Hi David,
Thank you for reaching out. Currently, it is not possible to pull the data under User locations view on the Dimensions tab in UI via Google Ads API. However, you could get this data using Geo Performance Report via Adwords API by modifying the predicates as mentioned in the shared guide. Let us know if you need any additional information.
Hello,
I understand your concern but as per the blog post, the sunset of average_position metric will begin with the starting week of September 30, 2019. The alternative metrics in lieu of average position are mentioned the blog post. Currently, these new alternative metrics (AbsoluteTopImpressionPercentage and SearchAbsoluteTopImpressionShare) will support Keyword Performance Report and all the other reports listed in this guide against each metrics. Let us know if you have any additional concerns.

Nikisha Patel, Google Ads API Team
