Each rule cancels the order with refund and restock, tags it for review, or only logs it. Start with tag-only and turn on auto-cancel when you trust your rules.

Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
