n8n-nodes-buffer (Enhanced)

This is an enhanced fork of the official n8n community node for Buffer. It adds missing platform-specific required fields for Facebook and YouTube channels that were causing API errors.

Original repo: https://github.com/bufferapp/buffer-n8n
Enhancements by: Yorlandis Cuba

✨ Enhancements over original

• Facebook Post Type selector (Post / Story / Reel) — required by Buffer API
• YouTube required fields:
  • Video Title (required)
  • Category (required) — YouTube category IDs (e.g., 22 = People & Blogs, 27 = Education)
  • Privacy Status (optional) — Public / Private / Unlisted
  • Tags (optional) — comma-separated

These fields now appear automatically when you select a Facebook or YouTube channel, just like "Instagram Post Type" already did for Instagram.

Features

• Create Ideas - Save content ideas to your Buffer account
• Create Posts - Publish to social channels (X, Instagram, TikTok, YouTube, Facebook, LinkedIn, etc.)
• Flexible Scheduling - Publish immediately, add to queue, or schedule for a specific time
• Media Support - Attach images or videos to your posts
• Multi-Channel - Post to any connected Buffer channel
