Localization

The text displayed in the Checkout page can be rendered in multiple languages.

It is possible to allow the customer to select a language on the page and to set a preferred language to be used by default.

It is also possible to only display a single language and remove the option for the cardholder to select a different language.

• i18n - The i18n field in the Create checkout API request is used to configure the localization settings.

• default_language - The default language is used for displaying the page. Any customer language choice would override this option.

• fallback_language - The fallback language is used when the default_language is invalid. Any customer language choice will override this option.

• show_language_options - Indicates whether a language selection option should be shown to the customer on the Checkout page or not.

Language settings

Setting a language and not allowing the user to change the language:

{
  ...
  "i18n":{
    "default_language": "en",
    "fallback_language": "en"
    "show_language_options": false,
  }
  ...
}

Setting a language and allowing the user to change the language:

{
  ...
  "i18n":{
    "default_language": "en",
    "show_language_options": true,
  }
  ...
}

As an example, the French language with an option to change the language and fallback to English would be configured like this:

{
  ...
  "i18n":{
    "default_language": "fr",
    "fallback_language":"en"
    "show_language_options": true,
  }
  ...
}
