Can my merchants offer American Express through NORBr?

Yes. American Express is in the NORBr connector catalog. Your platform enables it per merchant, and its transactions follow the same reporting, refund and reconciliation flows as cards.

About American Express

American Express operates its own card network and acquires transactions directly in many markets. A direct connection to American Express lets card acceptance, settlement and dispute handling for Amex cards run through the network itself rather than through a third-party acquirer.

See the American Express connector page for its payment methods, documentation and the markets it covers, and the full connector catalog.
