How to Limit Product Purchases Using Shopify Flow and DC Order Limits

With Shopify Flow and the DC Order Limits app, you can automatically tag customers who have purchased a specific product and prevent them from buying it again. This guide will walk you through setting up an automated workflow in Shopify Flow and configuring product limits with DC Order Limits.

Step 1: Automatically Tag Customers with Shopify Flow

Shopify Flow lets you automate tasks such as tagging customers based on their purchase behavior. Follow these steps to tag customers when they buy a particular product:

1. Create a New Workflow in Shopify Flow:

• Go to your Shopify admin panel.
• Navigate to Apps > Shopify Flow > Create Workflow.

2. Set the Workflow Trigger:

• Choose the trigger “Order Created.” This will activate the workflow every time an order is placed.

3. Add a Condition to Check the Product SKU:

• Use a condition to check whether the product purchased matches a specific SKU.
• Here’s a code snippet you can use in Shopify Flow to loop through order line items and check for the desired SKU:

{% for lineItems_item in order.lineItems %} 
{{ lineItems_item.sku }},
{% endfor %}

4. Add an Action to Tag the Customer:

• If the condition is met (the SKU matches), add an action to tag the customer (e.g., “purchased-product”).
• This tag will help you identify customers who have already bought the product.

Step 2: Set Up Purchase Limits with DC Order Limits

Now that your customers are automatically tagged, you can use the DC Order Limits app to prevent them from repurchasing the product.

1. Install the DC Order Limits App:

• In the Shopify app store, search for “DC Order Limits” and install the app.

2. Create a New Limit Rule:

• In the app, go to Order Limits > Create Rule.
• Set a rule for the specific product by choosing the tag on the product.
• Add a max quantity of 1, assuming the customer can only buy a single of each item.

3. Configure Customer Limits:

• In the limit rule, specify that the product can only be purchased once by customers who have the “purchased-product” tag.

4. Save and Apply the Rule:

• Once saved, this rule will prevent tagged customers from purchasing the product again.

Conclusion

By combining Shopify Flow and DC Order Limits, you can easily automate product purchase restrictions for your customers. This setup helps ensure that customers who have already bought a certain product won’t be able to purchase it again, giving you control over product limits without any manual intervention.
