Blocking Products Based on Inventory Levels Using MinCart

In this scenario, MinCart will be used to block products from being added to the cart once they reach a specific inventory level. This setup involves creating a limit in MinCart and automating product tags through Shopify Flow based on inventory levels.

How It Works

When a product's inventory reaches the specified level, Shopify Flow will add the "Online Out of Stock" tag to the product.
MinCart will detect the tag and block the product from being added to the cart.
The custom message will guide customers on what to do next.

Step 1: Create a Limit in MinCart

Navigate to MinCart and create a new limit.
Configure the Limit Settings as follows:
Limit Type: Tag
Limit Name: Assign a clear and unique name to identify the limit's purpose. Example*: "Limited Inventory"
Activation Dates: Set to today's date to activate the limit immediately.
Active: Ensure this box is checked.
Audience Type: Everyone
Tags Exclusion: Leave this field blank.

Items to Target: Enter the product tag that will be added/removed via Shopify Flow. Example*: "Online Out of Stock"
Set Limits: Select By Quantity.
Maximum Tag Quantity: Set to 0 to block tagged products from being added to the cart.

Text for Maximum Not Respected: Customize the message displayed to customers, explaining why the product cannot be added to their cart.
Save the limit.

Step 2: Automate Product Tags in Shopify Flow

To complete this process, you’ll need to create an automation in Shopify Flow that adds or removes the tag ("Online Out of Stock") based on product inventory levels.

Trigger: Inventory level changes.
Condition: If inventory reaches the specified level (e.g., 0).
Action: Add the tag "Online Out of Stock" to the product.
Optionally, remove the tag if inventory becomes available again.
