To cancel a Flipkey Reservation on you should do it like the other sales channels: start the cancellation process by requesting it to the OTA in question (Flipkey in this case).

How to request cancelation to Flipkey?

It is worth mentioning that Flipkey is a channel that can work without Instant Booking, so if you have a bureaucratic process to fulfill before confirming a Reservation this might be the best way to go!

Although Flipkey does not have integration with Reservations it is important that you remove your Reservation only after you have confirmed the cancellation with the guest and Flipkey team, in order to avoid overbookings and other unforeseen issues.
