Promote your latest YouTube videos on X without manual work. The flow writes a short post, keeps it under the limit, and logs each post in Google Sheets. Ideal for creators and marketing teams that want steady social updates.

Every two hours a scheduler checks your YouTube channel for new uploads from the last 20 hours. New items pass a duplicate filter so the same video never posts twice. OpenAI drafts the post and, if needed, uses Wikipedia and Calculator tools. A length check loop rewrites the copy to about 220 characters, then the text is stored in Google Sheets and published to X with the sheet entry updated.

Connect YouTube, OpenAI, X, and Google Sheets in n8n, then paste your Channel ID and select your sheet. Expect a clear time win by shrinking a 30 minute task to a few minutes while keeping a clean audit trail. Great for channels that release often, social teams that plan daily content, and solo creators who want hands off promotion.

• Post to X publishes the approved copy and then updates the sheet record
• Optional Slack, Discord and Gmail nodes ready for team notifications

• Reduce manual social posting from 30 minutes to 3 minutes per video
• Eliminate repeat posts for the same video with cross run dedupe
• Keep every post within 240 characters to avoid truncation

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You will need accounts with YouTube, OpenAI, X, Google Sheets, Slack, Discord and Gmail. See the Tools Required section above for links to create accounts with these services.
3. Connect YouTube: double click the YouTube node named Fetch Latest Videos, open the Credential to connect with menu, click Create new credential, then follow the on screen steps to sign in. Use a clear name like YouTube OAuth Main.
4. Set your Channel ID in the YouTube node. Paste your channel ID into the Channel ID field and keep the time filter so only recent videos pass.
5. Connect OpenAI: open the nodes Generate X Post and Rewrite X Post to 220 Characters, create a new OpenAI API Key credential, and paste your key from your OpenAI account. Name it OpenAI API Main.
6. Connect X: open the Post to X node, create a new X OAuth2 credential, and complete the sign in. Confirm the account has permission to post.
7. Connect Google Sheets: open GS - Add Tweet and GS - Update Tweet, create a Google Sheets OAuth credential, choose your spreadsheet and the Sheet1 tab. Confirm useAppend and appendOrUpdate are set as shown.
8. Optional notifications: open the Slack and Discord nodes. For Slack incoming webhook and Discord webhook credentials, paste your webhook URLs and save. For Gmail, create a Gmail OAuth2 credential if you plan to email alerts.
9. Open the Schedule Trigger and confirm it runs every two hours with a random minute. Adjust the interval if you want a different cadence.
10. Check the Remove Duplicates node. Ensure the dedupe value is set to the video ID and scope is workflow so earlier posts are remembered.
11. Review the Verify character limit constraints and Rewrite nodes. Keep the target near 220 characters to leave room for links. Adjust the prompt if your brand voice needs changes.
12. Map the Google Sheets columns: confirm xid, date, time and post fields are filled from the generated message, and that Update writes back after posting.
13. Run a test with the Manual Trigger. If nothing posts, make sure a new video exists in the last 20 hours and the channel ID is correct. If posts are too long, lower the target length.
14. If Slack or Discord messages show missing fields, update the message template to reference data from GS - Add Tweet or the Post to X node. Save and retest.
