If you see HomeRunner listed in the Guesty Marketplace, you do not need to switch to it. There is no separate connection to switch to.
How the connection works. The HomeRunner connection runs on the Open API and Booking Engine API credentials you already set up in Guesty. The marketplace entry is a listing of the integration, not a different connection type.
Google Vacation Rentals. Google Vacation Rentals reads your listings from Guesty’s own Google feed, so nothing on the HomeRunner side changes what Google receives. If your listings are not appearing on Google Vacation Rentals, contact Guesty support.
