Ab Version 2.1 der Content API können Sie Subfeeds verwenden, um Produktdaten teilweise zu aktualisieren. Mit Teilaktualisierungen mit Subfeeds können Sie Anfragen senden, die nur die Felder enthalten, die Sie ändern möchten, ohne dass sich dies auf die restlichen Produktdaten auswirkt. Nachdem Sie Ihre Subfeeds im Merchant Center erstellt haben, können Sie Teilaktualisierungen vornehmen. Dazu fügen Sie beim Aufrufen von Products.insert und Products.delete den Abfrageparameter feedId hinzu.
