I am using the Youtube data API and I needed to know if there is any way of finding that the youtube channel is a Verified one.
RE: mpgn's solution, note that there's a distinction between whether the G+ account is Verified and whether one or more of the accounts YouTube channels are Verified. It's possible for an account to have more than one channel, and each of those channels are verified independently, and for channels to be unverified even though the associated G+ account is verified.
As @Paul Blakely suggests, the current best way to do this is to check the status.longUploadStatus flag, per https://developers.google.com/youtube/v3/docs/channels
