Site integration on Bitrix and MySclad

Currently, the site is working in a team with RetailCRM and MySclad. Integration has been in place since 2017. The loading of goods in the current integration was from Bitrix, after the goods automatically befriended in the SRM and further to The MoySclad. Now we need to remove the system from this link and make integration only between Bitrix and MySclad. Loading goods into the system should be through MySclad, not Bitrix as it was before.
