How can I incorporate global identifiers in the Feed?

There are global identifiers for use with the Google Shopping feed. They are the EAN, UPC, JAN or ISBN fields and can be found in the tab on the record card for the item.

There are four methods through which you can link these GTINs to your products:

• Manually via the items record card.
• By batch editing products.
• Importing a complete catalogue.
• By integration.
