title: Is the GA User Activity API compatible with GA4?
body: <p>Is it possible to retrieve user's data from a GA4 property using the User Activity API (<a href="https://developers.google.com/analytics/devguides/reporting/core/v4/user-reporting" rel="nofollow noreferrer">https://developers.google.com/analytics/devguides/reporting/core/v4/user-reporting</a>)?</p>
  <p>I have checked the documentation but have not found anything so far. Some endpoints of the v4 API explicitly display a warning saying it is not compatible with GA4, but this User API does not display such warning.</p>
