How to write custom Bitrix24 activity

How to write custom business-process activity for cloud version Bitrix24? 8 Simple Steps - for memory:

1) Create application structure

<?php
$protocol=$_SERVER['SERVER_PORT']=='443'?'https':'http';
$host=explode(':',$_SERVER['HTTP_HOST']);
$host=$host[0];
define(‘BP_APP_HANDLER',$protocol.'://'.$host.$_SERVER['REQUEST_URI']);
header('Content-Type: text/html; charset=UTF-8');
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<script src=«//api.bitrix24.com/api/v1/"></script>
</body>
</html>

2) Check and process data

<?php
function clean($value = "") {
$value = trim($value);
$value = stripslashes($value);
$value = strip_tags($value);
$value = htmlspecialchars($value);
return $value;
}
?>
<?php
function check_length($value = "", $min, $max) {
$result = (mb_strlen($value) < $min || mb_strlen($value) > $max);
return !$result;
}
?>

3) Using Bitrix24 REST-api on php

<?
function callB24Method(array $auth, $method, $params){
$c=curl_init('https://'.$auth['domain'].'/rest/'.$method.'.json');
$params["auth"]=$auth["access_token"];
curl_setopt($c,CURLOPT_RETURNTRANSFER,true);
curl_setopt($c,CURLOPT_POST,true);
curl_setopt($c,CURLOPT_POSTFIELDS,http_build_query($params));
AddMessage2Log($c, "demo_user_info");
$response=curl_exec($c);
AddMessage2Log($response, "demo_user_info");
$response=json_decode($response,true);
return $response['result'];
}
?>
<?php
$user_info=callB24Method($auth,'user.get',array(
‘ID’=>$ID
)
);?>

4) Method of Bitrix24 application debugging

<?php
define("LOG_FILENAME", $_SERVER[«DOCUMENT_ROOT»].»/__log_castom1_".date("Ymd").".txt»);
AddMessage2Log($user_info, "demo_user_info");
?>

5) Using Bitrix24 REST-api on javascript

BX24.callMethod(
'bizproc.activity.add',
params,
function(result)
{
if (result.error())
alertify.alert('Error: '+result.error());
else
alertify.alert('Installation successfully completed');
}
);

6) Creating and deleting simple activity for cloud Bitrix24

BX24.init(function()
{
});
function installActivity1()
{
var params={
'CODE':'user_additional_info',
'HANDLER':'<?=BP_APP_HANDLER?>',
'AUTH_USER_ID':1,
'USE_SUBSCRIPTION':'Y',
'NAME':'Additional information from users card',
'DESCRIPTION':'Aktivity gets information from the user cards',
'PROPERTIES':{
'User':{
'Name':'User',
'Type':'user',
'Required':'Y',
'Multiple':'N',
},
},
'RETURN_PROPERTIES':{
'PERSONAL_MOBILE':{
'Name':'Users_PERSONAL_MOBILE',
'Type':'string',
'Required':'N',
'Multiple':'N',
},
'WORK_POSITION':{
'Name':'Users_WORK_POSITION',
'Type':'string',
'Required':'N',
'Multiple':'N',
},
'UF_SKYPE':{
'Name':'Users_UF_SKYPE',
'Type':'string',
'Required':'N',
'Multiple':'N',
},
}
}
BX24.callMethod(
'bizproc.activity.add',
params,
function(result)
{
if (result.error())
alertify.alert('Error: '+result.error());
else
alertify.alert('Installation successfully completed');
}
);
}
 
function uninstallActivity1(){
var params={
'CODE':'user_additional_info'
}
BX24.callMethod(
'bizproc.activity.delete',
params,
function (result)
{
if (result.error())
alertify.alert('Error: '+result.error());
else
alertify.alert('Uninstallathion successfully completed');
}
);
}

7) Logging of requests and responses on javascript

BX.ajax.get('/b24/ajax/js_request_log.php', {
params
});
Logger:
<?php
require($_SERVER['DOCUMENT_ROOT'].'/bitrix/modules/main/include/prolog_before.php');
define('LOG_FILENAME', $_SERVER['DOCUMENT_ROOT'].'/ajax/js_error.txt');
$request = \Bitrix\Main\Context::getCurrent()->getRequest();
if ($request->get('data')) {
AddMessage2Log(print_r($request->get('data'), true));
}
?>

8) Return answer to business process

<?php
callB24Method($auth,'bizproc.event.send',array(
"EVENT_TOKEN"=>$event_token,
"RETURN_VALUES"=>array(
'PERSONAL_MOBILE'=>$user_info[0]['PERSONAL_MOBILE'],
'WORK_POSITION'=>$user_info[0]['WORK_POSITION'],
'UF_SKYPE'=>$user_info[0]['UF_SKYPE'],
),
"LOG_MESSAGE"=>'OK'
));
?>

As you can see, the href for the link is set as "#" - clicking on this link is processed by the JS code from the script.js of this component. Indeed, the BX.CrmTimelineMenuBar function is responsible for this.processItemSelection()....
