@bgweb I don’t think there is any integration. They’re just videos, restricted to playback on a specific domain (laracasts.com).
EDIT: Literally just an iframe with the video URL. The URL isn’t hashed nor contains a signature with an expiration.
But try and open that iframe URL in a new tab and you’ll just get an error saying the video can’t be played because of privacy settings: https://player.vimeo.com/video/523936153?color=00b1b3&autoplay=1&app_id=122963
