Quick Answer
Use Calendar Bridge to sync the third-party calendar into Google
Connect the unsupported calendar and your Google Calendar to Calendar Bridge. Set the third-party calendar as the Source and Google Calendar as the Destination. Then connect that Google account to BizStackPro and assign the correct Google Calendar.
Connecting Unsupported Calendars Without Breaking Your Scheduling System
Your team may use a calendar provider that BizStackPro does not connect to directly.
Calendar Bridge can act as a middle layer by syncing events from the third-party calendar into Google Calendar. BizStackPro can then use the connected Google Calendar to identify busy times and prevent scheduling conflicts.
If the sync direction, calendar assignment, or Google connection is configured incorrectly, BizStackPro may not recognize existing events. That can create inaccurate availability or double bookings.
This guide explains how to connect the calendars, configure the sync, connect Google to BizStackPro, and verify that busy times block availability correctly.
Calendar Bridge Integration at a Glance
How the Calendar Sync Works
Third-Party Calendar
This is the calendar provider that is not directly supported by BizStackPro.
Calendar Bridge
Calendar Bridge copies or synchronizes calendar activity between the connected calendar accounts.
Google Calendar
Google Calendar receives the synchronized events and becomes the calendar BizStackPro can read.
BizStackPro
BizStackPro uses the assigned Google Calendar to recognize busy times and calculate booking availability.
The connection depends on the complete chain
The third-party calendar must sync into Google, the Google account must be connected to BizStackPro, and the correct Google Calendar must be assigned to the account or user.
Before You Begin
Gather the calendar accounts and decide how events should move between them.
- Confirm which third-party calendar must be synchronized.
- Choose the Google Calendar BizStackPro will use.
- Confirm that you can sign in to both calendar accounts.
- Review the existing events in both calendars.
- Decide which calendar is the source.
- Decide which calendar is the destination.
- Review Calendar Bridge sync preferences.
- Confirm which BizStackPro account or staff user needs the calendar.
Review the sync direction carefully
Selecting the wrong source or destination can cause events to appear in the wrong calendar or prevent the intended calendar from blocking BizStackPro availability.
Step 1: Set Up Calendar Bridge
Create a Calendar Bridge Account
Visit CalendarBridge.com and create an account.
Connect the Third-Party Calendar
Select Connect Calendar Account and complete the connection for the unsupported calendar provider.
Connect Google Calendar
Connect the Google account and Google Calendar that BizStackPro will use.
Start the Calendar Sync
After both accounts are connected, select Start Syncing Calendars.
Select the Source
Set the third-party calendar as the Source.
Select the Destination
Set the connected Google Calendar as the Destination.
Choose the Sync Preferences
Review the available synchronization options and choose the settings that match your scheduling needs.
Save the Sync
Save the configuration and allow the calendars time to begin synchronizing.
Step 2: Connect Google Calendar to BizStackPro
Open Integrations
Open the integrations area in BizStackPro.
Settings → IntegrationsConnect the Google Account
Select Connect Google Account.
Complete Google Authorization
Sign in to the correct Google account and complete the permission prompts.
Confirm the Connection
Return to BizStackPro and verify that the Google account appears as connected.
Connect the same Google account used in Calendar Bridge
If a different Google account is connected to BizStackPro, the synchronized third-party events may not appear in the calendar BizStackPro is checking.
Assign the Connected Google Calendar
Connecting Google is only part of the setup. The appropriate Google Calendar must also be assigned where BizStackPro can use it.
Account Assignment
Assign the connected Google Calendar through the account’s calendar settings.
Settings → CalendarsUser Assignment
Assign the calendar to a specific staff user through the user’s calendar configuration.
Settings → My Staff → Select User → User Calendar ConfigurationVerify the calendar in your profile
Open My Profile → Calendar Settings and confirm that the linked Google Calendar appears and is selected.
Quick Verification Checklist
- Third-party events appear inside the connected Google Calendar.
- The correct Google account is connected under BizStackPro Integrations.
- The intended Google Calendar is assigned to the account or user.
- The selected calendar appears under My Profile calendar settings.
- Busy third-party events appear as busy in Google Calendar.
- Busy times block availability in the BizStackPro booking widget.
- New third-party events synchronize into Google.
- Removed or updated events synchronize as expected.
Test the Calendar Integration
Create a controlled test event and review the complete sync path.
Create a Test Event
Add a test event to the third-party source calendar during a time that would normally be available for booking.
Check Google Calendar
Confirm that Calendar Bridge synchronizes the event into the selected Google Calendar.
Open the BizStackPro Booking Page
Open the public booking link or embedded calendar as a visitor.
Check the Test Time
Confirm that the time occupied by the third-party event is not available for booking.
Update the Test Event
Change the event time in the source calendar and confirm the update reaches Google and BizStackPro availability.
Remove the Test Event
Delete the test event and confirm that the time becomes available again after synchronization.
Troubleshooting Calendar Bridge Integrations
Third-party events do not appear in Google Calendar
Review the Calendar Bridge connection, source calendar, destination calendar, sync preferences, and account authorization. Confirm that the sync is active.
Google is connected, but BizStackPro does not block busy times
Confirm that the correct Google Calendar is selected in the account or user calendar configuration. Also verify that the synchronized event is marked as busy rather than free.
The wrong Google Calendar is being checked
Open the user or account calendar settings and replace the selected calendar with the Google Calendar receiving the Calendar Bridge events.
Events take time to appear
Calendar synchronization may not be instantaneous. Allow the configured sync process to run, refresh both calendars, and check the event again.
Duplicate events appear in Google Calendar
Review the active Calendar Bridge syncs and make sure the same source calendar is not being sent to the same destination through more than one synchronization rule.
