If a listing has been set as 'Instant Book' then once a successful payment is made and the Booking Status is changed to 'Confirmed' then calendars will be automatically blocked.
If a listing is not set to Instant Book then the status of the booking will be in "Request" (and therefore no blocking will be in place) until the property manager has clicked ‘Confirm Booking’ in the email that is automatically sent to them when a booking status moves into ‘Request’.
When a Property Manager or Host has blocked out dates via the Plum Host dashboard (extranet) calendar.

When a Property Manager or Host has synced their ICAL through the Plum Host dashboard (extranet)
When a Property Management System or Channel Manager blocks out dates via an API request

Endpoints to set other Availability restrictions (Minimum Nights, Restricted Booking Windows, Change Over Days etc) are available here
