I've tried to send notifications to subscription list, but I got nothing although it responds with success:
{"status":"success","request_id":"2405"}

And it does not tell me the rest of the result like the subscription IDs as in the documentation:
{
"status": 'success',
"request_id": 123,
"norecord": 4,
"norecord_list": [
"0001",
"0002",
"0003",
"0004"
]
}
