For the general information of people that may stumble upon this topic, the GitLab API ~~seems to only support token identification through headers at this point~~ supports downloading file with authentication. I use this with a self hosted gitlab instance using API v4.

my artifact has its source url as  
`url = "<gitlab instance>/api/v<version>/projects/<project id>/repository/files/<path to file in repo with escaped special characters>/raw?ref=master&lfs=true&private_token=<project token>"`  
so that a user has no need to be authenticated to pull the artifact.

That of course works only if there is not too much security control there. If a user-by-user authentication must be used, I don’t think it is possible at the moment.
