    curl -X POST -H "Authorization: Bearer <Bearer>" -H "Content-Type: application/json"
    -d '{

              "last_name" : "Harrys",
              "user_name" : "JHarrys",

One of the easiest ways to parse json data is to use Newtonsoft's Json library. You'll make a class that will hold the data you want to parse...

public class Movie {
public string Name {get;set;}
public string ReleaseDate {get;set}
...
}

Then you get your json string and Deserialize it with JsonConvert.

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

string name = m.Name;
// Bad Boys
