The in-app referral widget can be displayed in several languages. By default the widget is shown in English. You can select a different language per user by passing the lang option when you load the widget.

Setting the Language

Pass the lang option to gr("loadReferralWidget", ...) with one of the supported codes:
Javascript
window.gr("loadReferralWidget", {
  product_id: PRODUCT_ID,
  auth_token: authToken,
  lang: "de", // Display the widget in German
  user_details: {
    email: "john@example.com",
    first_name: "John",
    last_name: "Doe",
    company_id: "1as2-3df4-5fg6-7hj8",
    company_name: "Acme",
  },
});
Set lang to the language your user has selected in your application. If you load the widget again with a different lang, the new language takes effect the next time the widget is shown.

​
How It Works

  • English is the default. If you omit lang, or pass a value that is not supported, the widget falls back to English.
  • Region variants are accepted. Values such as fr-CA or pt-BR are matched to their base language (fr, pt). If the base language is not supported, the widget falls back to English.
  • English is always available instantly. English ships with the widget. The other languages are loaded on demand the first time they are needed, so there is no extra cost for users on the default language.
  • Safe fallback. If a translation cannot be loaded for any reason, the widget continues to work and shows English instead.

​
What Gets Translated

The lang option translates the widget’s own interface: tab names, buttons, labels, instructions, and status messages. Content that comes from your Reditus configuration is shown as you entered it, and is not translated automatically. This includes:
  • Your referral program name.
  • Custom reward descriptions.
  • Your Terms and Conditions.
  • Monetary amounts and currencies.
If you need this configured content in another language, set it in the language you want your users to see in your Reditus referral program settings.
