📚 Document how the channel attribute on an Inbox Message controls relay to the originating platform (Airbnb, Booking.com, etc.) and how to derive the right value from the Conversation's default_channel. See the Inbox Messaging guide.
📚 Document that start_at and end_at on Create a new booking must be full datetimes whose time-of-day matches the rental's checkin_time / checkout_time. Date-only values get coerced to midnight and trip the "is within a used period" validation against adjacent bookings. The booking-creation example payloads now use full datetimes instead of START_AT / END_AT placeholders.
✨ Expose start_at_global and end_at_global on the Booking resource. These are the booking's check-in and check-out as true UTC instants (rental's timezone applied), suitable for absolute time-window comparisons. The existing start_at and end_at remain wall-clock values in the rental's local timezone.
🐞 Webhook deliveries now respect each application's per-account rental exposure (whitelist / blacklist) configuration, mirroring the visibility of GET /rentals. Rental-scoped events (booking_*, inquiry_*, photo_*, payment_*, review_*, etc.) are only delivered for rentals exposed to the receiving application. See Webhook subscriptions → Rental access scope.
✨ Document the difference between map and map_with_price_variation on the Mid Term Rate Map endpoint, and how the per-day price modifier is resolved from Applications Periods Rentals and the Application's default_price_increase.
✨ Document the application lock behavior when setting nightly_rates_managed_externally to true on a Rental: rates management is locked to the calling application, and a different application attempting to update the Nightly Rate Map will receive an explicit error.
