 * When creating a new feed, for some reason I cannot find the value for “GTIN, 
   UPC, EAN, or ISBN” field which to my understanding is the default field for EAN
   code.

 * Dear [@gedaskk](https://wordpress.org/support/users/gedaskk/)
 * Thanks for reaching out.
 * To add a GTIN to your feed, please follow the documentation here:
   [https://webappick.com/docs/ctx-feed/google-merchant/add-gtin-ean-mpn-upc-isbn-to-products-and-make-feed/](https://webappick.com/docs/ctx-feed/google-merchant/add-gtin-ean-mpn-upc-isbn-to-products-and-make-feed/)
 * If you are using a different GTIN field, please share screenshots showing where
   you added the GTIN in WooCommerce, along with a screenshot of the feed configuration.
   This will help us investigate the issue further.
 * Kind regards,

 * Hi, I am trying to add not the CTX plugin’s custom fields but woocommerce field:
   [https://ibb.co/SpJvPVS](https://ibb.co/SpJvPVS)
   The issue is that it is not 
   visible in values selection, neither by its name or value: _global_unique_id

 * Hi [@gedaskk](https://wordpress.org/support/users/gedaskk/)
 * If you are using [default WooCommerce GTIN field](https://prnt.sc/1EI0hAPmWlGG),
   you need to use the attribute shown [here](https://prnt.sc/3ekelUpS3fND).
 * If you don’t find that attribute, make sure to clear the cache [here](https://prnt.sc/X4QDcYzTWDrZ).
 * Please let us know if you have managed to get the values.
 * Best regards,
