Card issuers can provide an authentication_required decline code when declining an attempted payment
Card issuers occasionally provide an authentication_required decline code on a payment that has already gone through 3D Secure. Typically, this means that a customer should retry the payment using 3D Secure authentication.
This usually occurs on Mastercard branded cards where the card issuer has not yet updated their systems and occurs because the indicators for the authentication_required code previously signaled a different decline code.
The payer must contact their card issuer for additional information. PayStand is unable to determine the cause of this message on behalf of the payer.
The payer can provide a new payment method.
