This is related to rewritting of new GSX APIs to REST methods Phase 1 which includes Authentication process.Currently we have to visit https://gsx2-uat.apple.com/gsx/api/login link in order to obtain API token which we will be using in further GSX APIs as a process of Authentication.Do we have any GSX API through which we can fetch API token instead of visiting above said URL for fetching API token? So that we can integrate that API and thereby use the same API token in further GSX APIs.
