OAuth Configuration Requirements

1. Publishing Status: Your application must be set to "In Production" in the OAuth consent screen

   • Go to Google Cloud Console → APIs & Services → OAuth consent screen
   • Under "Publishing status", select "In Production"
   • This is required for public access to your application

2. User Type: Must be set to "External"

   • This allows any Google account to authenticate
   • Internal user type is only for Google Workspace users

3. Required Information:

   • Application name
   • User support email
   • Application home page
   • Authorized domains (if needed)
   • Developer contact information

Common Scopes

• https://www.googleapis.com/auth/userinfo.profile - User profile information
• https://www.googleapis.com/auth/userinfo.email - User email information
• https://www.googleapis.com/auth/calendar - Google Calendar access
• https://www.googleapis.com/auth/drive - Full Google Drive access
• https://www.googleapis.com/auth/gmail.readonly - Gmail read-only access

Important Notes

• The application must be run on a web server (localhost is fine for development)
• You need to configure your Google Cloud Console project properly
• Some scopes may require verification from Google
• Always handle tokens securely and never expose them in client-side code
• Your application must be in "Production" status, not "Testing"
• Verification may be required for certain sensitive scopes
