Calendars & appointments

Pairing Google Calendar with Leadgains

Use this how-to to connect a Google account to Leadgains Calendars so that appointments and availability are properly synced.

Last updated: May 20, 2026 Estimated time: 5 minutes

Brief overview

The Google Calendar connection allows Leadgains to synchronize appointments with the user's calendar. This helps to avoid double bookings and ensures that new appointments are visible in the right place.

The connection is made per user. Every employee who works with his or her own Google Calendar must therefore link his or her own account.

Supplies

An active Google account.
Rights to open calendar settings.
Permission to mount Google Calendar with read and write permissions.

Important: preferably do not connect shared Google Calendar with unclear permissions. Use the personal agenda of the employee who manages bookings.

Step-by-step plan

Step 1 - Open Calendars

Open directly Calendars into app.ldgns.be, or go to the correct subaccount Calendars via the left navigation. Then click at the top Calendar Settings.

Open Calendars and select Calendar Settings — Open Calendars and go to Calendar Settings.

Step 2 - Go to Connections

Open the tab Connections. Then click AddNew to add a new calendar integration.

Open the Connections tab and choose Add New — Choose Connections and add a new calendar connection.

Step 3 - Choose Google Calendar

Search the list for Google Calendar and click Connect.

Google Calendar connect button in Leadgains — Click Connect next to Google Calendar.

Step 4 - Give Google permission

Select the correct Google Account and approve the requested permissions. Allow calendar access, profile data, and email access when Google requests it.

Accept Google permissions for calendar sync — Give all necessary permissions, including calendar read/write.

If write permissions are missing, synchronization may work incompletely. Use reconnect when Leadgains later shows a message about missing permissions.

Step 5 - Check the calendar choice

Choose which Google Calendar will be used as a linked calendar for bookings. If necessary, add other calendars as conflict calendars, so that existing occupancy prevents double bookings.

Common problems

The calendar does not sync.

Make sure all Google permissions are approved. Reconnect the integration when there is a message about missing permissions.

The correct Google Calendar is not listed.

Make sure the user is signed in with the correct Google account. If necessary, log out of other Google accounts and reconnect.

The connection used to work, but not anymore.

Possible causes include expired tokens, revoked Google permissions, or a deleted calendar. Reconnect the calendar and choose an active calendar.

Can a calendar be used by multiple users?

Do not use this as a standard solution. The connection is user-specific, so each user should connect their own Google Calendar.
