Advanced orders Address Verification System (AVS) code processing with the WCPayments plug-in

After an approve or an approveAndDeposit financial transaction, the WCPayments plug-in issues a query command (QUERYPAYMENTS) to obtain the AVS common code for the newly created payment and sends the code to the Payment Plug-in Controller. If an AVS code exists (it is neither null nor zero), the plug-in sets a flag to inform the Payment Plug-in Controller that a warning exists for the approval transaction. The Payment Plug-in Controller then transfers the AVS code and the warning flag to the event-driven payments subcomponent.
