How to share your feed?
The "Preview" section generates the preview of the first 10 products in your export (3). If you've modified the data using the rules, it will be shown here (4).
To generate the feed, click Adjust changes (2), simply copy (5) the link to the product feed and share it with a selected publisher.
The link to the product feed is also available on the list of exports in the Exports tab and directly on the "Dashboard".
