Website and Bitrix24 integration

Website https://www.real-estate.am/

On it, objects are entered into the admin panel (object cards are filled in).

It is necessary to integrate the site with Bitrix24 (boxed version) according to the following scenario:

In Bitrix24, object cards will be stored in smart processes.
1. Perform the initial synchronization of objects (from the site to Bitrix24).
2. When creating a new object in Bitrix24 and switching to a certain status (in smart processes), the object is added to the site. When changing the status of sold, etc., the object is removed from publication on the site.
