Tag products for a feed review when a variant barcode changes
When a variant that already had a barcode gets a different one, add the tag feed-review to its product. A changed GTIN or EAN can break listings in Google Merchant Center and marketplaces, so the product gets checked before the next feed run.

One trigger, built-in Shopify actions only, no other app needed. Nothing in it is specific to a store, so it works as soon as it is imported.

What it needs
- The app's permission Product, Variant & Collection Data Access. See Permissions and data access.
- Nothing else: turning the workflow on switches the trigger Product Variant Barcode Changed on in the app.
Install the Workflow Trigger Extensions app and grant Product, Variant & Collection Data Access on its Permissions page. Turning this workflow on switches the trigger on in the app.
Get the workflow
- Download the
.flowfile attached at the bottom of this page. - In your Shopify admin open Flow, click Import and choose the file.
- Check the steps, then click Turn on workflow.
The file is an export from Shopify Flow itself. Do not edit it by hand; change the workflow in Flow after importing it.
How it works
- Product Variant Barcode Changed carries
barcodeChangewitholdBarcodeandnewBarcode. - The Condition continues when
barcodeChange.oldBarcodeis not empty, so a variant that gets its first barcode is skipped. - Add product tags puts
feed-reviewon the variant's product.
Make it yours
- Filter your feed app or a saved product search on the tag
feed-reviewand remove the tag once checked. - Add Send internal email with the old and the new barcode.
