I’m currently testing around and sadly fetching products isn’t working with third-party product types.
However synching works. The changes are reflected in the third-party variables.
Is there any change to implement the fetching of products with variables of a third-party plugin called ATUM WooCommerce Inventory Management and Stock Tracking?
Well, we update/fetch the core WC fields and for stock, the core fields are manage_stock which should be set TRUE and stock_quantity which should set the stock quantity number.
