Switch from Service Account to OAuth2 for Google Calendar (Personal Gmail)
- Replace JWT service account authentication with OAuth2 refresh token flow
- Service accounts cannot create Google Meet links for personal Gmail accounts
- Update edge function to use OAuth2 token exchange
- Change database column from google_service_account_json to google_oauth_config
- Add helper tool (get-google-refresh-token.html) to generate OAuth credentials
- Update IntegrasiTab UI to show OAuth config instead of service account
- Add SQL migration file for new google_oauth_config column
OAuth2 Config format:
{
"client_id": "...",
"client_secret": "...",
"refresh_token": "..."
}
This approach works with personal @gmail.com accounts without requiring
Google Workspace or Domain-Wide Delegation.
