Hey @stephen1, is this regarding GitLab.com? If so, then it won’t be possible for you to retrieve the primary email address associated with other GitLab.com accounts unless a user you’re querying for has chosen to publicly display their email address. This is primarily because each account on GitLab.com is owned by the specific user that created it.
End-users of GitLab.com are also not granted administrative privileges for the reasons outlined in our documentation.
