        var accessToken = "";
        var accessTokenSecret = "";
        // this two tookens you will get from URL on the same above page
        var realmId = "1400728630";   //1400728630
        // this is youre company ID which can be used when you create youre          //company on freshbook
        var serviceType = IntuitServicesType.QBO;

        var validator = new OAuthRequestValidator(accessToken, accessTokenSecret, consumerKey, consumerSecret);
        var context = new ServiceContext(appToken,realmId, serviceType, validator);
        var service = new DataService(context);


        try
        {
            Customer customer = new Customer();
            //Mandatory Fields
            customer.GivenName = "Mary";
            customer.Title = "Ms.";
            customer.MiddleName = "Jayne";
            customer.FamilyName = "Cooper";
            service.AddAsync(customer);
            //service.Add(entity);
        }catch(Exception ex)
        {
            System.Console.WriteLine(ex);
        }
