Automate YouTube-to-X Posts with n8n Schedule Trigger

Automatically promote your newest YouTube videos on X (Twitter)—every 30 minutes—using n8n

This n8n automation workflow checks your YouTube channel for new uploads and automatically generates a polished promotional post with OpenAI, then publishes it to your X account—so your audience stays updated without manual effort.

What this workflow does

• Runs on a schedule: the Schedule Trigger fires every 30 minutes to look for newly published YouTube videos.
• Detects new content: the workflow fetches recent videos from a specified YouTube channel using your Channel ID.
• Generates an engaging message: when a new video is found, OpenAI ChatGPT (GPT-3.5 turbo) creates an X-ready promotional message.
• Posts to X: the workflow publishes the generated message to Twitter/X so your latest content goes live promptly.

Use cases

• Content creators who want consistent cross-platform promotion without copy/pasting captions.
• Marketing teams that need reliable “new video → social post” updates on a fixed cadence.
• SaaS operators and operators managing multiple channels and ensuring frequent engagement with minimal hands-on work.
• Automation engineers building repeatable workflows: YouTube feed → OpenAI text → Twitter post.
