Currency for displayed prices.
Property's own currency is the first choice and matches Booking's own picker: prices come back in whatever the property quotes in — MYR in Kuala Lumpur, THB in Bangkok — with no conversion. Every row states its own currency, so you always know which you got.
Booking cannot be asked for that, though: left to the property, the room-list request comes back with no rooms at all — on every property, not a few (measured 2026-10-29 on five properties in four markets). So this Actor reads each property's own code first and then asks for it explicitly, which is what the setting promises. Where a property's code cannot be read, its rates are skipped rather than mispriced and the run says so in its log, naming this input — pick an explicit code for that one.
Otherwise pick one of 147 currencies. That is every ISO-4217 code Booking honours on this surface, established by requesting a property once per code and reading back the currency it priced in, with bogus codes as the control.
The nine it refuses are ERN, FKP, GIP, KPW, SHP, SLE, TMT, VED and ZWG. They are refused outright rather than falling back silently, so you cannot ask for one by accident.
Booking's app only offers 49 of the 147 in its own menu, and its exchange-rate table lists 188 — including pre-euro currencies and gold. The 147 here is the set measured to actually price a room.
Every price in a row follows this setting, including the cancellation ladder and the prepayment schedule. One documented exception: details.damageDeposit.amount stays in the property's own currency, because a deposit is collected at the desk in local money — its currency says so.
