Facebook Messenger API: Trouble setting up a webhook
I am trying to set up a web hook for the new Facebook Messenger bot platform on my PHP webserver and am receiving this error:
The URL couldn't be validated. Response does not match challenge, expected value = '364011207', received='

Any help is greatly appreciated.
Answer
I came across a fix. I scrapped my js attempt and created a new php file with the following code:
<?php
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'my_token_code') {
echo $challenge;
}
I got this code from the first 10 minutes of this video: https://www.facebook.com/marketingdevelopers/videos/883648801749520/
