Multi-Language Support

Introducing more localized video call UI for German, Finnish, Portuguese and more! is happy to announce support for even more languages in your API calls! We now support Dutch, English, Finnish, French, German, and Portuguese. You can set the language preference for your calls using either the front-end or REST APIs.

### Using the REST API

You can set the language preference for [your domain]( (used for all room), [a single room](, or [using a token](

   -- CODE language-bash --
   # Domain Level Setting
   curl -H "Content-Type: application/json" -H "Authorization: Bearer [[API KEY]]" \
   -XPOST -d '{"properties":{"lang":"de"}}'

   # Room Setting
   curl -H "Content-Type: application/json" -H "Authorization: Bearer [[API KEY]]" \
   -XPOST -d '{"properties":{"lang":"en"}}'[[ROOM NAME]]

   # Token Specified
   curl -H "Content-Type: application/json" -H "Authorization: Bearer [[API KEY]]" \
   -XPOST -d '{"properties":{"room_name": [[ROOM NAME]], "lang":"fi"}}' \

### Using the front-end API

In the front end, you can set the language for the UI using either the `lang` property in the [factory methods]( or by calling [`setDailyLang()`]( on your DailyIframe.

   -- CODE language-markup --
   callFrame = window.DailyIframe.createFrame({
     lang: 'fr'

   // OR

Note: `setDailyLang()` must be called after the call to `join()`.

### Using a user's browser settings

Instead of specifying a single language, you can also use the value `user` to let the user's browser settings determine the language. If the user's settings do not match one of our supported languages, they will default to English. **Note:** The `user` setting is only available via the REST APIs.

### Which setting will the UI use?

The language is set according to the following priority:

1. `setDailyLang()`
2. token
3. DailyIframe property
4. room
5. domain
