About CartGate: Stop Card Testing
Enforce cart rules that hold, even through Apple Pay, Shop Pay, and express checkout.
Customers are getting around your cart rules. Fraudsters are placing small orders to test stolen cards. And every time it happens, you're the one paying for it. CartGate enforces your limits in a way that can't be bypassed. No matter how someone checks out. Apple Pay, Shop Pay, direct checkout links, it doesn't matter. If an order breaks your rules, it doesn't go through. Period.
- Block orders that break your rules.
- Limits hold at every checkout: Apple Pay, Shop Pay, direct links, and more.
- Stop card testing fraud by restricting cheap or suspicious order patterns.
- Prevent customers from buying incompatible products in the same order.
