There are three approaches to try.
Update
From the Guests page, click the Update link located above the Reservation dropdown. This refreshes any last-minute updates to Cloudbeds reservations. Then verify by searching for the record that you noticed was missing.
Missing reservation
The second approach, if it is just a single reservation missing, is to use the Missing Reservation tool to import. You'll be prompted for the Cloudbeds reservation ID that is missing. When you enter that, it will retrieve the record from Cloudbeds.
Re-connect Cloudbeds (OWNER/ADMIN ONLY)
If you have multiple reservations on your PMS that are not showing up on Planniac, there is a connection problem, and you should follow these directions:
CAUTION: This should only be done by the primary account owner!
Take these steps:
Log to Planniac in as the account owner or full Admin on your Cloudbeds account
On Planniac, click Settings > Re-connect Cloudbeds
Log in to Cloudbeds as prompted. If you are already logged in, it may not require a new login.
You should be automatically returned to the Planniac login screen.
Go to the Guests page, and using the Reservations dropdown list, verify that the missing reservations have been imported.
What to do if a reservation is there, but is not showing the correct dates
If a reservation has been modified during a disconnected period (like changed or extended dates), just change the status in Cloudbeds from “Confirmed” to “Pending” or any other status and then change it back again. That will send the correct data back to Planniac.
Or, if you know any that have been modified, you can select the guest from Planniac and then click “Update” which will refresh the reservation from your PMS with the changes.
