Is there a way to get Unique Users Reached over some selected campaigns using the API?

[Natig]

I tried the below query but I could not get deduplicated unique_users.

I tried replacing the campaign with the customer, but I would still get 3 rows. (and when changing from campaign to customer, I cannot filter for campaigns)
I can not simply add them since this will not give unique users.

Has anyone figured this out before?
I could not find it here.

SELECT
        campaign.id,
        campaign.name,
        metrics.unique_users,
        metrics.average_impression_frequency_per_user,
        metrics.impressions
    FROM
        campaign
    WHERE
        segments.date BETWEEN '2025-01-23' AND '2025-03-31'
       
    AND campaign.id in ('123456', '7891011', '1213141516')
