Hi,

I am trying to send a push notification to BlackBerry devices using the BES's post service.

The Code is something like this:

System.Net.WebRequest req = System.Net.WebRequest.Create(ConfigurationManager.AppSettings["BESURL"] + userEmailID +
"&PORT=" + ConfigurationManager.AppSettings["BBAPPID"] + "&REQUESTURI=/");

List<Titles> Titles = new List<Titles>();
Titles title = new Titles();
title.title = sampleString;
Titles.Add(title);

string st = JsonConvert.SerializeObject(Titles);

req.Method = "POST";
req.ContentType = "application/json";
byte[] sentData = Encoding.UTF8.GetBytes(st);
req.ContentLength = sentData.Length;
using (System.IO.Stream sendStream = req.GetRequestStream())
{
sendStream.Write(sentData, 0, sentData.Length);
sendStream.Close();
}
System.Net.WebResponse res = req.GetResponse();

If I send the Same Request using the POSTMAN client with relevant Payload, it works.

Can someone please help?

This seems to be an issue with making POST request. I had the same problem and solved it as below

1) Convert WebRequest to HttpWebRequest
HttpWebRequest req = (HttpWebRequest)System.Net.WebRequest.Create(ConfigurationManager.AppSettings["BESURL"] + userEmailID +
 "&PORT=" + ConfigurationManager.AppSettings["BBAPPID"] + "&REQUESTURI=/");
  
2) Send credentials to the request using Credentials property
    req.Credentials = CredentialCache.DefaultCredentials;

3) Set Expect100Continue header to false
   req.ServicePoint.Expect100Continue = false
   More info about this header:

Hope this solves your issue.
