BlocklyShopify fraud prevention guides
In-depth guides on how Shopify fraud works — chargebacks, card testing, bots and fake orders — and the defences that stop it without hurting conversion.
The Annual E-commerce Fraud Calendar
Fraud and returns are not evenly spread across the year. Some months are quiet, others are minefields. This month-by-month calendar shows where the pressure lands and what to prepare before each spike arrives.
Building Your Shopify Fraud-Prevention Tool Stack
No single tool stops all fraud. The stores that lose the least combine layers — gateway checks, a blocking app, alerts, and manual review — so each catches what the others miss. Here is how to assemble them.

3D Secure (3DS2) on Shopify: Pros & Cons
3D Secure 2 promises to shift chargeback liability off your shoulders, but it can also add checkout friction that costs conversions. Here is when it helps and when it hurts.
CAPTCHA vs. Invisible Challenges
Traditional CAPTCHA adds friction that costs conversions, while invisible challenges verify silently in the background. Here is how to decide which belongs where on your Shopify storefront and checkout.
Writing a Fraud-Loss Post-Mortem
A chargeback slipped through or a bot cleaned out your best product. Before you move on, write a blameless post-mortem. This template gives you the exact sections to fill in so the same loss never happens twice.
Representment Evidence Templates
Winning a chargeback comes down to the evidence packet you submit. Use these reusable representment templates by reason code to build compelling responses fast.
A Fraud Escalation Matrix for Teams
When a suspicious order lands, who actually decides? A fraud escalation matrix maps risk and order value to the right decision-maker so nothing stalls and nobody overrides above their pay grade.
Do You Need a WAF for Shopify?
Shopify already runs a platform-level firewall you cannot configure, so a traditional WAF is not what most merchants actually need. Here is what the platform covers and where an app-layer filter fills the real gaps.
Incident Response During a Fraud Attack
When a card-testing or bot attack hits your Shopify store, minutes matter. This runbook walks you through detecting, containing, blocking, and reviewing a live fraud incident so you can act instead of panic.
Building a Fraud Review Queue
Held orders pile up fast and every hour of delay costs conversions. Here is how to build a fraud review queue with priority rules, SLAs, and tags so nothing slips and good customers ship fast.
