Upload & Categorize Files with Supabase Storage and Secure URL Generation
# Supabase Storage File Upload Workflow
*works with self-hosted Supabase*
## How it works
- Accepts file data (MIME type, filename, base64 content) from other workflows
- Automatically routes files to appropriate storage buckets based on file type (images, audio, video, documents)
- Uploads files to Supabase Storage using the REST API
- Generates secure signed URLs for file access with 30-day expiration
- Returns structured success/error responses for downstream processing
## Set up steps
- Configure Supabase API credentials in n8n
- Create storage buckets in your Supabase project (image-files, audio-files, video-files, document-files) (or choose your own structuring system)
- Replace URL paths with your own
- Test the workflow using the included form trigger
- Remove test form and integrate with your main workflows
