Promote New YouTube Videos on X

Find the latest recent video from a YouTube channel and write a short X post.

Setup

Connect YouTube in Find the latest video and set its channel ID. Configure the AI model and connect Post on X to an account allowed to post. In n8n select YouTube, OpenAI and X credentials and set the channel ID. Activate one format.

Behavior

Every 30 minutes, search the channel for its latest video published in the preceding 30 minutes. If found, an AI model writes an X post including the video link. No video means no post. The latest-only search can miss multiple uploads; indexing delays, downtime and schedule boundaries can miss videos. There is no persistent deduplication or workflow retry. n8n OAuth2 can refresh the X token and resend once after HTTP 401. Review model output and check X before retrying a failed or uncertain post. YouTube search uses API quota. Open Flow runs at UTC half-hour boundaries; n8n’s interval is phased from activation.

Changes to the source

Replace the personal channel and credentials with setup. Open Flow uses the YouTube Connection Proxy for channel-only search, as the Search Action requires a query term.
Sort results by publication date in both formats; the source omitted the order and the API defaults to relevance.
Check the generated post includes the video URL and fits 140 characters before posting. Open Flow uses an AI Agent; n8n retains the source model node.
