When creating a lead, you need to check for the existence of leads with the same Email. How to do this if the array returned by the CCrmLead::GetList (CCrmLead::GetListEx) methods does not contain an email or fm field?

Answer 1

Let's do it a little differently:
Examine the following code and the crm.duplicate.findbycomm rest method. See /home/bitrix/www/bitrix/modules/crm/classes/general/restservice.php

use \Bitrix\Main;
use \Bitrix\Crm;

/* @var string Email, который будем искать */
$sEmail = '[email protected]';

/* @var array ID лидов, которые попадаются под условия */
$arLeadIds = [];

if ( Main\Loader::IncludeModule('crm') )
{
  // Формируем критерий, подсовываем Email
  $criterion = new Crm\Integrity\DuplicateCommunicationCriterion( Crm\CommunicationType::EMAIL_NAME, $sEmail);

  // Выполняем поиск первых 20 клиентов
  $duplicate = $criterion->find( \CCrmOwnerType::Lead, 20);

  // Если найдены entity проитерируем их
  $entities = $duplicate->getEntities();
  if ( !empty($entities) )
  {
    foreach($entities as $entity)
    {
      $arLeadIds[] = $entity->getEntityID();
    }
  }
}

// А тут будут ID сделок
var_dump($arLeadIds);
