There can be several reasons why some YouTube channels are not showing up when using the YouTube API. Here are a few common causes:

  1. Channel Required
    • YouTube posting requires your YouTube account to have at least one Channel and be an owner on the Channel. To create a YouTube Channel, click on you profile in the YouTube Dashboard and choose “Create a Channel”. You may also use this direct link to create a YouTube Channel: http://m.youtube.com/create_channel
  2. Owner or Admin of the Channel
    • The Google account logged in as must be the owner or admin of the Channel for it to be presented.
  3. Channel Privacy Settings
    • If a channel owner has set their channel privacy to “Private” or “Unlisted,” their channel and its content will not be accessible through the API.
    • Private channels are only visible to the channel owner and authorized users, while unlisted channels can only be accessed with the direct channel URL.
  4. Age or Region Restrictions
    • If a channel has age-restricted content or is restricted in certain regions.
    • Age-restricted channels require users to be signed in and meet the age requirements to view the content.
  5. Deleted or Suspended Channels
    • If a channel has been deleted by the owner or suspended by YouTube for violating terms of service, it will no longer be accessible through the API.
    • Deleted channels are permanently removed, while suspended channels may become accessible again if the suspension is lifted.
