Why aren't viber message hooks coming?

Question

PHP

Good afternoon.
I did everything according to the instructions and this
Registration of the token passes, I get the reverse hook.

(
  'event' => 'webhook',
  'timestamp' => '1498367143639',
  'message_token' => '****')

But when someone writes to the public, or enters or exits, there are no hooks.
What could be the problem?
Thanks

Do you track events? For example:

....
$request = file_get_contents("php://input");
$input = json_decode($request, true);
  
  if ($input['event'] == 'message' ) {		
  //какие-то действия
  }elseif ($input['event'] == 'delivered') {
.....
