CertNode Reflex

CertNode Reflex automatically defends Shopify Payments disputes with no setup required. This chargeback defense app detects each dispute, gathers evidence from your orders, fulfillments, and customer history, then submits structured defense narratives tailored to the specific dispute type—all within minutes. Built by a Stripe Partner, Reflex includes RFC 3161 certified timestamps that provide cryptographic proof of transaction events. The app activates automatically for every chargeback, so you don't need to configure anything. Pay $0 monthly fees—you only pay a 15% success fee when you win a dispute, billed directly through Shopify.
