  • auditDetails (object) The auditDetails object encapsulates channel data that a multichannel network (MCN) would evaluate while determining whether to accept or reject a particular channel. Note that any API request that retrieves this resource part must provide an authorization token that contains the https://www.googleapis.com/auth/youtubepartner-channel-audit scope. In addition, any token that uses that scope must be revoked when the MCN decides to accept or reject the channel or within two weeks of the date that the token was issued.
  • overallGoodStanding (boolean) This field indicates whether there are any issues with the channel.
