Configuring Notification Languages
You can configure the notification language for cardholders at the card product and/or user level. Cardholder notifications include both 3D Secure one-time passcode (OTP) notifications and digital wallet token notifications. The default language for notifications is English. You can choose to send notifications in Czech, Dutch, French, German, Greek, Italian, Polish, Portuguese, Romanian, Spanish, or Swedish.
If you set notification languages at both the card product and user levels, the notification language at the user level takes precedence.
