Calendar channels (like AirBnB & VRBO) have limited functionality with channel managers (like MyAllocator) and therefore Odysys.
Calendar channels do not notify MyAllocator of cancellations. Because of this, cancelled reservations from calendar channels will need to be executed manually in Odysys. Click here to learn how to change and cancel reservations in Odysys.
The only information that can be sent from Odysys to your calendar channels at this time is availability. Rates and cancellations must be managed at the channel itself.
For a full walkthrough of how to handle OTA and calendar channel cancellations in MyAllocator, read this article.
