impression

val impression: List<String>?

A list of action IDs that represents the sequence of actions you have shown the user. For example, ["actionId1", "actionId2", "actionId3"]. Amazon Personalize doesn't use impressions data from action interaction events. Instead, record multiple events for each action and use the Viewed event type.
