'upc' renamed to 'gtin' in Google feeds
Jun 15, 2012
We have renamed the 'upc' attribute to 'gtin' in all the Google feeds. There is no need to take any action; we are just informing you of the change.
Whatever field you had previously mapped to 'upc' will now be mapped to 'gtin'. GTIN (Global Trade Item Number) is a superset of UPC, so this change is backward compatible. If you already had a 'gtin' attribute, or if you have a Custom feed, we manually updated your feed and carried over any previous settings.
GTIN is a superset of all the global trade identifiers, so you can specify any of the following: UPC, EAN, JAN, and ISBN. Our system validates the format of the GTIN field, and it will also validate UPC, EAN, JAN, and ISBN fields if they are defined separately.
Multiple GTIN (or UPC/EAN/JAN/ISBN) values separated by commas are considered valid. We corrected a bug in our validation rules to allow this now.
If you have questions regarding Google's transition to pay-per-click, please read our new support article:
We are planning to offer more tools to support this transition in the near future.
