Can Dynamics 365 Business Central be connected both cloud and on-premises?

Yes, we support both operating models. We connect the cloud version of Dynamics 365 Business Central via the standardized REST and OData APIs with authentication through Azure AD. The on-premises variant additionally offers SOAP web services and sometimes direct access to extended endpoints, which helps with custom adaptations.

The key point: these differences stay hidden behind the middleware. The shop adapter and business logic see the same uniform interface for both deployment variants. If you later migrate from on-premises to the cloud, only the Dynamics connector needs swapping, not the shop connection. That keeps your integration independent of future operating decisions.
