Hi,
On the AdWords API perspective, we have:
You may also refer to this mapping guide to see the concepts and naming conventions for reports in the Google Ads UI to the comparable AdWords API reports. Specifically, you may check the Geographic Report and User Locations Report section for the Geo Performance Report, Campaigns Location Target Report section for the Campaign Location Target Report.
Please let me know if you have further clarifications.
Regards,
