Hi Shunya, Thank you for clarifying your concern. I am also a member of the Google Ads API team and let me provide support to your concern.
Please see my answer below for each question: "Does `criterion_id` refer to the ID of each item (e.g. placement/exclusion URLs) in a specific targeting list? ... If so, what is returned criterion_id by MutateSharedCriteriaResponse?" -To answer these questions, I can confirm that the criterion_id will return the ID of each item in a specific targeting list. Does it means that shared sets/targeting lists/items of targeting lists do NOT have unique `criterion_id`? -The said entities have IDs, but the uniqueness of the entities can be determined according to this document.
