Notes

• Authentication is automatic - the router injects the OAuth token
• Use primary as calendarId for the user's main calendar
• Times must be in RFC3339 format (e.g., 2026-01-15T10:00:00Z)
• For recurring events, use singleEvents=true to expand instances
• orderBy=startTime requires singleEvents=true
