Auction Insights GAQL UNRECOGNIZED_FIELD/BAD_RESOURCE_TYPE

[Andy Willers]

- Objective: Retrieve competitor Auction Insights for Search to populate a brand dashboard.

- Environment
  - google-ads (Python) 28.4.0
  - Python 3.9
  - Using GoogleAdsService.search
  - Date windows tried: BETWEEN 2025-11-10 and 2025-11-16, and DURING LAST_7_DAYS

- What works
  - GAQL queries against core resources (campaign, customer) execute successfully.

- What fails
  - All Auction Insights resources and fields are rejected.
  - FROM auction_insight_search_campaign → BAD_RESOURCE_TYPE_IN_FROM_CLAUSE and/or UNRECOGNIZED_FIELD.
  - FROM campaign_auction_insight → BAD_RESOURCE_TYPE_IN_FROM_CLAUSE and/or UNRECOGNIZED_FIELD.
  - Fields like competitor_domain, top_domain, segments.domain, segments.domain_name, metrics.impression_share, metrics.overlap_rate, metrics.outranking_share → UNRECOGNIZED_FIELD.
  - Field discovery via GoogleAdsFieldService for those namespaces also fails (not exposed).

- Impact
  - Unable to retrieve competitor Auction Insights for Search; dashboard feature must be disabled unless a supported path is confirmed.

- Request
  - Are Auction Insight resources (campaign_auction_insight, ad_group_auction_insight, auction_insight_search_campaign) available for accounts and API setup?
  - If available, what are the correct resource and field names for competitor domain and impression share metrics in this environment?
  - If not available, please confirm so we can permanently disable this feature for the affected accounts.
  - If helpful, we can provide request IDs and the customer ID privately.
