I've always been confused about these two properties in regards to a VCL application. What is the intent of these? Should they be pointing to a web url and perhaps a web app running on a specific port? Should there be some sort of response when the url is called?
The callback url and port are part of the oAuth 2 authentication process. This is the location where the service will provide the authentication token to the TMS FNC Cloud Pack component after authorization. The component needs an authentication token to be able to retrieve an access token. This is usually a localhost url which is monitored by the TMS FNC Cloud Pack component.
