Question

Is it possible to get a Facebook user’s name from their Facebook Id number with a graph call?
If so, does anyone know the call?

For example you can get a user’s picture by making the following call

  "http://graph.facebook.com/" + someUserId + "/picture"

Answer 1

Simply querying the Graph API with the user_id should be enough to get the name of the user –

http://graph.facebook.com/4

{
  "id": "4", 
  "name": "Mark Zuckerberg", 
  "first_name": "Mark", 
  "last_name": "Zuckerberg", 
  "link": "https://www.facebook.com/zuck", 
  "username": "zuck", 
  "gender": "male", 
  "locale": "en_US", 
  "updated_time": "2012-05-20T01:29:18+0000", 
  "type": "user"
}

You could drill down even more by adding a filter for the name field –

{
  "name": "Mark Zuckerberg", 
  "id": "4", 
  "type": "user"
}
