I would like to have 3 nights minimum for direct bookings through my website, but 7 nights minimum for Airbnb bookings. Is it possible to make an API rule override for the specific channel? Thanks!
At present this is not planned, because it would potentially cause a great deal of confusion. What are you trying to accomplish here? You may be able to do something else to achieve the same effect, like raising your Airbnb rates.
I also would like to see this feature added. I would like to be able to allow 5 night stays on my direct booking website (with only sunday check-ins) so that summer guests who don't want the full week would be able to book Sunday through Friday morning, and then there would be a summer weekend available I can offer at a premium. This would be an awesome way to drive direct bookings IMO.
