How to get page events from Facebook? - facebook

Question

I'm using this code, but it returns empty data array. My access_token has all permissions. I know PAGE_ID, now i need to get events from this page.Thanks
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : APP_ID, // App ID
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional initialization code here
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
var interval = setInterval(function() {
if (typeof FB != 'undefined') {
clearInterval(interval);
FB.api('/' + PAGE_ID +'/events?access_token=' + ACCESS_TOKEN, function(response) {
//do something with response
});
}
}, 20);
</script>

It's not clear from your code how you are obtaining the access_token - are you using the access token for the page\account for which you need to retrieve the events? The way I have been doing it (not sure where I picked up this technique) for page events is to loop through the user accounts to get the access token for the page in question. Something like this (php)
$accounts = $facebook->api('/me/accounts');
foreach($accounts['data'] as $account){
if($account['id'] == $page_id){
$page_access_token = $account['access_token'];
}
}

My first access_token for my APP which i get from http://developers.facebook.com/tools/explorer/ was wrong. (Maybe it's only for test mode) Because i couldn't get events by this access_token.
On http://developers.facebook.com/docs/authentication/applications/ was written:
App Access Tokens generally do not expire. Once generated, they are valid indefinitely.
To obtain an App Access Token, perform an HTTP GET on:
https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials
I got access_token using HTTP GET, by this access_token i get events from facebook page: https://graph.facebook.com/PAGE_ID/events
