Asset-Level Metrics Availability in Google Ads API (Performance Max)

[Artem Kalancha (Akelen)]

  I'm reaching out to inquire about a limitation we've encountered in the Google Ads API (currently using v20) concerning Performance Max campaigns and asset-group level performance reporting.  

Could you please clarify the following:

1. Why are raw performance metrics (e.g., clicks, CTR) unavailable for individual assets in the asset_group_asset resource via the API, even though similar insights are presented in the Google Ads UI?

2. Are there any plans to make this data available in future versions of the API (e.g., v21 or beyond)?

3. Is there a recommended alternative or best practice for programmatically accessing asset-group level performance beyond performance_label in Performance Max campaigns?

Thank you in advance for your support and clarification.

Hi,

Thank you for reaching out to the Google Ads API support team.

Retrieving performance data like clicks, impressions, and CTR of individual PMax assets via the asset_group_asset is not supported in the Google Ads API. I will raise a request for this data to be supported in the API; however, this is subject to review. So, I cannot provide a scheduled timeline for its availability in the API. I recommend you follow our Release Notes and Blog Post for future updates.

I hope this clarifies.
 

Thanks,
 

Google Ads API Team
