1) From Response: I extracted AccessToken Value and used it; But I need to add AuthTokenType which is Bearer in front of the value ?? how can i add alphabet Bearer in front of extracted token value and pass it.

2) Access Token expires in 15 minuted with new token type Refresh Token - how do i make my scripts understand that when access token expires USE refresh token

Have anyone dealt with this please?
