Vimeo API将隐私设置为禁用

I'm using the new Vimeo API and I've successfully changed the title of a video but I also need to change the privacy settings. I thought I'd simply be able to do:

    $lib->request($uri, array('name' => $post_title, 'privacy' => 'disable'), 'PATCH');

But this doesn't work. Any ideas?

Thanks, Helen

The docs are a little out of date. The field should be "privacy.view"
