Connect your Prop-Sync calendar to Trip Advisor using Prop-Sync's iCal interface.
Although not quite real-time, have peace of mind your availability is shared to Trip Advisor.
Currently this is just one-way, so changes made on Trip Advisor will not update on Prop-Sync or to other connected calendars via Prop-Sync.
The calendar URL can be obtained from Prop-Sync Admin. Click on Settings, then click on the unit you wish to sync the calendar with and in the unit page you can add "Prop iCal" which will provide you with the URL to apply on Trip Advisor.

Please note that this is an integration that Prop-Sync have not tested however we have on good authority by customers using the connection that it all works fine. We will endeavour to enhance our connection with Trip Advisor and add in quality control checks in due course.
NB: iCal based integrations are not real-time and carry delay in availability updates from showing.
