Solution

Only way that i had found is to use returnurl parameter to receive the response.

You need to build service/controller that will receive the data from response and send it back to your page.

This is how i did it:

My returnurl send data to my controller,i work with this data ,and then i send request to my page with query-string that i have build from pay pal data that i had received,and read it on my page (PageLoad event)

This is not the best way ,but it working.If you have another way to do this please let me know.

 public void PayPalLisiner()
    {
        try
        {
       //get pay pal data
       string AuthorizationCode = HttpContext.Current.Request.QueryString["code"];

      //my function that work with data,and prepare query-string 
      string PayPalLogin = privateZoneService.PayPalLogin(AuthorizationCode);

      //set request with query-string parameters
      HttpContext.Current.Response.Redirect("http://demo.com/login?PayPalLogin=" + PayPalLogin);
        }
        catch (Exception ex)
        {
            Logger.Error(ex.Message);
        }

    }
