Question

I've found an interesting app . This fb-app get all likes from any fanpage and sort it by mass and country!

My question:

how do these app get the data from the graph api ?

First: get the fanpage-object no access token needed

https://graph.facebook.com/cocacola/

{
   "about": "The Coca-Cola Facebook Page is a collection of your stories showing how people from around the world have helped make Coke into what it is today.",
   "checkins": 146,
   "description": "Created in 1886 in Atlanta, Georgia, by Dr. John S. Pemberton, Coca-Cola was first offered as a fountain beverage at Jacob's Pharmacy by mixing Coca-Cola syrup with carbonated water. \n\nCoca-Cola was patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States. In 1899, The Coca-Cola Company began franchised bottling operations in the United States. \n\nCoca-Cola might owe its origins to the United States, but its popularity has made it truly universal. Today, you can find Coca-Cola in virtually every part of the world.\n\nCoca-Cola Page House Rules: http://CokeURL.com/q28a",

      },

     "offset_y": 0
  }
}

second: get the likes from the facebook object:

https://graph.facebook.com/cocacola/likes?access_token=xxxxxxx

now i will receive all fan-page which "cocacola" like, but i need all users which like cocacola!

Maby its only possible with FQL Query ?

Answer 1

With FB 2.6 API you can get total likes with fan_count field.

http://graph.facebook.com/cocacola/?fields=fan_count&access_token={value}

Answer 2

Facebook will not give you a list of users who like a page. You don't need this to create this app. You can get this data by querying publicly available insights data.

This URL will get you the raw data this app uses to create this graph:

https://graph.facebook.com/cocacola/insights/page_fans_country?access_token=XXXXXX

You can get this information with any valid access_token.

Answer 3

https://graph.facebook.com/cocacola/?fields=fan_count&access_token=#######

You can get the facebook page member likes using the field fan_count. But you have to pass page access token rather than the user access_token.
