# Google Calendar connection

## Why Google Calendar is required

For all calendar-based workflows, the business owner must connect a Google Calendar account. The Google Calendar connection is essential because:

- The AI checks your **existing events** to avoid scheduling conflicts
- The AI creates **new events** when appointments are confirmed
- Both the business owner and customer receive **email notifications** through Google Calendar
- The Interlinked Calendar screen displays events from the connected Google Calendar

Without a connected Google Calendar, the AI cannot check availability, create events, or complete the booking flow. The calendar-based workflows will not function fully without this connection.

  <p><strong>Important</strong></p>
  <p>Connecting a Google Calendar is a required step for using any of the four calendar-based workflows (Qualify & Schedule, Qualify Pay & Schedule, Free Appointment, Paid Appointment). Make sure to complete this connection during setup or from AI Config.</p>
</div>

## Where to connect Google Calendar

There are two places to connect or manage your Google Calendar:

### Option 1 — From the setup wizard

The Google Calendar connection is part of the onboarding wizard's **Calendar connection** step. When you select a calendar-based workflow, the wizard guides you through connecting your Google account.

You can also return to this connection anytime by:

1. Going to [AI Config](/en/resources/docs/edit-your-setup-from-ai-config) at `https://panel.interlinked-ai.com/en/ai-config`
2. Clicking **Launch Wizard**
3. Opening the wizard at `https://panel.interlinked-ai.com/en/ai-config/wizard`
4. Navigating to the **Calendar connection** step

</div>

### Option 2 — From Connect Channels

You can also manage your Google Calendar connection from the channels management area:

1. Go to [AI Config](/en/resources/docs/edit-your-setup-from-ai-config) at `https://panel.interlinked-ai.com/en/ai-config`
2. Click **Connect channels**
3. Find the Google Calendar integration
4. Connect, reconnect, or disconnect from there

This path is useful when you want to manage all your connections (messaging channels and calendar) from one place.

## How the connection works

The Google Calendar connection is handled through **Google authorization** (OAuth). When you connect:

1. Interlinked opens a Google authorization window
2. You sign in to your Google account (or select an account if you have multiple)
3. You grant Interlinked permission to read and write events to your Google Calendar
4. The connection is established and the authorization token is stored securely

<div class="docs-callout docs-callout-note">
  <p><strong>Note</strong></p>
  <p>The connection uses standard Google OAuth, the same secure process used by other applications that integrate with Google Calendar. Interlinked only accesses your calendar for scheduling purposes — reading availability and creating appointment events.</p>
</div>

## What you can do with the connection

Once connected, you have three management options:

### Connect

Link a Google Calendar account for the first time. This is required before the AI can start booking appointments.

### Reconnect

If the connection expires or encounters an issue, you can reconnect by going through the authorization flow again. This refreshes the connection token and restores full functionality.

Common reasons to reconnect:

- The authorization token has expired
- You changed your Google account password
- You revoked access from your Google account settings
- The connection shows an error in the wizard

### Disconnect

Remove the Google Calendar connection entirely. When you disconnect:

- The authorization token is **removed** from Interlinked
- Interlinked's access to that Google Calendar account is **revoked**
- The AI will **no longer be able** to check availability or create events
- Existing appointments already on Google Calendar remain unchanged — they are not deleted

<div class="docs-callout docs-callout-warning">
  <p><strong>Important</strong></p>
  <p>If you disconnect Google Calendar while using a calendar-based workflow, the AI will not be able to book new appointments until you reconnect. Disconnecting does not delete existing appointments from Google Calendar.</p>
</div>

## Which Google Calendar is used

When you connect your Google account, Interlinked uses the **primary calendar** associated with that account. All availability checks read from this calendar, and all new appointment events are created on this calendar.

If your primary calendar contains personal events, they will be visible on the Interlinked Calendar as **Busy** events without revealing private details. See [Privacy and busy events](/en/resources/docs/privacy-and-busy-events) for how this works.

## Personal vs business Google Calendar

You can connect either a personal Google account or a Google Workspace (business) account. Interlinked works with both.

If you connect a personal account:

- Personal events are protected by the [Busy event privacy feature](/en/resources/docs/privacy-and-busy-events)
- The AI respects all events on the calendar when checking availability
- Team members using Interlinked see personal events as Busy, not with their real titles

If you connect a Google Workspace account:

- The same privacy rules apply
- Business events created by Interlinked are visible to your organization based on your Google Workspace sharing settings

## What to do next

- **Understand privacy** — Learn how personal events are handled when synced. See [Privacy and busy events](/en/resources/docs/privacy-and-busy-events).
- **Configure your schedule** — Set up business hours and exceptions. See [Business hours settings](/en/resources/docs/business-hours-settings).
- **Learn the booking flow** — Understand how the AI uses the calendar during conversations. See [How AI booking works](/en/resources/docs/how-ai-booking-works).
