Duplicate products during import

Hi @sergeiweb

How to make sure that the plugin is comparing all the products currently uploaded on the website and not duplicating them if they are also in CSV?

A “New Items” import (https://d.pr/i/5s8uX9), which you should be using to import variable products, can’t detect products that were created manually or by other imports. As such, it’s best to create all products from a specific feed with 1 import and then continually update it as you update the feed: http://www.wpallimport.com/documentation/recurring/update-import/.

If that’s not possible, then you could write some custom code that uses our API to stop duplicates from being created, e.g.: https://www.wpallimport.com/documentation/developers/code-snippets/#do-not-create-products-with-duplicate-sku.
