  1. Identified

    **Investigating — We’re seeing payment declines on some U.S. business Mastercards. Affected cards have numbers beginning with 544015, 546400, 543502, 543799, or 512998. Some cards beginning with 513989 are also affected.** **For API customers, this can prevent automatic recharges and one-time credit purchases. If your prepaid balance runs out, your API requests may fail.** **If you use one of these cards, we recommend adding a card from a different issuer before your next payment, even if you haven’t seen a decline. If an API credit purchase has already failed, use the new card to retry the purchase.** **We’re working with our payment partners and will share updates here.**
