Fraud Prevention: Paymonix Fraud RulesUpdated a month ago
Fraud Prevention Rules in Paymonix
Paymonix users can set up fraud prevention rules directly within their dashboard. This feature is included with every Paymonix account and is available to all stores.
Store admins can create and manage rules as needed. Once rules are active, all orders are passed through Paymonix fraud validation. This validation applies advanced rule checks to detect fraudulent behavior and can be used either as a standalone solution or alongside integrated services such as Fraud Labs.
Paymonix fraud prevention rules can be found by navigating to Dashboard 2.0 > Store > Fraud Prevention Rules
