Facebook api: event url

let's say i know i have an event id. I need the event url (to link users to it), but the graph API doesn't seem to have it ( https://developers.facebook.com/docs/graph-api/reference/event/ ), for example if i use the command the GET /v2.9/310917539364835 HTTP/1.1

output is:

{
  "description": "...",
  "end_time": "2017-06-23T22:30:00+1000",
  "name": "UQ Postgrad Masquerade Party (End of Semester)",
  "place": {
    "name": "Cloudland",
    "location": {
      "city": "Brisbane",
      "country": "Australia",
      "latitude": -27.45891,
      "longitude": 153.0349699,
      "state": "QLD",
      "street": "641 Ann Street",
      "zip": "4006"
    },
    "id": "103221159774910"
  },
  "start_time": "2017-06-23T19:30:00+1000",
  "id": "310917539364835"
}

      

        
        
        
      

    

but the url is missing.

thank
