What to Expect After Connecting

  • Guest messages appear in your Trellis inbox so your team can respond from one place

After the initial sync, ongoing changes typically appear in Trellis within a few minutes.

​
Calendar blocking and unblocking

You can block and unblock dates on your Guesty calendar directly from Trellis — including through the AI agent. This is useful for owner stays, maintenance windows, or any period you need to take a listing off the market. When you block dates, you can include a reason and a note:
  • Reason — choose from Guesty’s standard categories (for example, “Owner block” or “Maintenance”)
  • Note — add free-text details explaining why the dates are blocked (for example, “Kitchen renovation through the 15th”)
If your block reason doesn’t match one of Guesty’s predefined categories, Trellis automatically saves your text as a note so it’s always preserved in Guesty’s calendar.
To unblock dates, ask the AI agent or use the calendar in Trellis to remove an existing block. The change syncs back to Guesty immediately.

​
Good to Know

  • Custom fields currently sync from Guesty to Trellis (one way). Editing custom fields in Trellis won’t push changes back to Guesty yet.
  • All reservation notes from Guesty are imported as internal notes — they’re visible to your team but not to guests.
  • If you add a new property in Guesty, it will automatically appear in Trellis during the next sync cycle.
Make sure your Guesty API key has the correct permissions. If properties or reservations aren’t syncing, double-check your API key settings in the Guesty Marketplace.
