Bitrix24 Bot Platform

To illustrate a fully functional, yet simple bot, we are going to create application that informs users of their overdue tasks. Our chatbot will recognize only one command: what's hot. The range of recognized commands can be extended anytime to get any kind of reports directly to the Bitrix24 chat.

Example of a simple chatbot:

<?php
/**
 * Simple and handy reporting chatbot for bitrix24
 */

$appsConfig     = array();
$configFileName = '/config_' . trim(str_replace('.', '_', $_REQUEST['auth']['domain'])) . '.php';
if (file_exists(__DIR__ . $configFileName)) {
   include_once __DIR__ . $configFileName;
}
// receive event "new message for bot"
if ($_REQUEST['event'] == 'ONIMBOTMESSAGEADD') {
   // check the event - register this application or not
   if (!isset($appsConfig[$_REQUEST['auth']['application_token']])) {
      return false;
   }
   // response time
   $arReport = getAnswer($_REQUEST['data']['PARAMS']['MESSAGE'], $_REQUEST['data']['PARAMS']['FROM_USER_ID']);
   $arReport['attach'][] = array("MESSAGE" => 'As soon as you're through with these tasks, just ask me [send=what's hot]What's hot?[/send] again – I'll give you more to have on your plate!');
   
   // send answer message
   $result = restCommand('imbot.message.add', 
      array(
         "DIALOG_ID" => $_REQUEST['data']['PARAMS']['DIALOG_ID'],

         "ATTACH"    => array_merge(
            $arReport['attach']
         ),
      ), 
      $_REQUEST["auth"]);

} // receive event "open private dialog with bot" or "join bot to group chat"
else {

      // check the event - register this application or not
      if (!isset($appsConfig[$_REQUEST['auth']['application_token']])) {
         return false;
      }
