Checkfront does not communicate/integrate with TripAdvisor or other third party review sites. In order to use them, you will need to create an account with them. After this you can "feed" them information via an delayed email-notification (http://www.checkfront.com/followup-email-reviews/)
In order to retrieve this information, you or your staff will need to log into that service. At present a login/view reviews via the Checkfront admin, is not supported.
