Error: Add valid UPC/EANs to your products on Shopify

To send products to Amazon, Salestio can use different sets of data, depending on your situation:

  • Usually, a barcode to match against the Amazon product catalog.
  • ASIN, when the barcode is missing.
  • Creation data and GTIN exemption, when products without barcodes are not yet in the Amazon catalog.

When all three options are missing, publishing a product may return this error:

Add valid UPC/EANs to your products on Shopify. If products do not have them, add ASINs or activate the GTIN exemption on Amazon and configure product creation in Salestio.


If your product has a barcode, add it to the Shopify product page. To use an ASIN instead, specify it directly on the item in Salestio:

Add the ASIN from Seller Central directly to the item in Salestio

Items without a barcode and ASIN require a GTIN exemption and a detailed set of specifics for publishing on Amazon:

Selling List mode


To set up product creation for a Selling List, follow the steps below:

  • 1. Add a Creation Profile from Salestio > Profiles > Creation Profiles. This profile maps Shopify product groups to Amazon categories. Product specifics, like country of origin, materials, etc., should also be added here.
  • 2. Edit your Amazon Profile in Salestio > Profiles > Amazon Profiles. Enable product creation, assign the Creation Profile, and enable the Amazon GTIN Exemption option.
  • 3. Send the item to Amazon again.
Enable product creation, Creation Profile, and GTIN exemption

Selling Products mode


Product creation details for the Selling Products mode can be added directly through Listing Data. Follow the steps below to publish the products:

  • 1. Click the pen icon on the item to edit the Listing Data.
  • 2. Enable product creation and Amazon GTIN Exemption option.
  • 3. Add the Amazon-related details (category, product type, item specifics.)
  • 4. Save the updated Listing Data and send the item again.
Enable GTIN Exemption and add product creation details
