Steps
Query campaign-level metrics for Performance Max; ad_group and ad_group_ad queries return no rows for these campaigns.
Query the asset_group resource joined with metrics for group-level performance data.
Query the asset group combination report to see which top asset combinations are actually serving as ads.
For retail Performance Max, query listing_group_filter to get product-group-level Shopping performance.
Use asset performance labels (e.g. LOW/GOOD/BEST) rather than expecting per-ad metrics.
Known gotchas
ad_group and ad_group_ad reports always return zero rows for Performance Max campaigns because Google dynamically generates ads from assets - this is expected, not a broken integration.
The combination report shows only a sample of top-performing asset combinations, not exhaustive metrics for every possible asset pairing.
Store visit metrics are only available at the asset_group and campaign level, not below.
