I have few doubts on the refresh token and extending expiry time for the access token.
1. I am not able to get refresh_token as part of the token response. Is it possible to get a refresh_token for System scope.
2. Is it possible to obtain a single access token that covers for all system scopes (eg: Patient.read, Patient.write, Encounter.read and so on..)
3. Is it possible to increase the expires_in time for access_token in any way, so it lasts for longer periods of time. I did read about obtaining refresh_token using offline_access but unable get the same as well for System scope.
Need help on the above topics.
Thanks in advance,
