Hi Windsor team,
We use the Windsor.ai Google Ads connector to report on Shopping performance by product dimensions (product type L1–L5, product item ID, brand, etc.).
When we combine any product dimension with conversions_by_conversion_date or conversions_value_by_conversion_date, the request fails with: “Google Ads cannot return these fields in one request: product_item_id has no report in common with the others.” The same happens with product_type_l1 and product_type_l2.
According to the Google Ads API documentation, these metrics are selectable with shopping_performance_view, the resource that holds the product dimensions:
https://developers.google.com/google-ads/api/fields/v24/shopping_performance_view
The combination also works in the Google Ads UI report editor. So it looks like the by-conversion-date metrics are only mapped to your campaign-level reports and not to the product report.
Could you add the following metrics to the report you build on shopping_performance_view?
Ideally they should also work together with the conversion action name segment, since we need to split values by conversion action (one action holds gross profit, another revenue).
