I used to be able to go to my Facebook profile page https://www.facebook.com/{Username} and replace the "www" for "graph" https://graph.facebook.com/{Username}.
The answer to that used to be my real facebook ID and some other info, but now I get:
{
"error": {
"message": "(#803) Cannot query users by their username ({Username})",
"type": "OAuthException",
"code": 803
}
}
Yesterday I made the exact same thing and it worked, but today it doesn't. Is there any other way of finding my ID? Does it work for anyone?
