Riskloom Fraud Screening for Signifyd
Signifyd publishes no official WooCommerce integration. It ships supported plugins for Magento 2, Salesforce Commerce Cloud, and BigCommerce, which leaves WooCommerce stores to build their own. We built ours for a client taking chargebacks, then released it.
The plugin creates a Signifyd case server-side when an order is paid, verifies the signed webhook that carries the decision back, and gives staff a panel on the order screen to refresh the case, close it, or purchase Signifyd's guarantee.
