at last searching , gathering data

facebook post model json data

{ "entry": [{      "messaging":[{         "sender": {           "id": "1126306517444636"         },         "recipient": {           "id": "514501872066958"         },         "timestamp": 1469541638971,         "message": {           "mid": "mid.1469541638961:5d5d5d5bf1194eb824",           "seq": 64,           "text": "hi"         }          }         ]    } ] } 

so have create model

public class sender {    public string id { get; set; } }  public class recipient {     public string id { get; set; } }  public class message {     public string mid { get; set; }     public int seq { get; set; }     public string text { get; set; } }  public class messaging {     public sender sender { get; set; }     public recipient recipient { get; set; }     public long timestamp { get; set; }     public message message { get; set; } }  public class entry {     public list<messaging> messaging { get; set; } }  public class rootobject {      public list<entry> entry { get; set; } } 

and in controller class

public actionresult webhook(rootobject model) {     .................................... }
