Shopify has its own built in fraud analysis that allows them to identify orders that could be fraudulent. They use indicators to help them identify if an order is high-risk.
Shopify can sometimes identify PayMongo payments as high-risk because PayMongo does not provide Shopify with the complete information regarding our payment gateway due to technical limitations. Rest assured that PayMongo has its own Fraud and Risk engine that protects our merchants from high-risk and possible fraudulent transactions.
