FAQ
The details.
What can I block?+
You can create checkout blocking rules by email, phone number, customer name, address, specific customer account, and customer tag.
How do address rules match?+
You choose which address fields matter. A checkout is blocked only when every selected field matches the rule.
What does analytics show?+
Analytics shows blocked checkout attempts, recent interception activity, estimated protected revenue, and estimated fee savings. Financial values are estimates, not guarantees.
Are IP and country restrictions checkout rules?+
No. They are separate storefront controls delivered through a theme extension. They restrict who can access the storefront before checkout.
Does the Community Blacklist prove fraud?+
No. It is an optional community signal. You choose the email and phone checks and the number of store reports required before blocking.
What happens when a rule matches?+
The checkout is blocked and the attempt is recorded in the interception log, so you can see what was blocked and the estimated value of the protection.
