Gaggo Meyer 2 years ago Hi there, I have been trying for some hours now to get my head around the whole oAuth thing, but I don't seem to get it working. I want to retrieve thumbnails for private videos, using your advanced api. This is what I have right now: $vimeo = new phpVimeo($consumer_key, $consumer_secret, $access_token, $access_token_secret); $result = $vimeo->call('vimeo.videos.getThumbnailUrls', array('video_id ' => $video_id)); When I try it like this, I keep getting the error "Fatal error: Uncaught exception 'VimeoAPIException' with message 'Invalid signature' ". I'm absolutely positive that the keys and secrets are correct. Do I have to do more to make this thing work? Of course, it would be amazing to have an example where I just have to put in all my key data in and it works. thanks in advance!  Also, can I somehow make code look nice, like in other forums? I've tried "code" and "pre" tags, but they don't work... thanks!
