Official updates（UTC）
- identified**Investigating** — We’re seeing payment declines on some U.S. business Mastercards, including some Brex cards. 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.
