Xtify Payload - Server Error

Question

I am attempting to send a push notification to both android and iOS using xtify. I am able to do this, however, the payload information doesn't appear to be working for me. If I remove the payload, the request succeeds, but adding the payload causes a server error. Can anyone look at the json I am sending and tell me if I am doing something wrong?

{
   "apiKey":"...",
   "appKey":"...",
   "xids":[
      "..."
   ],
   "content":{
      "subject":"chat from billy bob",
      "message":"hey",
      "payload":{
         "UserId":"1",
         "DeviceId":"9"
      }
   }
}

Here is the error the server returns: HTTP/1.1 500 Internal Server Error Date: Wed, 30 May 2012 22:51:51 GMT Content-Type: text/html;charset=utf-8 Content-Length: 5839 Connection: close

Answer 1

The element type is JSON and not an array. So the payload element should look like:

"payload": "{ 'key1' : 'value1', 'key2' : 'value2'} "

Give that a try and let me know how it works out.
