How to get user's location from Facebook chatbot api

Question

I was wondering how I could get a user's location from a Facebook messenger chatbot. What I want to accomplish is the following: the chatbot will say something like "Please send me your location", and then the user would tap the "Share Location" on the Facebook messenger app. I have figured out how to get a textual message that the user sends, but not the location. Thanks in advance!

Location can be obtained as well as text. More precisely, as the photo. You need take message.attachments.payload.coordinates. Also you can check message.attachments.type.

example:

{
   "object": "page",
   "entry": [{
       "id": "1719442148306048",
       "time": 1466780344978,
       "messaging": [{
           "sender": {"id": "123456789"},
           "recipient": {"id": "987654321"},
           "timestamp": 1466780344847,
           "message": {
               "mid": "mid.12345698875:c80066d69b6cee1779",
               "seq": 65,
               "attachments": [{
                   "title": "Dmitry's Location",
                   "url": "Link to bing.com through facebook redirect"
                   "type": "location",
                   "payload": {"coordinates": {"lat": 55, "long": 37}}
               }]
           }
       }]
   }]
}
