Posting facebook api not as page - facebook

Question

I've made facebook app, got appID and secret, and I am trying to post to a page as the page. I've granted the app permission.
But when I'm posting, new post creates "as user", not as page.
My code:
require '../lib/fb/autoload.php';
use Facebook\FacebookSession;
use Facebook\FacebookRequest;
use Facebook\GraphUser;
use Facebook\FacebookRequestException;
FacebookSession::setDefaultApplication('APP_ID','SECRET');
$session = new FacebookSession('ACCESS_TOKEN');
try {
$response = (new FacebookRequest(
$session, 'POST', '/1429642034012499/feed', array(
'message' => 'test',
'link' => 'http://mylink',
)
))->execute()->getGraphObject();
print_r($response);
} catch (FacebookRequestException $e) {
echo "Exception occured, code: " . $e->getCode();
echo " with message: " . $e->getMessage();
} catch (\Exception $e) {
}
Page to view.

This Answer is for C#, using the .NET Facebook API Library. But Logic should be same in PHP.
You have to get the Page Access Token:
Go Here: developers.facebook.com/tools/
Then Go to this Link:
Then Click on: "Get Access Token"
Then Add these Permissions:
Then Copy New access Token:
Now in C# Class I do (This is the POST A Comment as Page):
var userClient = new FacebookClient("THE NEW ACCESS TOKEN YOU JUST GENERATED");
dynamic accountInfo = userClient.Get("USER_ID" + "/accounts");
//USER_ID Should be Digits, this is the UserID when you do: facebook.com/USERID it should come up with the Admin Profile
var pageAccessToken = accountInfo.data[0].access_token;
var pageClient = new FacebookClient(pageAccessToken);
dynamic parameters = new ExpandoObject();
parameters.message = model.Message;
dynamic pageResult = pageClient.Post(string.Format("{0}/comments",), parameters);
