Overview

Trix Calendar integrations bring your schedule into your memory layer, enabling powerful features like AI-powered pre-meeting briefings, intelligent reminders, and unified calendar views across all your accounts.

Provider	Protocol	Key Features
Google Calendar	OAuth 2.0 + REST API	Real-time webhooks, multi-calendar, 60 req/min

Unique Feature: Pre-Meeting Briefings
Trix searches your memories for past interactions with meeting attendees and uses AI to generate actionable context before each meeting. No other calendar app offers this!

Key Features

Pre-Meeting Briefings

Before each meeting, Trix automatically searches your memory store for:

Past emails and conversations with attendees
Related notes and action items
Previous meeting outcomes
Relevant context from other memories

AI then synthesizes this into a concise briefing, so you walk into every meeting prepared with the right context.

Multi-Provider Unified View

Connect multiple calendar accounts and see all your events in one place:

unified-view.sh

# View upcoming Google Calendar events via CLI
trix google calendar list

# API: Get unified view across all providers
curl "https://api.trixdb.com/v1/integrations/calendars/upcoming?days=7" \
  -H "Authorization: Bearer YOUR_API_KEY"

Intelligent Notifications

Customize when and how you get reminded about upcoming events:

15 minutes before - Last-minute prep
1 hour before - Time to review and prepare
1 day before - Plan your day around important meetings
Daily digest - Morning summary of today's events

Multi-Calendar Support

Each provider supports multiple calendars. You can selectively enable which calendars to sync:

multi-calendar.sh

# List Google calendars via CLI

# API: List calendars from any connection
curl "https://api.trixdb.com/v1/integrations/connections/<connection-id>/calendars" \
  -H "Authorization: Bearer YOUR_API_KEY"

# API: Enable/disable specific calendars
curl -X PATCH "https://api.trixdb.com/v1/integrations/connections/<connection-id>/calendars/<calendar-id>" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "sync_enabled": true }'

Quick Start

1. Connect Your First Calendar

connect.sh

# Google Calendar via CLI (recommended for most users)
trix integrations connect google

# Microsoft Outlook (via dashboard or API)
# Visit app.trixdb.com → Settings → Integrations → Microsoft Outlook

# Apple iCloud (via dashboard or API)
# Visit app.trixdb.com → Settings → Integrations → Apple iCloud

2. View Your Upcoming Events

view-events.sh

# Show upcoming Google Calendar events via CLI
trix google calendar list

# API: Get upcoming events across all providers
curl "https://api.trixdb.com/v1/integrations/calendars/upcoming?days=7" \

# Or configure manually
trix notifications enable email 15    # 15 min before

Security & Privacy

Token Encryption

All OAuth tokens are encrypted at rest using AES-256-GCM with account-specific keys:

Tokens never stored in plaintext
256-bit encryption keys
Account isolation (tokens can't be used across accounts)
Automatic token refresh for expired credentials

OAuth 2.0 with PKCE

Google and Microsoft connections use OAuth 2.0 with Proof Key for Code Exchange (PKCE) to prevent authorization code interception attacks.

Apple App-Specific Passwords

Apple iCloud uses app-specific passwords, which can be revoked at any time from your Apple ID settings without affecting your main password.

Trix only requests the minimum scopes necessary: read-only access to calendar events. We never request write access unless you explicitly enable two-way sync.

Provider Comparison

Real-time sync	Webhooks	Webhooks	15-min polling
Multi-calendar	Yes	Yes	Yes
Rate limit	60 req/min	600 req/min	~30 req/min

Which Provider Should I Use?

Google Calendar - Best for most users. Easy setup, real-time updates, excellent reliability.

Solutions:

Check connection status: trix integrations status <connection-id>
Verify calendar is enabled via the API or dashboard
Trigger manual sync: trix integrations sync <connection-id>

Notifications Not Arriving

Symptom: Not receiving email reminders for events

Solutions:

Verify preferences: trix notifications list
Check spam/junk folder for emails from [email protected]
