AdFormat Change in AdWords API and Google Ads scripts Starting January 31, 2020

On January 31, 2020, the AdWords API and Google Ads scripts will start returning UNKNOWN for AdFormat in the Geo Performance Report. All other reports with AdFormat will not be affected. The Google Ads API is not affected as the field does not exist.

Please update your code where it uses these fields:

AdWords API	Google Ads API	Google Ads scripts
AdFormat in GEO_PERFORMANCE_REPORT	NOT AFFECTED	AdFormat in GEO_PERFORMANCE_REPORT

If you have any questions while updating your code, please reach out to us on our Google Ads API and AdWords API forum or our Google Ads scripts forum.
