OpenClaw Google Calendar Integration: Scheduling Automation Guide

Why Connect Google Calendar to OpenClaw?

Your calendar is the backbone of your daily operations. By connecting it to OpenClaw, you transform your AI agent from a reactive chat assistant into a proactive scheduling partner that understands your time commitments, conflicts, and priorities.

Without calendar integration, if you ask your agent "Am I free at 3 PM tomorrow?" it has to guess. With calendar integration, it checks your actual schedule and gives you a definitive answer. It can also cross-reference calendar data with your email (someone mentioned a meeting in an email — is it on your calendar?), your CRM (prep notes before a client meeting), and your messaging channels (send you a WhatsApp reminder 15 minutes before).

Calendar integration is one of the most impactful integrations you can set up in OpenClaw because it touches almost every workflow — sales calls need scheduling, project work needs time blocks, personal life needs balance with work commitments. An agent with calendar access can make intelligent decisions about all of these.

Setting Up the Integration

Step 1: Enable the Google Calendar plugin. In the OpenClaw web dashboard, navigate to Integrations and find "Google Calendar." Click "Enable."

Step 2: Create Google OAuth credentials. You need OAuth 2.0 credentials from Google Cloud Console:

1. Go to console.cloud.google.com
2. Create a new project (or select an existing one)
3. Navigate to APIs and Services, then Credentials
4. Click "Create Credentials" and select "OAuth 2.0 Client ID"
5. Set the application type to "Web application"
6. Add http://localhost:18789/auth/google/callback as an authorized redirect URI
7. Copy the Client ID and Client Secret

Step 3: Enable the Google Calendar API. In Google Cloud Console, go to APIs and Services, then Library. Search for "Google Calendar API" and click "Enable."

Step 4: Add credentials to OpenClaw. Add these to your .env file:

GOOGLE_CLIENT_ID=your-client-id.apps.googleusercontent.com
GOOGLE_CLIENT_SECRET=your-client-secret
GOOGLE_REDIRECT_URI=http://localhost:18789/auth/google/callback

Step 5: Authorize. Restart OpenClaw, then go to the Google Calendar integration page in the dashboard. Click "Connect Google Account." You will be redirected to Google's OAuth consent screen. Log in with your Google account and grant calendar access. OpenClaw stores the access token and refresh token securely.

Step 6: Select calendars. After authorization, OpenClaw displays all available calendars. Choose which ones the agent should read and which it can write to. You might give it read access to all calendars but write access only to your primary calendar.

Calendar Commands You Can Use

Once connected, you can interact with your calendar through natural language. Here are examples of commands OpenClaw understands:

Querying your schedule:

• "What's on my calendar today?"
• "Am I free tomorrow between 2 and 4 PM?"
• "What meetings do I have this week?"
• "When is my next meeting with Sarah?"
• "Show me all events for next Monday"

Creating events:

• "Schedule a meeting with John tomorrow at 2 PM for 1 hour"
• "Block off Friday afternoon for deep work"
• "Create a recurring weekly standup every Monday at 9 AM"
• "Add a lunch with Emily next Thursday at noon at The Blue Cafe"

Modifying events:

• "Move my 2 PM meeting to 3 PM"
• "Cancel tomorrow's team lunch"
• "Add a Zoom link to this afternoon's client call"
• "Extend the project review by 30 minutes"

Intelligent scheduling:

• "Find a 1-hour slot this week for a meeting with the design team"
• "What's my most open day this week?"
• "Schedule 3 hours of focus time this week, avoiding mornings"

Automated Daily Briefings

One of the most popular calendar workflows is an automated morning briefing. Set up a cron job that runs at your preferred wake-up time and delivers your daily schedule summary:

# Cron: every day at 7:00 AM
0 7 * * * openclaw run daily-briefing

The daily-briefing skill pulls your calendar events for the day, cross-references them with email (any emails from meeting attendees?), checks for conflicts, and delivers a structured summary to your preferred channel — WhatsApp, Telegram, email, or iMessage.

A typical briefing looks like this:

Good morning. Here's your day:

9:00 AM — Team standup (30 min, Zoom)
10:00 AM — Client call with Acme Corp (1 hr, Google Meet) — Note: Sarah emailed last night asking to reschedule. Want me to respond?
12:00 PM — Lunch with Mike (1 hr, The Blue Cafe)
2:00 PM — 4:00 PM — Focus time (blocked)
4:00 PM — Sprint review (1 hr, Zoom)

You have 5 events today. No conflicts detected. 2 hours of focus time blocked.

This saves 5-10 minutes of manual calendar checking every morning and proactively surfaces issues (like Sarah's reschedule request) that you might otherwise miss until the meeting starts.

Conflict Detection and Resolution

OpenClaw can automatically detect and flag calendar conflicts. There are two modes:

Reactive conflict detection. When you ask OpenClaw to create or move an event, it automatically checks for conflicts before making changes. If there is a conflict, it tells you and suggests alternatives:

"I can't schedule the meeting at 2 PM — you have a client call from 1:30 to 3:00. Want me to schedule it at 3:00 PM instead, or find another open slot this week?"

Proactive conflict monitoring. Set up a cron job that periodically scans your calendar for new conflicts (which can happen when someone else adds events to shared calendars):

# Check for conflicts every 30 minutes
*/30 * * * * openclaw run conflict-check

When a conflict is detected, the agent alerts you and suggests resolution options — reschedule one event, shorten one event, or convert to an async format.

Automated Meeting Prep

For each meeting on your calendar, OpenClaw can prepare context-rich briefing notes. This is especially valuable for sales calls, client meetings, and recurring check-ins.

Set up a meeting prep cron job that runs 15-30 minutes before each meeting:

# Run meeting prep every 15 minutes
*/15 * * * * openclaw run meeting-prep

The meeting-prep skill checks if any meetings start in the next 30 minutes and, for each one, gathers relevant context:

• Attendee information from your CRM or contacts
• Recent email threads with attendees
• Notes from previous meetings with the same people
• The meeting agenda (from the calendar event description)
• Any pending action items related to the meeting topic

The prep notes are delivered to your preferred channel so you walk into every meeting informed and prepared.

Advanced Scheduling Workflows

Time blocking. Tell your agent to automatically block focus time on your calendar based on your preferences: "Block 2 hours of focus time every morning this week, but not on days with client calls before noon." The agent analyzes your calendar, finds suitable slots, and creates events.

Scheduling links integration. If you use Cal.com, Calendly, or another scheduling tool, OpenClaw can monitor your calendar for newly booked meetings and automatically trigger workflows — send a confirmation message, prepare notes on the attendee, or add a follow-up task after the meeting.

Cross-timezone scheduling. When scheduling with people in different time zones, tell your agent both names and it will find overlapping availability: "Find a 1-hour slot next week that works for both me and our Tokyo team" — the agent accounts for both time zones and suggests options in your local time.

Post-meeting follow-up. Set up a workflow that triggers after meetings end. The agent can prompt you for meeting notes, send follow-up emails to attendees, create action items in your task manager, and schedule the next meeting if applicable.

Troubleshooting

OAuth token expired. Google OAuth tokens expire after 1 hour, but OpenClaw automatically uses the refresh token to get new access tokens. If you see authentication errors, re-authorize by going to the Google Calendar integration page and clicking "Reconnect." If the problem persists, check that your Google Cloud project has the Calendar API enabled and that your OAuth credentials have not been revoked.

Events created in wrong calendar. Check the default calendar setting in the Google Calendar integration configuration. You can specify which calendar new events should be created in. If not specified, events go to the primary calendar.

Agent can't see shared calendars. Shared calendars must be subscribed to in your Google Calendar settings (visible in the left sidebar of Google Calendar web app). OpenClaw can only see calendars that appear in your calendar list.

Timezone mismatches. Ensure your OpenClaw timezone setting matches your Google Calendar timezone. Check your .env file for TZ=America/New_York (or your timezone). Mismatched timezones cause events to appear at wrong times.

Calendar API quota exceeded. Google Calendar API has usage quotas (1 million requests per day for free tier — more than sufficient for personal use). If you somehow exceed this, check for infinite loops in cron jobs or skills that poll the calendar too frequently.
