🎯 What This Workflow Does

This template manages the end-to-end lifecycle of a Reel, from submission to final community notification:

📝 Submission & Notion Integration

n8n Form Trigger:** Public form to submit a Notion Page ID and select caption tone (Hype, Minimal, Storytelling). Data Extraction:** Pulls video file, cover image, and metadata (Title, Description, Tags) from Notion. Validation:** Ensures content is not already published or failed.

🤖 AI Creative & Media Hosting

Claude AI Captions:** Uses Anthropic Claude-Haiku to generate brand-safe, tone-specific captions under 2,200 characters. Mandatory CDN Hosting:** Uses UploadToURL to convert Notion files into public HTTPS URLs required by Instagram.

📧 The Approval Gate

Email Approval Step:** Sends preview email with: AI-generated caption
Video preview link
Approve / Reject buttons
