Architecture & Data Flow

The Shopware 6 API Connector connects Business Central as the leading ERP system with Shopware 6 as the online shop. Communication takes place exclusively through the Shopware Admin API (REST) using a bearer token.

Roles of the systems

• Business Central is generally the leading data source for items, prices, inventory, and customers.
• Shopware 6 is the sales front end and returns orders.

Data flow

What is transferred in which direction?

Object	Direction	Trigger
Items, pictures, attributes, categories	BC → Shopware	Upload (manual / scheduled)
Prices & price lists	BC → Shopware	Upload (manual / scheduled)
Inventory	BC → Shopware	Upload (manual / scheduled)
Customers & B2B users	BC → Shopware	Upload (manual / scheduled)
Orders	Shopware → BC	Download (manual / scheduled)
Shipment/invoice status	BC → Shopware	when posting
PDF documents	BC → Shopware	Upload (Premium)

Mappings as the connecting element

So that BC values and Shopware values find each other, the connector maintains mappings – for example for taxes, payment methods, currencies, and sales channels. These are filled once through Load Shopware Initial Data and maintained in the Shopware Assignment & Mapping section.

Logging

Every API call can be logged. Business events end up in the Activity Log, and technical details (with the Developer Log) in the API Call Log.
