Hi zachtines , I'd suggest checking whether the account you're using to login has Auto Sign-in enabled. If so, the refresh token will not be returned. This is what the "Note" on this page is referring to: https://developer.khoros.com/khoroscommunitydevdocs/reference/request-auth-token-oauth
One thing that's not clear from the documentation is that disabling Auto Sign-in via the admin will not resolve this issue for existing accounts, since the preference will have already been stored in the existing account. You would need to login to the UI with the account and disable Auto Sign-in in the individual account's preferences.
I hope this helps!
