Hosted Page Language Support
A hosted page can appear in many foreign languages.
You can set the default language of a hosted page. The end user (customer) can select any other supported language.
The language (or merchant_language) field determines the default language of a hosted page. The field type is string. Use lower-case letters for the value.
If no value is specified, the language of the user's browser is used.
If the language of the user's browser cannot be determined, the default language is English.
For a list of supported languages, see List Supported Languages.
