I want to execute a URL (Like curl_exec) in PHP according to the user’s response. Is it possible with the Telgram’s API? I didn’t find a way to do that.

I.E.: If a user click in confirm button, I execute a curl_exec with a url+token to confirm the booking to this user in my db (server side).

My bot code is:

     <?php          define('BOT_TOKEN', '00000000:0000000000000');     define('API_URL', 'https://api.telegram.org/bot'.BOT_TOKEN.'/');          function processMessage($message) {       // process the message received       $message_id = $message['message_id'];       $chat_id = $message['chat']['id'];       if (isset($message['text'])) {                  $text = $message['text'];//text received              if (strpos($text, "/start") === 0) {             //send the message to the user           sendMessage("sendMessage", array('chat_id' => $chat_id, "text" => 'Hi, '. $message['from']['first_name'].
