Codes used in requests

Country and nationality: use ISO alpha-2 country/region codes, for example CN, US, GB. The country list API is the source for destination mapping.
Currency: APIs return the platform’s currency enumeration plus ISO code. Common values include 0/CNY, 1/HKD, 3/USD, 5/SGD, 7/JPY, 9/EUR, 22/GBP, 25/AED, 26/AUD, 110/TRY.
Bed and window types: keep the returned code as data. Bed codes can include 1000000 Queen, P000000 Double, A000000 Single, L000000 King, 2000000 Twin; window code 0 means no window and 2 means has window.

Update rule

Refresh local static data through the country/city, hotel increment, hotel detail and group-brand APIs. If a returned code is not yet mapped locally, retain the original code and use a safe fallback label rather than rejecting the response.
