How do I change a users password using restman api ?

For password change, call of the Restman api, needs the "body" to be the actual raw text of the password (or the hash) - it is in raw bytes/character NOT in xml format as would have expected from the other parts of the API. 
 

API Gateway 9.3

RESTman example : 

https://odoma04-gw.example.com:8443/restman/1.0/users/20b28e068d1cae807d2fd5aef7360a95/password?format=plain 

The "body" is raw password - so all the POST data is taken as the "password" : in my case :
