How long refresh Token( OAuth 2.0)  last in Khoros

Hi patils27 

Per https://developer.khoros.com/khoroscommunitydevdocs/reference/authrefreshtoken the refresh token does not expire. You can use that method to force a refresh if you like. You can also use https://developer.khoros.com/khoroscommunitydevdocs/reference/authinvalidatetoken to invalidate a refresh token.
