Google Calendar Integration
Scheduling & MeetingsWhat It Does
Google Calendar is the foundational scheduling infrastructure that commercial real estate teams build upon. Unlike booking tools like Calendly that face counterparties, Google Calendar is the backend system that stores your actual appointments, checks availability, syncs across devices, and integrates with virtually every scheduling and productivity tool you use. It's where your site tours, IC meetings, closings, capital-call deadlines, and personal appointments all live in one unified timeline.
Why Real Estate Professionals Use It
CRE schedules are uniquely chaotic: site tours booked last-minute, IC meetings that shift, capital-call deadlines that cannot slip, multi-party closings, and personal appointments mixed in. Google Calendar handles this complexity better than any industry-specific tool because it's designed for flexibility. You can move events by dragging, duplicate recurring pipeline reviews, share calendars with analysts and transaction coordinators, and access your schedule from phone, tablet, or desktop—all synced in real-time.

Feature
Multiple Color-Coded Calendars for CRE Activities
Create separate calendars for different activity types: 'Site Tours' (blue), 'Closings' (green), 'IC Meetings' (orange), 'Personal' (gray). Each calendar is a distinct layer you can toggle on/off for visual clarity. All events sync to the same master view.
Real Estate Impact
Glance at your week and instantly distinguish site tours (blue blocks) from closings (green). Hide personal appointments when sharing availability with brokers. Export the 'Site Tours' calendar to analytics tools for deal-pursuit tracking.

Automation Workflows
Ready-to-deploy workflows powered by Google Calendar + NextAutomation
Workflow 1 of 5
Intermediate
New Calendar Event → Auto-Populate Deal Details from CRM
When a team member manually creates a Google Calendar event with a deal address in the title (e.g., 'Tour - 123 Industrial Pkwy'), this workflow detects the new event, extracts the address, searches the CRM for that deal, and updates the calendar event description with deal terms, broker contact info, and tour instructions.
Trigger: Google Calendar: New Event Created (via polling or webhook)
Workflow Steps
1Analyst creates a calendar event: 'Tour - 123 Industrial Pkwy, Friday 3 PM'
2n8n polls Google Calendar every 5 minutes, detects the new event
3Extract the deal address from the event title using regex
4Query HubSpot or CRM for the deal with the matching address
+4 more steps
An analyst manually creates a calendar event and automation fills in all deal details. No need to copy-paste pipeline info—n8n does it automatically. The team arrives at the tour fully briefed without additional prep work.
Triggers & Actions
Connect Google Calendar to your workflows with powerful triggers and actions
Triggers
Event Created
Fires when a new event is added to a specified Google Calendar (your personal calendar, team calendar, or any you have access to).
Analyst creates a 'Closing - 456 Logistics Ct' event. Trigger a workflow to generate a diligence countdown checklist with milestone tasks and send the LP a timeline email.
Event Updated
Fires when an existing event is modified (time changed, description edited, attendees added).
Site tour rescheduled from 2 PM to 4 PM. Trigger a workflow to send an updated SMS to the broker: 'Our tour has been moved to 4 PM. New calendar invite sent.'
Event Deleted
Fires when an event is removed from the calendar.
Tour canceled in Google Calendar. Trigger a workflow to notify the broker via SMS, offer a reschedule link, and update the CRM deal stage to 'Tour Canceled'.
Event Starting Soon
Fires at a specified time before an event begins (e.g., 1 hour before, 30 minutes before). Useful for last-minute reminders or prep actions.
30 minutes before a tour, send SMS to the team: 'Your tour at 123 Industrial Pkwy starts in 30 min. Address: [full address]. Meet broker at the front office. Bring hard hats.'
Attendee Response (RSVP)
Fires when an event attendee responds to a calendar invite (Accepted, Declined, Tentative).
A committee member declines the IC meeting calendar event. Trigger a workflow to alert the deal lead: 'Committee member unavailable for the proposed IC date—reschedule needed.'
Actions
Create Event
Programmatically create a new Google Calendar event with title, start/end time, location, description, attendees, and reminders.
When a deal moves to 'Under Contract' in the CRM, create a Google Calendar event for the closing date with description: 'Diligence checklist: [tasks]' and invite the transaction coordinator.
Update Event
Modify an existing calendar event: change time, update description, add attendees, or change location.
When a seller drops the asking price, find all upcoming tours for that deal in Google Calendar and update event descriptions: 'PRICE DROP: Now $4.0M (was $4.25M), ~7.1% cap'
Delete Event
Remove an event from the calendar programmatically.
Deal goes under contract to another buyer. Query Google Calendar for all upcoming tours for that deal and delete them. Send SMS to affected brokers: 'That asset is now under contract. Let's look at similar deals in the submarket.'
List Events
Query calendar for events matching criteria (date range, search term, calendar ID). Returns list of events with full details.
Every Monday at 8 AM, query this week's tours from Google Calendar and generate a team digest email: 'This Week's Tours: [Deal 1 - Mon 2 PM], [Deal 2 - Tue 10 AM]...'
Check Availability (Free/Busy)
Query whether a specific time slot is available or blocked on the calendar. Returns free/busy status without revealing event details (useful for privacy).
Before assigning a tour to an analyst, check their Google Calendar availability for the requested time slot. Only assign if free; otherwise suggest an alternative team member or time.
Add Attendees to Event
Add email addresses to an existing event, sending them calendar invites.
A JV partner wants to join a scheduled site tour. Add the partner's email to the Google Calendar event; they receive a calendar invite with the deal address and details.
Set Event Reminders
Add or modify reminders for a calendar event (e.g., email 24h before, popup 30min before).
For all capital-call events, set reminders: 7 days before (email: 'Draft LP capital-call notices'), 1 day before (SMS: 'Capital call due tomorrow—confirm wire receipts'), 1 hour before (push notification).
Create Quick Event
Create event using natural language (e.g., 'Tour at 123 Industrial Pkwy tomorrow at 3pm'). Google Calendar parses and creates a structured event.
A chatbot or voice assistant captures a tour request: 'Schedule a tour at 789 Commerce Blvd Friday afternoon'. n8n uses Quick Event to parse and create the calendar entry automatically.
Setup Guide
Get started in approximately 10 minutes for OAuth setup; 20 minutes for calendar organization and first workflow
Prerequisites
- Google account with Google Calendar enabled
- Google Cloud project with Calendar API enabled
- OAuth2 credentials (Client ID and Client Secret) or Service Account JSON
- n8n instance with Google Calendar node available
1
Create Google Cloud Project
Go to console.cloud.google.com, create a new project (e.g., 'CRE Automation'). This project will house your API credentials.
Use a business Google Workspace account if possible. Free Gmail accounts work but have stricter API quotas.
2
Enable Google Calendar API
In your Google Cloud project, go to 'APIs & Services' → 'Library'. Search for 'Google Calendar API', click it, and click 'Enable'. This allows your project to access Calendar data.
You'll also want to enable 'Google Meet API' if you plan to create video conferencing links for IC and LP calls via automation.
3
Create OAuth2 Credentials
Go to 'APIs & Services' → 'Credentials' → 'Create Credentials' → 'OAuth client ID'. Choose 'Web application', add authorized redirect URI (your n8n instance URL + /rest/oauth2-credential/callback). Download JSON with Client ID and Secret.
For n8n Cloud, use their OAuth redirect URL. For self-hosted, use https://your-n8n-domain.com/rest/oauth2-credential/callback.
4
Connect Google Calendar to n8n
In n8n, add a Google Calendar node. Click 'Create New Credentials', select 'OAuth2', paste Client ID and Secret. Click 'Connect' and authorize access via Google OAuth flow. Test by adding a 'List Events' action.
During the OAuth flow, select your primary business calendar. You can add multiple calendar credentials in n8n to access different Google accounts (personal, team, firm).
5
Create Dedicated Calendars for CRE Activities
In the Google Calendar web interface, click '+' next to 'Other calendars' → 'Create new calendar'. Create: 'Site Tours', 'Closings', 'IC Meetings', 'Capital Calls'. Set different colors for each. Share team calendars with your firm's members.
Use a naming convention: '[Your Name] - Site Tours', '[Firm Name] - Team Calendar'. Makes it clear in shared calendar lists which calendar is which.
6
Configure Calendar Sync with Calendly or Cal.com
In your booking tool (Calendly, Cal.com), go to Settings → Calendar Sync and connect Google Calendar. Select which calendar to check for conflicts (your primary Site Tours calendar). This prevents double-booking.
Use separate Google Calendars for different event types. Calendly checks the 'Site Tours' calendar; personal events on the 'Personal' calendar won't block tour availability.
7
Build First Workflow: Daily Tour Digest
Create an n8n workflow: Schedule Trigger (daily 7 AM) → Google Calendar List Events (today's events) → Filter for events with 'Tour' in the title → Format into an email digest → Send via Gmail. Test by scheduling a test tour today.
Start with a simple digest. Later add: query the CRM for deal details, generate AI prep notes, attach site photos, calculate the optimized route between tours.
8
Set Up Event-Driven Workflows with Polling or Webhooks
The n8n Google Calendar node can poll for new/updated events every X minutes. Create a workflow: Trigger on new events → Filter for a specific calendar or keywords → Take action (create CRM record, send SMS, update tasks). Polling interval: 5-15 minutes is typical.
Google Calendar doesn't support native webhooks, so n8n uses polling. Set polling to 5 minutes for near-real-time automation. Lower intervals (1 min) consume more API quota.
