A Verify request returns success if the cardholder information was verified by the issuer. If AVS or CVV data is included in the message, the AVS or CVV result code will appear in the response. This is useful when you want to determine a card’s validity but are not ready to authorize the card.
Note: Vendor accounts need special permissions to use this operation; contact Maast Support to enable it.
