Facebook Messenger Chatbot how do I collect the users geo location that they send?

Question

In Facebook Messenger there is an icon allowing the user to send their geo coordinates.

Is this available on the Facebook Messenger platform yet i.e. if a user sends me their location does my Chatbot have access to it? If so how is it done because i can't see it in the response in my webhook.

Answer 1

You get the location as attachment in message. See sample below:

{ mid: 'mid.1463464074086:96b149e1a047e47842',
  seq: 2076,
  attachments: 
    [ { title: 'Anupam\'s Location',
   url: 'https://www.facebook.com/l.php?u=https%3A%2F%2Fwww.bing.com%2Fmaps%2Fdefault.aspx%3Fv%3D2%26pc%3DFACEBK%26mid%3D8100%26where1%3D19.120002%252C%2B72.863715%26FORM%3DFBKPL1%26mkt%3Den-US&h=AAQH523sr&s=1&enc=AZNmEBjv3zHHm0_dYnEIC6j7EDsJNt8PZRZZyaXbIZ6VzjPsQUOOaMIPGtXFH17CevUiNK0_K594CgDQHAMQSru7uS_jjbkxojBWNwBnncqzaw',
   type: 'location',
   payload: [Object] } ] }

From the payload, you can access the Latitude and Longitude using:

lat = event.message.attachments[0].payload.coordinates.lat
lng = event.message.attachments[0].payload.coordinates.long
