Answer 1

I was able to pass along a header using this code below:

    jQuery.ajax({
        type: 'DELETE',
        // must set api key
        url: 'https://www.googleapis.com/youtube/v3/videos?id='+ thisUniqueID +'&key=api_key_here',
beforeSend: function(xhr){xhr.setRequestHeader('Authorization', 'Bearer access_token_here');},
        success: function() {
        alert('your video has been deleted');
        },
        error: function() {
        alert('error processing your request');
        }
    });
