Reading and settings scores to facebook app / game and my Adobe’s FB API update

March 22nd, 2012 by Slav

Majority of the calls you would ever make to Facebook API require user access token. There are some however, that require app access token instead. These are normally calls you do on behalf of the app not user. An example of such situation would be creating a test users, or reading Insight data.

To my surprise app access token is also required when you want to read or set user scores.

For those who are not aware of this, you can set and read score value for an app user.  For this to work, you have to set the type of your application to “Game”, in the FB developers app general settings page.

As current Adobe’s Facebook API didn’t support making such calls, I modified the source code (for web development) so that it would.

Btw, if anybody from the Adobe’s Facebook API administrators is reading this, please feel free to include these changes in your next version. You can download the modified source  here.

So how do you use this ? Here is the example how to set and read user scores, and also how to read scores of the users’s friends that have played the app/game.

First of all in addition to app id you will also need to pass an application secret to the init function.

protected static const APP_ID : String = "YOUR APP ID GOES HERE";
protected static const APP_SECRET : String = "YOUR APP SECRET GOES HERE";

Facebook.init(APP_ID, handleInit, null, null, APP_SECRET);

App will now initialise and function handleInit() will only be called after app access token is received. Now you are ready to make calls that require app access token.

Let’s set some user scores first :

private function setScore() : void
     var randomScore : int = Math.random() * 10000; //just generate some random score number
     var params : Object = {score:randomScore};
     Facebook.api("/" + userFB_ID + "/scores", onScoreSubmitted, params, "POST", true);

notice the 5th argument, which is a boolean switch “use app access token” set to true. By default it is false. Without this call would use user access token and the whole operation would fail.

userFB_ID is facebook user id, which you can get from the auth object at the login callback, or anytime by calling Facebook.getAuthResponse().uid

Ok, this is how you can read scores of the user that’s currently logged in :

private function readScore() : void
     Facebook.api("/" + userFB_ID + "/scores", onScoresRead, null, null, true);
private function onScoresRead(response : Object, fail : Object) : void
 var username : String = response[0];
 var appName : String = response[0];
 var score : String = response[0].score;
 trace(username + " score for app " + appName + " is " + score);

Again as with setting the score, reading also requires fifth argument be set to true. Response object will contain array of score object for different games (if user played more then one game) .. in my example I am assuming just one game.

Very useful functionality is finding out the score values for user friends that have also played the game. This is useful for building leader boards for the game that has friends scores on it as it makes it more personal and motivate user to beat his friends – thus play your game more. For this to work you have to ask a permission : “friends_games_activity” at the login stage.

Here’s the script :

private function readAppScores() : void
    Facebook.api("/" + APP_ID + "/scores", onAppScoresRead);
private function onAppScoresRead(response : Object, fail : Object) : void
 if (response)
 var players_arr : Array = response as Array;
 output("High Scores are : \n");
 for (var i : int = 0; i < players_arr.length; i++)
 var username : String = players_arr[i];
 var score : String = players_arr[i].score;
 trace(username + " score is " + score+"\n");

Interestingly for this functionality you have to use user access token not app access token. The callback returns array of objects containing information about app, user and scores.

    Thank you very much for the modified Facebook API code. I hit a roadblock with the APP secret but now with your code it works just fine!

  2. Armand

    I read more into this issue and I came to the conclusion that the approach is wrong.

    From the FB dev:
    As Application Access Tokens are built off the Games client secret, which is a shared secret between Facebook and the app, these should not be stored client side to protect their integrity. We will keep our Application Access Token on our web server and write a small PHP script that will POST scores.

    So that’s why there is no support for App Access Tokens in the Facebook API – because it requires us to embed the App Secret inside the swf, which would pose a security risk.

    The only proper way to do this is server-side.
