Send Slack Alerts When Shopify Inventory Runs Low

This trigger activates whenever any product variant's inventory quantity changes in your Shopify store. It automatically captures the updated inventory data including available quantity and inventory item ID. The system runs continuously in the background, so no configuration is needed from you. When inventory changes occur due to sales, restocks, or manual adjustments, this trigger fires and passes the inventory data to the next step for evaluation.

The filter evaluates whether the available inventory quantity is 3 units or fewer. You can customize this threshold by changing the number from "3" to whatever low-stock level makes sense for your business. Only inventory updates that meet this condition will proceed to the next steps. If the available quantity is above your threshold, the workflow stops here and no alert gets sent.

This step automatically looks up the full product and variant details using the inventory item ID from the trigger. It retrieves essential information like product title, variant title, and product ID that will be used to create a meaningful alert message. The system handles this lookup automatically using Shopify's API. No configuration is required, and the retrieved product data gets passed forward to build your final Slack notification.

This step retrieves your Shopify store information, specifically {{shopify_2.myshopify_domain}}, which contains your store's unique domain (like "yourstore.myshopify.com"). This domain is used to build the admin URL format "https://admin.shopify.com/store/yourstore/products/[id]" that provides immediate access to the low-stock product's admin page from the Slack alert.

This step sends a Slack message to your configured channel containing the product title, variant title, current inventory quantity, and a formatted admin link.

You need to configure the channel field during setup—select the Slack channel where inventory alerts should be sent (you must invite the MESA Slack app to your channel first by typing @MESA and clicking Invite). The message format can be customized to match your team's preferences or add additional information like supplier contact details or reorder quantities.
