Shopify Flow Integration for Pareto

Shopify Flow allows you to create automated workflows that connect Pareto Order Limit with other apps or actions inside your Shopify store.


This integration helps streamline your operations, such as tagging orders or customers, sending notifications, or triggering marketing campaigns, whenever an order limit rule is reached or violated.


I. Getting started


Before creating automations, make sure you have all required components set up.


  • An active Pareto Order Limit installation
  • Shopify Flow enabled on your store
  • Any additional apps you plan to use in the workflow (for example: email marketing, loyalty app,...)


Basis Shopify Flow structure

  • Trigger: Cart limit violated and order limit violated (from Pareto Order Limit)
  • Conditions (optional): Rules evaluated based on your configured order limits
  • Actions: What happens when the conditions are met (add tags, send notifications, or trigger other apps)


II. React to limit violations (trigger)


  1. Add Pareto Order Limit as a trigger

From your Shopify Admin, go to Apps -> Shopify Flow. Click Create workflow. In the trigger step, search for Pareto Order Limit. Select one of the available triggers:


  • Cart limit violated - Triggered when customers add items to the cart that violate configured order limit rules
  • Order limit violation bypassed - Triggered when an order is created even though order limit rules were violated.


The Shopify Flow workflow editor with the trigger step open, showing the Pareto Order Limit triggers: "Cart limit violated" and "Order limit violation bypassed."


  1. Add a condition (optional)

You can filter the workflow with conditions to ensure it only runs for specific cases. Examples:


  • Only trigger when violations count is greater than 1.
  • Run only when the Rule name contain "Limit purchase 20".


The Shopify Flow condition step showing example condition filters such as violations count greater than 1 and rule name matching a specific keyword.


  1. Add an action

Once the trigger and conditions are configured, choose what should happen next. Actions can include integrations with other apps or internal store operations.


For examples:

  • Tag the order or customer (add the tag LimitViolated)
  • Send an internal notification via Slack, email or SMS
  • Trigger a marketing automation in apps link Klaviyo or Omnisend
  • Update the customer record for segmentation or follow-up campaigns
  • Automatically archive or cancel the order when a limit violation is detected.



  1. Turn on the workflow
  • Click Turn on workflow in Shopify Flow
  • Test the workflow by intentionally triggering a cart or order limit violation in your storefront to confirm it runs as expected


III. Automate limit rules with Pareto actions


Flow can now change your limit rules automatically. The app adds two actions you can use in any workflow, plus four ready-made templates. Rules created by Flow are enforced at checkout exactly like the ones you make by hand and appear in your Limits list. Flow only manages the rules it created; it never changes or deletes your manual rules. Available on all plans.


  1. The two actions
  • Set purchase limit: creates or updates a Flow-managed limit rule from the inputs you configure (target scope, limit type, value, name). The maximum must be at least 1.
  • Remove purchase limit: deletes the Flow-managed rule it previously created for that target. If there is no matching Flow rule, it does nothing.


  1. Ready-made template


Template

What it does

Cap purchase quantity when inventory runs low

When a variant's total available stock drops to or below your threshold (default 20), it sets a per-variant quantity limit.

Remove the purchase limit when inventory is restocked

When stock recovers to or above your restock threshold, it removes the low-stock limit. Use it together with the template above.

Add a purchase limit to new products when they are created

When a new product is created that matches your condition (by default, a specific tag), it applies a product-level quantity limit.

Cap a customer's order count when an order is flagged high risk

When Shopify's fraud analysis flags an order as High risk, it sets an order-count limit on that customer to restrict their future orders.


Open a template in Flow, adjust the trigger condition and the limit values to fit your store, and turn the workflow on.
