Im implementing recommendation by using as criteria the most viewed product. Assuming that all products have been tracking via AA, how can I send the information as most viewed product to AT?
Target detects view behavior when your request to Target includes the entity.id parameter on product pages. Then you pick "mboxes" as your data source for the criteria. Here's a link to a help doc on a basic Recommendations implementation for a product page. It passes the entity.id and a couple other related attributes.
