Update Shopify Inventory From New Square Orders

This step automatically checks your Square account every hour for newly created orders. When it finds a new order, it captures all the order details including line items, quantities, and product information. The trigger requires no configuration from you - it connects to your Square account and begins monitoring immediately. All order data gets passed to the next step for processing.

This step takes the order from Step 1 and creates a separate processing path for each line item in the order. For example, if someone buys 3 different products in one order, the loop creates 3 separate processes - one for each product. Each iteration passes the specific line item details (like catalog object ID and quantity) to the subsequent steps. No configuration is needed as it automatically loops through all line items from the trigger.

For each line item from the loop, this step retrieves the full catalog object details from Square using the catalog object ID. It pulls essential product information like the SKU, product name, and variation details. The SKU is particularly important because it serves as the bridge between your Square and Shopify catalogs. This data automatically flows to the next step where the SKU gets used to find the matching Shopify product.

Using the SKU retrieved in Step 3, this step searches your Shopify catalog to find the corresponding product variant. It returns the Shopify product variant details including the inventory item ID, which is required for updating inventory levels. If no matching SKU is found in Shopify, the workflow will skip updating that particular item. The inventory item ID gets passed to the final inventory update step.

This step queries Square for the current inventory count of the specific catalog object ID from the loop. It retrieves the available quantity from your primary Square location and prepares this data for updating Shopify. The inventory count reflects the post-sale quantity, so when this number gets sent to Shopify, both systems will show the same available stock. This current quantity gets used in the final step to set Shopify's inventory level.

This step updates the Shopify inventory level using the current Square inventory count from Step 5. You need to specify which Shopify location should receive the inventory update by entering your store's location ID in the "location_id" field. To find this ID, go to Shopify Admin > Settings > Locations and copy the location ID for your primary inventory location. The step uses the inventory item ID from Step 4 and the available quantity from Step 5 to perform the update.
