I ran into the same issue.

You should append access token to the thumbnailLink URL, which will authorize your GET request for it.

So something like:

var thumbLink = driveEntry["thumbnailLink"] + "&access_token=" + YOURTOKEN;

Cheers.

To get the thumbnail of a file stored on Google Drive you have to send a GET request to the file endpoint and then check its thumbnailLink property:

https://developers.google.com/drive/v2/reference/files/get

Regardless of the format of the thumbnail URL, as long as you use the value returned in the file metadata you should be fine.

Please take into account that thumbnail URLs expire after a certain time.
