PX syncs in three modes: on connect, on demand, and via webhooks.

​
On connect

The first sync runs automatically as soon as PX validates your credentials. PX fetches:
  • Account metadata - the OAuth account ID and the admin user.
  • Your full property catalog.
  • A tax / fee / commission catalog (the way it is built depends on the PMS - see the relevant Connect page).
Reservations and per-booking financial data are pulled on demand and via webhooks from then on - they are not bulk-loaded at connect time.

​
On user action

These actions hit your PMS in real time: Each “on demand” call is rate-limit aware. If your PMS rejects with a 429, PX surfaces a banner with a countdown and the action’s button stays disabled until the cooldown ends.

​
Via webhooks

PX subscribes to PMS webhooks so changes propagate without you clicking sync:
  • Guesty - reservation created, reservation changed, listing changed.
  • OwnerRez - booking created, booking changed, payment received, refund issued.
Webhook health is shown on the Integration Status panel under Settings. A red light means PX did not register or failed verification - click Refresh there to retry. If you ever suspect data is stale, click Refresh on the relevant page. Most pages have a refresh button at the top.

​
Manual properties

You can also create properties manually from the Properties page (Add Manually). Manual properties have no PMS ID, so:
  • They are never overwritten by a sync.
  • They do not appear in audits - audits read from PMS reservations only.
  • They are useful for tracking off-platform inventory in PX without distorting your PMS data.

​
Switching PMSes

PX supports one active PMS per account. Switching requires:
  1. Settings -> remove the existing connection (Delete for Guesty, Disconnect for OwnerRez).
  2. Connect the new provider.
  3. Properties -> Sync from [new PMS].
Removing a connection also removes the properties synced from it, so you will not see two providers’ properties side by side. Your account-level configuration - business models, tax configuration, and audit history - stays in place, and step 3 repopulates the property list from the new PMS.
