Verifi alerts are routed through their Cardholder Dispute Resolution Network (CDRN). To resolve these, the merchant goes into their payment gateway to refund each alert manually. RDR is triggered before an alert is issued, and routes the refund directly to the cardholder’s account. RDR refunds are executed over Visa rails, not through the processor or acquirer. If RDR is not triggered, the dispute then routes to CDRN.
