Switch language via API

[evaluation]

I want to integrate this forum into a self-written Java web-application. When the user changes the language in the web-app and switches to the forum the user should see the forum in the same language as in the web-app. Is this possible via an API call? If not how can this be achieved?

Thx,
Sebastian
