In some cases, it makes sense for an event to not be associated with any particular item (e.g. "user logged in"). In this case, we recommend that integrators use a designated item ID. So long as this ID does not show up in any events used by the recommender implementation, it should not affect recommendation. Likewise, a designated user ID can be used for item-only events.
