Our payment gateway just ate 40 orders and support was useless
Happened Tuesday morning around 9am. Sales team said customers could not finish checkout. Error kept saying "card declined" but our processor showed no attempt logs. Turns out their API key rotated and the staging URL was still wired into production. Took me 4 hours to find it because their status page showed all green. Support replied after 8 hours with a generic copy-paste answer. We lost about 40 orders and shipped nothing that day. Now I check the gateway configs every Monday morning before we open. Has anyone else had a silent API change break their whole checkout flow?
