COD Blacklist helps prevent Cash-on-Delivery fraud, fake orders, refused deliveries, and return abuse through live detection at checkout. Blacklist risky customers using phone numbers and emails, then hide COD or other payment methods in real time before the order is placed. Merchants can also report unloyal customers to a shared fraud database, helping the community prevent repeat COD abuse while keeping checkout smooth for trusted buyers.

• Blacklist risky buyers by email or phone to prevent future COD fraud orders.
• Block the checkout page for detected customers or hide payment methods for them.
• Payment rules to hide methods by risk, location, value, shipping, tags.
• Report risky customers to a shared fraud database to protect the community.
• Optionally use API key from fraud services /e.g nekorekten.com/ for risk checks.
