Fraud Order Filter Setup
Shopify shows a risk indicator on every order but never acts on it automatically. Shieldy's Fraud Order Filter applies your auto-cancel rules the moment an order hits the queue.
Enable auto-cancel
- Open Fraud Order Filter.
- Toggle Auto-block fraud orders to ON.
- Set Fraud order score starts at: default
0.7(high risk only). - Choose action: Cancel order, Mark as Fraud, or both.
- Optional: enable inventory restock.
- Save.
Within seconds of order creation, matching orders are cancelled and inventory restocked.
Recommended thresholds
| Store profile | Threshold |
|---|---|
| Physical goods, low margin | 0.75 |
| Digital goods | 0.55 |
| High-value (AOV > $200) | 0.50 |
| New store (first 90 days) | 0.60 |
| Returning-customer base | 0.70 |
Start conservative (0.75) and lower over time.
What signals contribute to the score
- IP reputation and geolocation
- Billing vs shipping address mismatch
- Email domain reputation
- AVS / CVV result
- Device fingerprint correlation
- VPN/Proxy/Tor detection (adds 0.2-0.4)
- Previous chargebacks
- Order velocity (multiple orders from same IP/email)
Pair with pre-checkout rules
Auto-cancel is reactive. For full coverage, combine with pre-checkout blocks:
- Block VPN/Proxy at checkout
- Block specific email patterns (e.g.
*@tempmail.com) - Block phone prefixes
- Block ZIP codes you do not ship to
- Auto-block orders with subtotal below $5 (card-test pattern)
These are in the Enterprise plan.
Whitelist exceptions
To avoid false positives, whitelist:
- VIP customer IDs
- B2B customer tags
- Subscription renewal orders
- Gift orders (tag during checkout)
