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"
}
}
}

note The full stack trace of the root cause is available in the JBoss Web/2.1.3.GA logs.
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.
