The CustomAudienceTargetingCriterion targets users from a custom audience segment.

¶ Properties

The criterion currently carries no fields — it is an empty object ({}). Its presence in a TargetingCriterion is the entire signal; the audience itself is configured outside the API.

This criterion is returned in read responses only and cannot be set via create or update requests — it is absent from TargetingCriterionInput.
