what i tried
the below code is my webhook endpoint
- it responds to the validation request
- and it generates and stores a timestamp into a file called "GTest.txt" each time a request is sent to this function/corresponding route
public function webhook_endpoint()
{
$report_object = new report;
$result = "";
$file_content_prefix = "";
if (isset($_GET['challenge'])) {
$result = $_GET['challenge'];
$file_content_prefix = "Challange";
} elseif ($report_object->webhook_endpoint_authenticate() == 1) {
$file_content_prefix = "Authenticated";
} else {
header('HTTP/1.0 403 Forbidden');
$file_content_prefix = "Not authenticated";
}
$timestamp = date('Y-m-d h:i:s a', time());
$file_content = $file_content_prefix." ".$timestamp;
$file_name = "GTest.txt";
file_put_contents($file_name, $file_content);
return $result;
}
problem
- It validates and generates a timestamp for that request just fine
- but when i change a file in the app's dropbox folder it doesnt generate any new timestamps in my "GTest.txt" file which leads me to believe no webhook request was sent
- i'm editing the dropbox file both on my desktop and on dropbox online (i edited a test files content and name and also added a .png file) but no webhook request seemed to have sent. 
P.s
is this a glitch? if so please explain why this kind of glitch would happen?
