APNs Payload

[JDandini]

Hi Friends, I'm new at my current job, they ask me to check some if we can store an element who comes from the push notification sent by localytics, the thing is I have no access to the panel, so they just send the push notification and expect to parse the response, as I said since I have no access to the panel so I can't follow the tutorial, I can achieve this if I can know where is the custom key/values are set on the payload, I mean there are two options
1st the key values are inside the aps dictionary making it look like this:

{"aps" : {
   "message" : "some message",
   "badge" : 1,
   "key" : "value"
 }
}

Or the key/value are at the same level as the aps dictionary making look like this:

{"aps" : {
   "message" : "some message",
   "badge" : 1
 },
 "key" : "value"
}

If you can help me I appreciate, I mean I try anything and I'm desperate
