Last updated May 17, 2026. Wyllo is the rebrand of NoFraud and Yofi; the platform and customer quotes referenced in this post are the same team, evolved.
Shopify sunset its Fraud Filter app on January 31, 2025. Merchants who relied on Fraud Filter for basic order screening were directed to migrate their rules into Shopify Flow, Shopify’s general-purpose workflow automation tool. The migration was never designed to deliver real fraud prevention, and over a year on, the gap between what Shopify Flow can do and what a modern fraud platform actually requires has only widened.
This guide breaks down where Shopify Flow falls short as a Fraud Filter replacement, the seven specific capabilities that separate a real fraud platform from a workflow automation tool, and how Wyllo plugs the gap left when Fraud Filter went away.
Key Challenges With Shopify Flow as a Shopify Fraud Filter replacement
- Manual effort to migrate. Not all Fraud Filter rules transferred automatically. Rules unused in the previous 12 months and rules with unsupported fields had to be recreated from scratch in Flow.
- Loss of simplicity. Where Fraud Filter offered a focused fraud-rule interface, Flow is a general workflow tool. Building equivalent logic requires assembling workflows by hand.
- Limited fraud-specific automation. Flow doesn’t support multi-layered rule conditions, advanced fraud-detection signals, or the kind of cross-journey pattern recognition that modern fraud catches require.
- No chargeback guarantee. Merchants remain financially exposed to fraud-related chargebacks. Neither Fraud Filter nor Flow ever offered reimbursement.
Flow can tag or cancel risky orders based on simple criteria. It cannot do what a fraud platform does. Below: seven reasons Wyllo is the right replacement for Shopify merchants who took fraud prevention seriously before the sunset and need to keep taking it seriously now.
1. Shopify Flow Creates Migration Work That Shouldn’t Be Your Problem
Migrating Fraud Filter rules to Flow is tedious for the supported rules and impossible for the unsupported ones. More importantly, even after migration, Flow doesn’t actively prevent fraud. It automates workflow responses to events the merchant already classified. If your fraud strategy depends on multi-condition rules, you’ll spend hours rebuilding workflows that may not produce the same outcomes as your original Fraud Filter setup.
Wyllo is a real fraud platform, not a workflow tool. Transitioning takes minutes. Once integrated, the platform protects your store automatically, screening every order against connected signals across the customer journey instead of waiting for you to define every possible fraud scenario in advance.
2. Dynamic, Customizable Rules
Where Shopify Fraud Filter and Flow rely on static rules, Wyllo lets merchants build dynamic, nested decisioning logic. Advanced Rules support:
- Nested rule creation for complex logic
- Pre- and post-screening decisions to identify fraud at multiple points in the journey
- Matching functions (contains, greater than, equals, and more) for precise definitions
These tools let you customize fraud screening to fit your business without sacrificing decisioning speed or rule clarity. Current Wyllo customers can find documentation in the Wyllo Help Center.
3. Industry-Leading Accuracy
Shopify Fraud Filter never guaranteed protection against chargebacks. Merchants stayed liable. Wyllo, by contrast, achieves greater than 99.5% fraud detection accuracy by combining AI screening with human fraud expert review.
That precision does more than catch fraud. It improves approval rates on legitimate orders, reduces unnecessary manual review work, and minimizes the false declines that quietly cost merchants more than fraud itself.
We didn’t realize how much money we were leaving on the table until we used Wyllo.

4. Fraud Detection Beyond What Filter or Flow Cover
Fraud Filter’s rule-based structure could only catch the scenarios you manually programmed in. Fraud doesn’t wait for your rules to catch up. Wyllo layers on the categories that static rules will always miss:
- Friendly fraud detection. Catches chargebacks on legitimately delivered items.
- Promo abuse prevention. Blocks shoppers exploiting discount codes through multiple account creation or coordinated stacking.
- Reseller abuse prevention. Identifies and blocks unauthorized resellers from buying inventory in bulk for markup.
- Refund and return fraud detection. Flags falsified claims, wardrobing, and the return of counterfeit or used items.
- Subscription fraud detection. Catches recurring-payment abuse and auto-cancels fraudulent subscriptions.
- Device fingerprinting that detects suspicious behavioral patterns across what look like unrelated accounts.
- Third-party data analysis that validates transaction details (addresses, phone numbers, behavioral context) against external signals.
These capabilities continuously adapt to evolving threats. Static rules never could.
5. Faster, Smoother Order Approvals
Manual review processes waste time and introduce error. Shopify Flow doesn’t truly automate fraud prevention — its rigid workflows still require human intervention for flagged transactions.
Wyllo eliminates the manual review bottleneck. Machine learning paired with human fraud expert review confidently approves legitimate orders and spots fraudulent ones in real time. The result: faster order processing, fewer customer-service tickets, and a CX team that gets time back for the work that actually grows the business.
6. Effortless Integration and Future-Proof Growth
The Wyllo Shopify integration installs in minutes. No workarounds, no complicated configurations. As your store scales, Wyllo scales with it. Advanced fraud prevention capabilities are designed to handle the volume increases, channel additions, and pattern shifts that come with growth.
7. Chargeback Protection Guarantee
Where Shopify Fraud Filter and Flow leave merchants exposed, Wyllo Payment Fraud Protection offers an optional Chargeback Protection Guarantee. If a Wyllo-approved transaction results in a chargeback, the platform reimburses the chargeback amount and related fees.
The guarantee converts the unpredictable cost of residual chargeback exposure into a fixed line item. For Shopify merchants who were already nervous about losing Fraud Filter, this is usually the line that closes the decision.

Frequently Asked Questions
Did Shopify Fraud Filter really get sunset?
Yes. Shopify sunset the Fraud Filter app on January 31, 2025. Merchants who used Fraud Filter were directed to migrate their rules into Shopify Flow, Shopify’s general workflow automation tool. Flow handles some basic fraud-related actions but isn’t a dedicated fraud prevention platform.
Why isn’t Shopify Flow a real replacement for Fraud Filter?
Shopify Flow is a workflow automation tool. It can tag orders, cancel orders, and trigger notifications based on conditions, but it doesn’t actively prevent fraud or screen against connected signals. Rule migration from Fraud Filter is manual for many rules; Flow doesn’t support multi-layered conditions or external fraud signals; and there’s no chargeback guarantee. For merchants who took fraud seriously with Fraud Filter, Flow is a downgrade.
What does Wyllo do that Shopify’s built-in tools can’t?
Wyllo provides connected risk intelligence across the full customer journey: payment fraud screening with AI plus human expert review, reseller and bot detection, friendly-fraud and returns-abuse detection, claim and policy abuse prevention, embedded decisioning inside customer-support tools, and chargeback management. Shopify’s built-in tools and Flow cover only the transaction screen. See the comparison table above for the specific capabilities side by side.
How long does it take to switch from Fraud Filter or Flow to Wyllo as a Shopify Fraud Filter replacement?
The Wyllo Shopify integration installs in minutes. Configuration and tuning to your specific patterns typically happens during the first onboarding conversation with the Wyllo team. Most merchants see results within the first billing cycle.
What’s the Chargeback Protection Guarantee?
Wyllo Payment Fraud Protection includes an optional Chargeback Protection Guarantee. If a Wyllo-approved transaction results in a chargeback, Wyllo reimburses the chargeback amount and related fees. The guarantee converts residual fraud exposure into a predictable, fixed line item.
Is Wyllo only for Shopify merchants?
No. Wyllo also has a native BigCommerce integration on the App Marketplace and works with merchants on Adobe Commerce, Salesforce Commerce Cloud, WooCommerce, and other platforms. The Shopify integration is heavily used given Shopify’s market share, though Wyllo is platform-agnostic.
Shopify Merchants Win With Wyllo as a Shopify Fraud Filter replacement
While Shopify’s built-in fraud detection covers the basics, the patterns that hurt most live well past those capabilities. Wyllo, the CX-first risk intelligence platform, fills the gap with AI-driven decisioning, human expert review, connected journey signals, embedded workflow delivery, and a chargeback guarantee that converts uncertainty into predictability.
