For greatest security and least exposure to the risk of fraudulent credit card usage in your online store, we recommend that you require your customers to provide the CVV (card verification value) security codes when placing an order in your online store and paying with a credit card. This helps to verify that the purchaser has physical possession of the card. While it is not a foolproof way to prevent fraud, it goes a long way to minimize your risk.

This CVV requirement is possible only if you elect to authorize the credit card when the order is placed. It is not available if you choose only to validate the credit card number, and neither authorize nor charge the credit card.

To set up this CVV requirement in your Nexternal Order Management System (OMS), navigate to Settings / Edit Compatible Software / Payment Gateways Preferences/ Authorization Preferences, and use the pulldown to select either "Validate and Authorize" or "Validate, Authorize and Charge", depending upon whether you want to merely authorize the card to diminish the risk of decline when you later capture the funds, or whether you want to actually capture the funds as the order is being placed.

Once you've specified your Authorization Preference, use the pulldown for "Card Validation Values" to select "required". (Selecting "optional" would defeat the purpose of this security precaution.)

Important Notes:

  • In compliance with PCI regulations, the CVV is never saved in the Nexternal platform, and it will be required when taking telephone orders or otherwise placing orders in the OMS, even if the customer for whom the order is being placed has a credit card on file.
  • Regardless of your CVV settings, bulk orders can always be created, and once a subscription is set up with the CVV, the resulting subsequent subscription orders will continue to be generated automatically.
  • Read the ? tooltip near the Authorizations Preferences for complete information regarding the implications of your selection.
