    Subscriptiondetails.api = "depositmobilemoney";
    Subscriptiondetails.msisdn = "Phones.Text";
    Subscriptiondetails.amount = 10000;
    Subscriptiondetails.narration = "Subscription";

    Subscriptiondetails.status_notification_url = "http://108.175.14.205/SMISApi/api/smis/subscriptionresponse";
    System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
    string json = serializer.Serialize(Subscriptiondetails);
