Question

I am currently building an application which also allow users to specify their profile URLs for the various social network such as Facebook, Twitter, Google+ and etc. I will focus this question on Facebook instead for the start.

To allow users to easily input their profile links easily, I will like to have a button on their “Settings” page which they will login to their Facebook account, select the page or profile and it will automatically fill in the Textfield.

I’m new to FB and other social network APIs. It will be good if there is some samples or a documentation I can read up. I’ve spend sometime on the documentation but don’t find anything that mention this.

Answer 1

A simple Graph API request gives you the user profile link.

/me?fields=link

Result:

{
  "link": "https://www.facebook.com/profile.php?id=XXXXX", 
  "id": "XXXXX"
}, 
{
  "link": "https://www.facebook.com/first.last", 
  "id": "YYYYY"
}
