🎬 YouTube New Video → Auto-Post Link to Slack

This workflow automatically checks your YouTube channel’s RSS feed every 30 minutes and posts a message to Slack when a new video is published. It includes the title, description snippet, publish date, and a direct “Watch Now” button.

⚙️ How It Works

1. Check Every 30 Minutes

   • A Cron node runs on a 30-minute interval.
   • Keeps monitoring the channel RSS feed for updates.

2. Fetch YouTube RSS

   • The HTTP Request node retrieves the channel’s RSS feed.
   • Uses the format:

     https://www.youtube.com/feeds/videos.xml?channel_id=YOUR_CHANNEL_ID
     

3. Parse RSS & Check for New Video

   • A Code node extracts video info:
     • Title
     • Link
     • Description
     • Published date
   • Sorts by most recent publish date.
   • Ensures only new videos within last 2 hours are processed (avoids duplicate posts).

4. Format Slack Message

   • Builds a rich Slack message with:
     • Video title
     • Description preview
     • Published date
     • Button: “🎥 Watch Now”

5. Post to Slack

   • Sends the formatted message to your chosen Slack channel (default: #general).
   • Includes custom username/icon for branding.

🛠️ Setup Steps

1. Get YouTube Channel RSS

• Go to your channel page → View Page Source.
• Find: channel/UCxxxxxxxxxx (your channel ID).
• Construct RSS feed:
  https://www.youtube.com/feeds/videos.xml?channel_id=YOUR_CHANNEL_ID
• Replace YOUR_CHANNEL_ID_HERE in the HTTP Request node.

2. Connect Slack

• Create a Slack app at api.slack.com.
• Add OAuth scopes: chat:write, channels:read.
• Install to your workspace.
• In n8n, connect your Slack OAuth credentials.

3. Adjust Timing (Optional)

• Default = runs every 30 minutes.
• Modify the Cron node if you want faster or slower checks.
