Add YouTube Channels
Adds channel IDs/URLs into the selected YouTube trigger set (matched by filter_options). You do not need to resend previously added channels. Behavior:
  • Creates a new trigger if none exists
  • Merges new channels into an existing trigger with matching filter_options if one exists
  • Creates a new YouTube trigger node when no existing trigger has matching filter_options
  • If a channel already exists on a different YouTube trigger node for this agent, it is moved to the selected trigger node
  • Deletes emptied YouTube trigger nodes after channel moves
  • Updates the webhook URL if trigger_callback_url is provided
  • Clears the webhook URL when trigger_callback_url is explicitly null

Parameters

Response

Duplicate Handling: If you add a channel that is already monitored on the selected trigger (same filter signature), it is ignored. If that channel exists on another trigger with a different filter signature, it is removed from the other trigger and moved to the selected one.Run Deduplication: At execution time, if multiple YouTube trigger nodes still match the same new video and target the same Video Input node, Mosaic starts one run for that target (not one run per trigger tile).
