Reepay Checkout supports a number of languages that can be set for a session by using the locale parameter or defining it for the Checkout configuration used. The locale represents a language and specific country or region (<language>_<country>). The locale is used to determine language, but also to determine how to do formatting og e.g. amount and currency. Reepay supports at least the locales below. Other country codes may be used for formatting, but only the listed languages are supported. If no locale parameter is provided, it defaults to configuration locale or account locale.
