Missing Bid Strategy Type and Cost for "Share of Voice" Campaigns

[Tobias Modig]

Hi Google Support,

I'm encountering an issue with my Google Ads API integration.

The API works well in general, but for campaigns using the "Share of Voice" (i.e., Target Impression Share) bid strategy, the response returns bidding_strategy_type = UNKNOWN, and no metrics.cost_micros.

However, in the Google Ads UI, these campaigns display the correct bid strategy type and cost values. Other bid strategy types also behave as expected via the API.

Could you please confirm if this is a known limitation or expected behavior when retrieving "Share of Voice"/"Target Impression Share" campaigns via Google Ads API?

For reference, here's the GAQL query I'm using:

SELECT
  metrics.phone_calls,
  metrics.video_quartile_p75_rate,
  campaign.id,
  metrics.interaction_event_types,
  metrics.search_rank_lost_impression_share,
  campaign.bidding_strategy_type,
  metrics.video_views,
  segments.date,

Let me know if you need any additional details.

To replicate the issue from our end, kindly provide the uncropped Google Ads UI screenshot where campaigns display the correct bid strategy type and cost values and the same you are trying to retrieve via the API.
