Embed can be configured to use a different language using the locale property.
By default, this is set to en (English). Embed accepts a
ISO 639-1 Language Code (for example
en or fr) and an optional
ISO 3166 Country Code (for example
AU or GB). The country code allows a localized version of the
language to be provided based on a specific country, for example fr-CA would represent Canadian
French.
The locale can be set to any of the supported Locales. The
locale property falls back to English if a locale is not provided, is
incorrect or not supported.
Embed currently does not automatically detect the buyer’s locale. The locale
is always set to en when not provided.
