Are there specific permissions or access token requirements needed to retrieve certain data from Facebook posts using the Graph API in PHP?

To retrieve certain data from Facebook posts using the Graph API in PHP, you will need to obtain the necessary permissions and access tokens. This typically involves creating a Facebook App, obtaining an access token with the required permissions, and then using that token to make API requests. You may need permissions such as "pages_read_engagement" or "user_posts" depending on the data you are trying to access.

<?php
$accessToken = 'YOUR_ACCESS_TOKEN';

// Make a GET request to retrieve data from a Facebook post
$url = 'https://graph.facebook.com/{POST_ID}?fields=message,created_time&access_token=' . $accessToken;
$response = file_get_contents($url);
$data = json_decode($response, true);

// Output the retrieved data
echo 'Message: ' . $data['message'] . '<br>';
echo 'Created Time: ' . $data['created_time'];
?>
