Answer 1

After receiving the callback_query, you need to send answerCallbackQuery:
$data = array(
'callback_query_id' => $callback_query_id,
'text' => $text,
'show_alert' => $show_alert,
'url' => $url) You
only need to specify $ callback_query_id, which comes in the message callback_query ({... "callback_query": {"id": "2322240909682341861" ...)))
