customer cards.
Charging or replacing a card can take money straight away: anything already due on the order is merged into one payment and charged.
Before the first payment, the customer can enter a new card themselves through a payment link or a custom checkout. Neither works once the order is active or complete.
