Hi Team,
Thank you for reaching support. The 'uservertical' is prefix for complex criteria type CriterionUserInterest. They will have a string representation of the form prefix::identifier as mentioned in this reporting guide. The 'customaffinity::111111' is the valid affinity categories and corresponding criterion IDs used in CriterionUserInterest. For your other concern, it is not possible to change the language of extracted Audience Ids via API. Let us know if you need additional information.

Hi Team,
The document you are referring to is Google Ads API Beta documentation. This has been moved to beta recently. Please refer to this blog post for more information on this. The campaign_audience_view.resource_name will return the criteria Id in its resource via Google Ads API as mentioned in the shared guide. We recommend to continue running production systems using the AdWords API. While Google Ads API is in “beta”, you may use the new API for testing and development work in preparation for future migration. Please keep in mind that during this "beta" phase, there may be breaking changes in the Google Ads API. Let us know if you need additional information.
