How to create users through postman in uipath

I am trying to use postman to test api for creating users. As of now, I have tried to get the user data which was a success and tried to use swagger to fill up the post user that is create but the problem I am facing is that post user is giving 400 response that is bad response. First I thought it was syntax error but I have tried it many times now and no syntax errors are displayed. Maybe i am missing some important values can someone please help me.

Thanks a lot.
