What happens at the limit
Every new sign-up counts toward the maximum. When the limit is reached:- New customers who try to join see “Could not create card: Maximum number of issued cards reached” and cannot get the card.
- Customers who already have the card keep it and continue as normal.
Leave the limit off for an open-ended program you want as many customers as possible to join.
