        request4.AddHeader("Authorization", "Bearer " + mytoken);
        request4.AddParameter("application/json", "{ \"active\": true }", ParameterType.RequestBody);


        var result = client4.Execute<List<RootObject>>(request4);//getting nullexcception here

        //Console.WriteLine(result);
        //Console.ReadKey();

        {
            foreach (var j in i.sales_offices)
            {
                Console.WriteLine(j.state);
            }
}

        }


    public class SalesOffice
    {
        public bool active { get; set; }
        public string _id { get; set; }
        public string name { get; set; }
        public string state { get; set; }
    }


public class RootObject
      {
          public bool success { get; set; }
          public string message { get; set; }
          public List<SalesOffice> sales_offices { get; set; }

      }
and from json I'm getting this result

{ "success": true, "message": "Gtm Cities loaded successfully!", "sales_offices": [ { "active": true, "_id": "XXXXX5cb57542ed50d82730d7661d", "name": "UAXXS", "state": "AXXX.P" }

Please help me as it is showing no issue in the code

This

var result = client4.Execute<List<RootObject>>(request4);

looks incorrect - you are not returning a list of RootObjects, you're (hopefully) returning a RootObject hierarchy that has within it, a list of SalesOffice(s)

Your data shows that at least you're getting a SalesOffice, I'm not sure/it's not clear if that's just a snippet of data you've shown or the entire return - If result is being populated correctly, then, I would expect to access the first sales_office by something like:

SalesOffice soFirst = result.sales_offices.first();

btw 'RootObject' as you have defined does not have a 'Data' field/element, so this wont work - I suspect what you meant was more along the lines of

foreach (var j in result.sales_offices)
{
    Console.WriteLine(j.state);
}

I must admit, I hate the use of 'var j' there, since you know it's type ie 'SalesOffice' .. overusing var makes code hard to read
