Answer 1

There is no dimension for user identification available through API. If you have GA360 and enabled the BigQuery integration, you can extract clientId / userId level information by querying the tables in BigQuery. According to this guide

When you initially link an Analytics reporting view to BigQuery, Analytics exports 13 months or 10 billion hits (whichever is smaller) of historical data to BigQuery.

Another solution is to create a Custom Dimension of user scope and pass clientId with it in Google Analytics. Then using API, you will able to fetch the required information.
