If the machine is to be used with the API or an interface, a separate interface user must be created for this purpose. This interface user can be created at global or local level. For security reasons, it is recommended that the interface user be given only the required rights. For SOAP-API users, the right for login should not be given - this right is only necessary for the login into the frontend of the system.
To address the system with an interface, you must first create a role with the appropriate rights for the interface.
