How to set user name when forwarding to backend service

[rshah2019]

so my ngnix configuration has following. How can I forward authenticated user name to my backend service ? My backend service would like to fetch this user name and use it to do something given each request.

    location /api/endpoint/ {
        proxy_pass http://www.example-service.com:5000
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

Hi,
did you try?

proxy_pass_header Authorization; 

or

proxy_set_header X-User $remote_user;
