YouTube Post

Publish content to YouTube. Upload a video (including AI-generated ones) to your channel, post a top-level comment on a video, or reply to an existing comment.

This block uses OAuth (the YouTube Google connection) and is distinct from the read-only YouTube block, which uses an API key for search and metadata.

Usage Instructions

Add the YouTube Post block to your workflow canvas, connect a YouTube account, and pick an operation:

• Upload Video — provide a title, optional description, a video source (a file reference such as a Video Generator's videoUrl, or a direct URL), and a privacy status. The block initiates a resumable upload, downloads the source bytes, and streams them to YouTube. Uploads default to private so nothing goes public by accident.
• Post Comment — comment on a video by videoId.
• Reply to Comment — reply to a comment by its parentId.

Authorization

Requires the youtube.upload and youtube.force-ssl scopes. These are Google restricted scopes: production use by non-test users requires Google OAuth app verification. During development, add the channel's Google account as a test user on the OAuth consent screen and enable the YouTube Data API v3 on the OAuth client's Google Cloud project.
