Hi, what field is it used to identify existing listings? Is it ID? I’m using the field ID when importing listings, but every time that I try to update an existing one via the csv import plugin, I get the error message “No listings found.”
Is the ID supposed to be a specific type? Text, number…?
Please clarify: Do you need a custom ID to match and update listings? (If the custom ID is something like a product SKU, then yes, you can do this using a custom attribute.) However, if you need to update the listing by this field (i.e., not add new listings, but overwrite the current ones), then unfortunately, there is no such feature yet; it is possible only by post ID.
