Account Verification Service (AVS)

Implementation

AVS transactions are R0.00 (zero rand) transactions that are sent as:
- Authorize transactions only (with no capture) for dual messaging and
- Payment transactions for single messaging
TransactionType in HPP is set to CardVerification.
VerificationAction has a value of: NonPaymentAuthentication or PaymentAuthentication or Payment. These 3 types are described in the section Three types of Account Verification for Cards.

Requirements for API

If a merchant uses dual messaging (which is the default) then the Authorize method should be used and the data fields below should be in the AuthorizeRequest message.

Otherwise for single messaging, the Payment method should be used with the following data fields in the PaymentRequest message.

PaymentService = CardVerification
Amount = 0
Currency = ZAR
VerificationAction = NonPaymentAuthentication or PaymentAuthentication or Payment
All other data fields in the AuthorizeRequest or PaymentRequest as specified in the API reference
