Question

I'm trying to send the following request: ``` POST /messaging/registrations/(REGISTRATION_ID_FOR_DESTINATION_APP_INSTANCE)/messages HTTP/1.1 Host: api.amazon.com Authorization: Bearer (MY_ACCESS_TOKEN) Content-Type: application/json X-Amzn-Type-Version: com.amazon.device.messaging.ADMMessage@1.0 Accept: application/json X-Amzn-Accept-Type: com.amazon.device.messaging.ADMSendResult@1.0 { "data":{"message":"value1","title":"value2"}, "consolidationKey":"Some Key", "expiresAfter":86400 } ``` in order to get a response format like this: ``` HTTP/1.1 200 X-Amzn-Data-md5: t5psxALRTM7WN30Q8f20tw== X-Amzn-RequestId: e8bef3ce-242e-11e2-8484-47f4656fc00d Content-Type: application/json X-Amzn-Type-Version: com.amazon.device.messaging.ADMSendResult@1.0 Content-Length: 308 {"registrationID":(REGISTRATION_ID_FOR_DESTINATION_APP_INSTANCE)} ``` to do that I tried with this code: ``` private void sendNotification(String registrationID,String message, String title,String accessToken) { //registrationID…

Accepted Answer

I found an other solution that work perfectly .

```
private void sendNotification(String registrationID,String message,String title,String accessToken)
    {
       HttpWebRequest httpWReq =
            (HttpWebRequest)WebRequest.Create("https://api.amazon.com/messaging/registrations/" + registrationID + "/messages");

Encoding encoding = new UTF8Encoding();
        string postData = "{\"data\":{\"message\":\""+message+"\",\"title\":\""+title+"\"},\"consolidationKey\":\"Some Key\",\"expiresAfter\":86400}";
        byte[] data = encoding.GetBytes(postData);

httpWReq.ProtocolVersion = HttpVersion.Version11;
        httpWReq.Method = "POST";
        httpWReq.ContentType = "application/json";//charset=UTF-8";
        httpWReq.Headers.Add("X-Amzn-Type-Version",
                                           "com.amazon.device.messaging.ADMMessage@1.0");
        httpWReq.Headers.Add("X-Amzn-Accept-Type",
                                        "com.amazon.device.messaging.ADMSendResult@1.0");
        httpWReq.Headers.Add(HttpRequestHeader.Authorization,
            "Bearer " + accessToken);
        httpWReq.ContentLength = data.Length;

Stream stream = httpWReq.GetRequestStream();
        stream.Write(data, 0, data.Length);
        stream.Close();

HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
        string s=response.ToString();
        StreamReader reader = new StreamReader(response.GetResponseStream());
        String jsonresponse = "";
        String temp = null;
        while ((temp = reader.ReadLine()) != null)
        {
            jsonresponse += temp;
        }

}
```
