In case your site supports more than 1 languages, you will have the choice to push your preferred language during the integration process.
In more detail, in the script that displays the questionnaire in the Checkout stage you will have to add the variable:
`esat_supported_lang` is the preferred language you wish to be injected in every case, eg for the English language add _esatisf.push(['_lang', 'en']);
In the Browse stage, the questions will be displayed in your user's preferred (browser) language.
In the Checkout and Aftersales stage, the questionnaire's language is the one you will push through the variable mentioned above.
