Auto post to Facebook page

auto_post.php

<?php
require_once __DIR__ . '/vendor/autoload.php';

use Facebook\Authentication\AccessToken;
use Facebook\FacebookApp;
use Facebook\FacebookRequest;

session_start();

$app_id = '{APP ID}';
$app_secret = '{APP SECRET}';

$app = new FacebookApp($app_id, $app_secret);

$fb = new Facebook\Facebook(array(
    'app_id' => $app_id,
    'app_secret' => $app_secret,
    'default_graph_version' => 'v2.5',
));

//Page access token has been got from get_page_access_token.php
$access_token = '{PAGE ACCESS TOKEN}';
 
$page_id = '{PAGE ID}';

$post_data = array(
	'message' => '{Your message data here}'
	);

$request = new FacebookRequest($app, $access_token, 'POST', '/' . $page_id . '/feed', $post_data);

// Send the request to Graph
try {
  $response = $fb->getClient()->sendRequest($request);

  $graphNode = $response->getGraphNode();

  echo 'Post ID: ' . $graphNode['id'];

} catch(Facebook\Exceptions\FacebookResponseException $e) {
  // When Graph returns an error
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // When validation fails or other local issues
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

Question: Is it possible to use this to post to the Facebook Marketplace?

is this working until now?
any updates?
