*Marketo permits a huge variety of activity types related to lead records. Nearly every change, action or flow step is recorded against a lead's activity log, which Fusion retrieves via the API. Such activities are always related to the lead record via the leadId. And while every activity has a unique id, leadId and activityDate, the primaryAttributeValueId and primaryAttributeValue will vary in their meaning.
