Connecting it

• You provide: Google account (OAuth)
• Where to get it: Google Cloud Console → enable Google Calendar API → configure OAuth consent screen → Credentials → Create OAuth client ID. Calendar scopes are sensitive and need app verification for public use.
• Permissions/scopes: https://www.googleapis.com/auth/calendar.events, https://www.googleapis.com/auth/calendar.readonly

Account setup

• Account needed: A Google account plus a Google Cloud project with the Calendar API enabled.
• App registration: Create an OAuth 2.0 Client ID (Web application) in Google Cloud Console; configure the consent screen and declare the calendar scopes.
• Verification required: Calendar scopes are SENSITIVE (not restricted) — a public External app must complete Google OAuth app verification (no third-party security assessment). Internal Workspace-only apps are exempt.
• Testing: While publishing status is 'Testing', works for up to 100 added test users; refresh tokens expire in 7 days.
