I am trying to create a new APIClient object. When i try to generate the token silently most of the time it cannot create the access token using the Refresh token. Any specific reason why this happens? Due to this i am getting the sign in popup all the time

I am trying to retrieve data from a windows service application using Sage 200 API. When authenticating there is a popup showing up to sign in. We cannot have this popup in a windows service application since it has no user interaction. Is there a workaround for this?
