Hi Dan,
Thank you for reaching out to us. You can use the “Campaign Criterion” type report to see mobile_app_cateogry_constant on the campaign level. Let me know if you have further questions.
Thank you,
Bryan, Google Ads API Team
Hi Dan,
Thank you for the update. You will receive the mobile_app_category_constants that are associated with each campaign (if there are any criterion ids associated with that campaign) using the second query. I also suggest adding “campaign_criterion.campaign” which will tell you which campaign the campaign criterion belongs to. Let me know if you have further questions.
