How to Get User Login Id ?

The URL is listed as:
https://projects.zoho.com/portal/{PortalName}/api/private/xml/dashbs/getlogin

However when I try it. It gives General Error 6500.

I accidentally tried changing the URL to
https://projects.zoho.com/api/private/xml/dashbs/getlogin

And it seems to work and returns the correct result.

Is this the problem in your documention or is this something wrong how I am trying to access it?
