How can I get referral ref value from facebook post webhook inside RASA actions and store it in slots?

```auto
{
    "object": "page",
    "entry": [
        {
            "id": "307222070135630",
            "time": 1569345841955,
            "messaging": [
                {
                    "sender": {
                        "id": "2233033630067080"
                    },
                    "recipient": {
                        "id": "307222070135630"
                    },
                    "timestamp": 1569345841730,
                    "postback": {
                        "title": "Get Started",
                        "payload": "WELCOME_MESSAGE",
                        "referral": {
                            "source": "SHORTLINK",
                            "type": "OPEN_THREAD",
                            "ref": "12345678"
                        }
                    }
                }
            ]
        }
    ]
}

```

Got it. I think I just need to modify this file /Users/me/anaconda/envs/BotDev/lib/python3.6/site-packages/rasa/core/channels/facebook.py
