Sets prices, minimum nights, check-in and check-out blocks, and blocked dates on a listing's calendar. Send one entry per date, with only the fields you want to change.

blocked: true blocks the date, the same as blocking it on the Host Tools calendar, so it reaches the listing's channels the same way. blocked: false removes the block. It can't open a date held by a reservation or a calendar rule. Blocking works on any listing, whatever its price source.

price, minNights, blockCheckin and blockCheckout only apply to listings whose price source is API (see priceSource on Set Listing). minNights, blockCheckin and blockCheckout also need a price from this endpoint on the same date. On other listings, Host Tools stores these values but doesn't use them.

Host Tools only updates dates already on the calendar, about two years ahead, and ignores later ones. Changes reach the channels in the background. Get Calendar shows a new block as blocked: true once Host Tools has recalculated the calendar.
