Localization

Learn more about all possible languages and formats.

Unzer UI components support localization with the locale parameter. You can set it when initializing the Unzer object on the client side. The default value is auto, which uses the client’s browser language.

// Creating an unzer instance with your public key
var unzerInstance = new unzer('s-pub-xxxxxxxxxx', {locale: 'de-DE'});

curl --location --request GET 'https://api.unzer.com/v1/customers/s-cst-65b81db7b68f' --header 'Accept-Language: de-DE' -u 's-priv-xxxxxxxxxx'

$unzer = new UnzerSDK\Unzer('s-priv-xxxxxxxxxx', 'de-DE');

Unzer unzer = new Unzer("s-priv-xxxxxxxxxx", Locale.GERMANY);
