Invalid Input Data for product feed. Valid Product Identification was not provided

Error "Invalid Input Data for product feed. Valid Product Identification was not provided"

This error indicates that the Amazon service could not find the product's barcode inside your export feed.

To sell products on Amazon, the products need to have barcodes (UPC/EAN codes) or GTIN exemption for the Brand/Category combination. 

For exporting products to Amazon, Salestio will try to match your store products to the items on the Amazon marketplace. Amazon is a catalog-based marketplace, where every item exists only once. Corresponding items have already been added to Amazon for most of the products. So, the goal of our application is to make a connection between the item from your Shopify store and the Amazon catalog.

Matching between your store products and Amazon items happens by using a barcode. Amazon supports multiple types of barcodes.

It's EAN, UPC, or ASIN code (amazon standard identifier).

If your product has a barcode, you should add it to the correspondent field on the Shopify product page. If you do not know the barcode, you can request it from the manufacture. If your products do not have EAN/UPC codes, you can ask for an exemption from Amazon to list items without it (GTIN exemption). 

For example, barcode "4051709043993" is connected to the Amazon item — https://www.amazon.de/-/en/Avery-Zweckform-Printer-Copier-Paper/dp/B0002S4H1S/

If you don't know the barcodes of your products, but you know where it is located on Amazon, you can fetch an EAN code using a third-party service.

For example. Product on Amazon DE — https://www.amazon.de/-/en/gp/product/B07HHYCY2K

ASIN code here — B07HHYCY2K

Using one of the tools available on Amazon, we will get the following results:

ASIN: B07HHYCY2K
UPC: 604007623479
EAN: 0604007623479
MPN: DFC03

Another possibility to export products without barcodes is to apply for GTIN exemption on the Amazon marketplace. It can be a little bit tricky and requires communication with Amazon support.
