ComfyUI Google Drive Upload Node

A custom ComfyUI node that uploads images directly to Google Drive. Designed for serverless environments like ComfyDeploy.

Features

• Upload images in PNG, JPEG, or WEBP format
• Configurable folder destination per execution
• Optional timestamp in filenames
• Multiple authentication methods for flexibility
• Returns upload status and file URL

Installation

For ComfyDeploy

1. Add this repository as a custom node in your ComfyDeploy workflow
2. The dependencies will be installed automatically from requirements.txt

For Local ComfyUI

cd ComfyUI/custom_nodes
git clone https://github.com/theclueless-ai/comfyui-google-drive-upload
cd comfyui-google-drive-upload
pip install -r requirements.txt

Google Cloud Setup

1. Create a Service Account

1. Go to Google Cloud Console
2. Create a new project (or select existing)
3. Enable the Google Drive API:
   • Navigate to "APIs & Services" → "Library"
   • Search for "Google Drive API" and enable it
4. Create Service Account:
   • Go to "IAM & Admin" → "Service Accounts"
   • Click "Create Service Account"
   • Name it (e.g., comfyui-drive-uploader)
   • Click "Create and Continue" → "Done"
5. Generate Key:
   • Click on your new Service Account
   • Go to "Keys" tab
   • "Add Key" → "Create new key" → "JSON"
   • Save the downloaded JSON file securely

2. Share Your Drive Folder

1. Open Google Drive
2. Right-click your target folder → "Share"
3. Paste the Service Account email (found in the JSON as client_email)
   • It looks like: name@project-id.iam.gserviceaccount.com
4. Give "Editor" permissions

3. Get Your Folder ID

The folder ID is in the URL when you open the folder:

https://drive.google.com/drive/folders/1pnceWEOPxlMeKmuDWMxmMHzVILGjGeZI
                                        └──────────────────────────────────┘
                                                    This is the folder_id

Authentication Methods

The node supports multiple ways to provide credentials (in priority order):

Option 1: Direct Input (Easiest for Testing)

Paste the entire Service Account JSON directly into the service_account_json input field.

Option 2: Base64 Environment Variable (Recommended for ComfyDeploy)

# Encode your JSON file
cat service-account.json | base64

# Set as environment variable in ComfyDeploy
GOOGLE_SERVICE_ACCOUNT_BASE64=<base64-encoded-string>

Option 3: JSON Environment Variable

# Set the raw JSON as env var (escape quotes properly)
GOOGLE_SERVICE_ACCOUNT_JSON='{"type":"service_account",...}'

Option 4: File Path (Local installations)

GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json

Example Workflow

[Your Image Generation] → [GoogleDriveUpload]
                              ├── folder_id: "1pnceWEOPxlMeKmuDWMxmMHzVILGjGeZI"
                              ├── filename_prefix: "ai_generated"
                              ├── image_format: "PNG"
                              └── add_timestamp: true

Troubleshooting

"No Google credentials found"

• Verify your Service Account JSON is valid
• Check environment variables are set correctly
• For Base64, ensure no extra whitespace

"Access denied" or "File not found"

• Confirm the folder is shared with the Service Account email
• Verify the Service Account has "Editor" permissions
• Double-check the folder_id is correct (no URL parameters)

"API not enabled"

• Enable Google Drive API in your Google Cloud project
