Integrating with Shopify Flows

How the Blockify: Fraud Filter x Shopify Flow integration works

With this integration, you can:

Automate fraud detection and response using Shopify Flow.
Set up workflows triggered by Blockify events, such as Order Blocked or Order Flagged for Review.
Combine Blockify conditions (like riskScore) with Shopify Flow logic for advanced automation.
Notify your team when risky orders are detected or blocked.
Improve order safety and streamline your fraud management process.

Set up Blockify: Fraud Filter x Shopify Flow

Step 1: Enable Shopify Flow in Blockify: Fraud Filter

From app Blockify: Fraud Filter, click tab "Integration" -> click button "Set up" in section "Shopify Flow"

To proceed, please install Shopify Flow by clicking the “Install” button

Choose "Enable" to Use Shopify Flow to create workflows based on Blockify's events.

Step 2: Set up your flow

From your Shopify admin, go to app "Shopify Flow" and click "Create workflow".

Choose your trigger, condition and actions.

Click button "Turn on workflow to activate".

Available triggers and actions

In Shopify Flow, triggers start a workflow based on an event, and actions define what happens when the conditions are met. The integration of Blockify: Fraud Filter with Shopify Flow provides powerful triggers and conditions, helping you better manage and control the risk score of orders.

Triggers

Risk Analysis Completed

This trigger activates when Blockify completes risk analysis for an order.This trigger can be combined with Shopify Flow conditions, and it can also be paired with a Blockify-specific condition called riskScore.

This trigger is useful for:

Automating workflows based on order risk levels.
Taking immediate action on high-risk orders.
Combining with other Shopify Flow conditions to create customized automation.
Integrating with Blockify-specific conditions, such as riskScore, for more precise controlOrder Blocked

Order Blocked

This trigger activates when an order is blocked by Blockify due to high risk or rule violation.
This trigger is useful for:

Automatically handling orders flagged as high risk.
Blocking orders that violate fraud rules.
Notifying the team about suspicious or high-risk orders.
Integrating with other Shopify Flow conditions for customized workflows.

Order Flagged for Review

This trigger activates when an order is flagged for manual review by Blockify.
This trigger is useful for:

Identifying orders that require manual inspection.
Notifying your team to review potentially risky orders.
Preventing fraudulent or suspicious orders from being processed automatically.
Integrating with other Shopify Flow conditions to create customized workflows.

Actions

Blockify also provides two actions you can drop into any workflow, including workflows started by Shopify's own triggers such as Order created, Order paid, Order fulfilled or Refund created. Both write straight back into Blockify.

Block this visitor

Adds the IP address behind an order to your Blockify block list, so the same visitor is stopped at your storefront before they can order again.

Allowlist this visitor

Adds the IP address behind an order to your Blockify whitelist, so your block rules never stop this visitor. Use it to undo a wrong block.

Important: both actions work by IP address, not by customer account. A visitor who changes network can come back, and a customer on a shared office or mobile-carrier network effectively covers everyone else behind that address.

Ready-made templates

Instead of building a workflow from scratch, you can install one of the 25 Blockify templates published in Shopify Flow's own template library. Twenty-two of them were added on 25 August 2026.

How to install a template

From your Shopify admin, go to Apps > Flow > Templates and filter the list by Blockify.
Open the template you want and read its Setup note.
Fill in every blank field the note mentions, then click Turn on workflow.

Important: every template deliberately ships with its decisive fields empty - an order-total threshold, an item quantity, a country, a discount code, an order tag or a webhook URL. A workflow turned on with those fields blank will match far more orders than you intend. For example, Cancel and refund orders flagged in a specific risk tier will cancel and refund every flagged order if you leave the tier tag empty, and Block a buyer after you refund a suspect order will block every customer you refund.

Before a template will run

Templates on Risk Analysis Completed, Order Flagged for Review and Order Blocked need Shopify Flow enabled in Blockify (Step 1 above).
Order Flagged for Review only fires when a risk tier's action is set to Flag order; Order Blocked only fires when a tier's action is set to Block order.
The five templates on Order created, Order paid, Order fulfilled and Refund created are Shopify's own triggers. They run whether or not Shopify Flow is enabled in Blockify - they only need the app installed so their Blockify step can reach us.
Orders placed without a customer account (guest checkout) are skipped by every template that tags a customer or counts their orders.
Release fulfilment holds on low-risk orders only lifts holds that Shopify Flow itself placed.

Example workflows

Here are some powerful workflows you can build by connecting Blockify (your app) with Shopify Flow to automate your store's fraud prevention.

1. Automatically cancel high-risk orders and flag medium-risk orders for review
When Blockify completes a risk analysis for a new order, Shopify Flow can automatically take action. By adding a condition based on the risk score, you can create a workflow that automatically cancels "high-risk orders", adds a manual-review tag to "medium-risk orders", and tags "low-risk orders" as safe for fulfillment.

2. Tag fraudulent customers and send internal alerts
When Blockify automatically blocks and cancels a high-risk order, Shopify Flow can trigger subsequent actions. This workflow can automatically add a "fraud-risk" tag to the customer's profile to prevent future purchases and send an internal email or Slack notification to your fraud team to log the event.

3. Create detailed support tasks for orders needing manual review
Whenever an order is flagged for manual review, Shopify Flow can automatically create a support ticket in a tool like Gorgias or send a detailed email to your team. This allows your staff to have all the necessary information—like the customer's details, order value, and a direct link to the order—to make a quick and informed decision.
