Use this checklist to confirm Shield is actually enforcing a rule — not just showing “synced” in Admin.
Before you start
- Protection mode is Shield
- Sync status is successful
- CheckoutGuard validation is enabled under Settings → Checkout → Checkout rules
Recommended test: minimum order value
- On Protection, enable Minimum order value and set a high amount (for example
100). - Save rules and wait until sync succeeds.
- On the storefront (incognito / guest), add a product so the cart is under that amount.
- Proceed through checkout.
- You should see CheckoutGuard’s buyer validation message and be unable to complete the order.
Other easy tests
- Max quantity per line set to
1, then try quantity2 - Guest low value with a guest cart under the threshold
After testing
Turn the test rule off or restore safe thresholds so real customers are not blocked.
