Does an external application using BC webservices (such odata) need to have a user licence in BC? When trying to connect to ODATA from Excel (for example) I need to autenticate with a user and a password...
You can use for free an External user license, intended for customers and vendors. External users cannot use any clients provided by the Microsoft Dynamics 365 Business Central Application Programming Interface (API), such as the Windows client, the Web client, the Windows, the iPad or iPhone app, or the Android application.
