The chatId variable is a general way to get ChatApp client data. Some messengers don't have phone numbers (TelegramBot, ViberBot, Instagram, Facebook*, VK, Avito). Then you can start a dialogue via Bitrix24 webhook by getting the ChatId of the ChatApp client.

While there was no dialogue with the client, the variable cannot be used.
