How to set the chatbox language dynamically?

By default, Crisp auto sets the chatbox language based on the visitor web browser language. You can even force a global language in the website settings. If, however, your website is localized in multiple languages, and you'd like to force chatbox language based on the current language of your website, you may want to use the Crisp JavaScript API.

How to force locale

This configuration can be forced by adding a locale parameter to the special variable CRISP_RUNTIME_CONFIG, as follows (for French):

  locale : "fr"

The locale code follows the ISO 639-1 format.

Add this JavaScript code right in the Crisp chatbox HTML code in the <script></script> tag.

Any trouble?

If you cannot get the locale to be forced this way, check that chatbox locales are not restricted. Go to your website configuration:

  • Go to:
  • Go to your settings: click on the settings icon
  • Click on "Websites"
  • Select your website in the list
  • Look for the locales configuration box and select "Detect from visitor country"
