I have some resource- UserProfile

```
public UserProfile
{
   public string Email{get;set;}
   public string Password{get;set;}
}

```

I want to change Email and Password separatly (only one for user at same time). I have web api controller for example /api/user/123 that handle requests in RESTful style. Follow the RESTful style i should have **one** method **PUT** which update the resource, but i have two task that update the same resource api/user/123. I need to add some feature to PUT request body like
{email:'test@domain.com', **changeType:'email**'} or {password:'12345678',**changeType:'password'** } to write some if in my PUT method ? Or there is some other way to update my resource in RESTful style ?
