Internationalization

The SDK supports 80+ languages for UI text and error messages.

Setting the Language

Pass the lang property inside the config object when configuring <incode-flow>:

flow.config = {
  token: session.token,
  lang: 'es', // Spanish
};

Supported Languages

The following language codes are supported. The SDK loads translations from CDN at runtime.

Additional codes like af-ZA, am, az, bs, ceb, da-DK, et, fa-IR, fi-FI, hmn, ht, jv, ka, kk, km, ky, lo, lt, lv, mk, mn, my, nb-NO, ne, so, sv-SE, ur, uz and more are also supported.

How It Works

• The lang property sets the UI language for all SDK components within the flow
• Translations are loaded from Incode's CDN at runtime
• Error messages and instructions are automatically translated
• The language is also sent to the backend for server-side localization

Browser Language Detection

To use the browser's preferred language:

const browserLang = navigator.language.split('-')[0]; // 'en', 'es', etc.

flow.config = {
  token: session.token,
  lang: browserLang,
};

RTL Support

Right-to-left languages (Arabic, Hebrew, Farsi) are supported. The SDK automatically adjusts layout direction based on the language.
