🔧 n8n Workflow Integration

VideoGenius AI leverages n8n as the core automation engine that orchestrates the entire video creation pipeline. The workflow handles AI service coordination, media processing, and YouTube publishing in a visual, node-based environment.

📋 Workflow Import

The complete video generation workflow is defined in complete_video_generator.json. This workflow must be imported into your n8n instance to enable automated video creation.

To import the workflow:

1. Access n8n Dashboard

   http://localhost:5678
   

2. Import Workflow

   • Click "Import from File"
   • Select workflows/complete_video_generator.json
   • The workflow will automatically connect to Laravel backend

3. Workflow Configuration

   # No API credentials needed in n8n!
   # Laravel handles all external API integrations:
   # - OpenAI/GEMINI API (configured in Laravel .env)
   # - Pexels API (configured in Laravel .env)
   # - Google Cloud TTS (configured in Laravel .env)
   # - YouTube API (OAuth handled by Laravel)
   # 
   # n8n only needs Laravel webhook endpoints
