When you connect Guesty, you can limit which listings appear on your website either by restricting the Booking Engine API key to specific listings or by using a tag.
Recommended approach. Give the Booking Engine API key access to all listings you may ever want on the website, then apply a tag to each listing you want to appear. HomeRunner filters by that tag.
Why not restrict the key. If the key covers only a subset of listings, every new listing requires editing the key, which is easy to forget. A listing outside the key cannot sync no matter how it is tagged. Managing visibility through a tag is simpler to maintain over time.
