🚀 Google Drive Quick Setup Guide

If you run into invalid_client errors, use the Service Account approach (simpler and more reliable).

⭐ Recommended: Service Account (≈5 minutes)

Step 1: Create a Service Account (≈2 minutes)

1. Visit Google Cloud Console
2. Create a new project or select an existing one
3. Enable the Google Drive API:
   • Left menu → “APIs & Services” → “Library”
   • Search “Google Drive API” → click “Enable”
4. Create the Service Account:
   • Left menu → “IAM & Admin” → “Service Accounts”
   • Click “Create Service Account”
   • Name it chatbot-drive-uploader
   • Click “Create and Continue” → “Done”

Step 2: Download the key (≈1 minute)

1. Open the Service Account you just created
2. Go to the “Keys” tab
3. Click “Add Key” → “Create new key”
4. Choose JSON
5. Click “Create” (the file downloads automatically)
6. Rename it to service-account-key.json
7. Place it in the project root (next to google_drive_sync.py)

Step 3: Share the Google Drive folder (≈1 minute)

1. Create a folder in Google Drive (e.g., “Chatbot_Data”)
2. Right-click → “Share”
3. Open service-account-key.json, find client_email
   • Example: chatbot-drive-uploader@your-project.iam.gserviceaccount.com
4. Invite that email with “Editor” permission
5. Click “Send”

Step 4: Update the code (≈1 minute)

Open google_drive_sync.py and set:

SERVICE_ACCOUNT_FILE = "service-account-key.json"

Done! ✅

All data will now sync to your Drive folder automatically without manual intervention.

🔄 Alternative: Fix the OAuth client (refresh token flow)

If you prefer refresh tokens, create a new OAuth client.

Step 1: Create the OAuth client

1. Visit Google Cloud Console
2. Select your project
3. Left menu → “APIs & Services” → “Credentials”
4. Click “Create Credentials” → “OAuth client ID”
5. If prompted, configure the consent screen (choose “External”)
6. App name: Chatbot Drive Uploader
7. User support email: your email
8. Developer contact: your email
9. Click through “Save and Continue” to finish
10. Click “Create Credentials” → “OAuth client ID” again
11. Choose “Desktop app”
12. Name it Chatbot Desktop Client
13. Click “Create”
14. Copy the Client ID and Client secret

Step 2: Update the code

CLIENT_ID = "your new client id"
CLIENT_SECRET = "your new client secret"

Step 3: Fetch a new refresh token

python get_refresh_token.py

📝 Notes

• The Service Account JSON is sensitive — never commit it to Git
• Add service-account-key.json to .gitignore
• Service Accounts are safer because no user credentials live in code
