Tell about the integration of 1C with other systems. What have you integrated through what?

Integration of 1C with other systems often relies on data exchange through various protocols and formats: XML, JSON, CSV, as well as web services (SOAP, REST), COM connections, or direct database access.

Most commonly, 1C is integrated with:

• CRM systems (e.g., Bitrix24, Salesforce) for synchronization of clients and orders;
• ERP and warehouse systems for inventory and goods movement exchange;
• banking systems for automating payments and statements;
• websites and online stores for catalog updates and order processing;
• electronic document management systems for exchanging invoices, waybills, and acts.

Example: via REST API, 1C receives orders from an online store, processes them, and then sends back statuses and delivery information.

File exchange via FTP or network folders is also frequently used, where 1C periodically reads or exports data.
