# This sample sets a custom banner to user's channel by:
#
# 1. Uploading a banner image with "youtube.channelBanners.insert" method via resumable upload
# 2. Getting user's channel object with "youtube.channels.list" method and "mine" parameter
# 3. Updating channel's banner external URL with "youtube.channels.update" method
