VRBO bookings made via OR's api not seen in VRBO Dashboard.

VRBO bookings made via OR's api channel do not show up in my VRBO Dashboard. I have about 4 already and do not see any record of them on my VRBO dashboard. Should I be concerned?

No, that's normal - when you're using the Vrbo API, your Vrbo dashboard calendar should be ignored.
