For domestic debit cards on

 you must include payer authentication data in the
ccAuthService_cavv
 and
ccAuthService_commerceIndicator

The response message from the payer authentication enrollment service indicates whether a payment card requires single-message processing or dual-message processing. In the response message, the value for the ACS URL response field includes a
binType
 parameter.
A
binType
 value of
S
 indicates that the payment card is a single message service (SMS) card. For an SMS card, you must request the authorization and capture services together, and the request is automatically processed with single-message processing.
For any other
binType
 value, you can request the authorization and capture services separately or together. When you request the services together, the request is processed with dual-message processing.
