Step-by-Step Instructions

Access Integration Settings

Click your workspace avatar in the bottom left corner, then select Settings from the dropdown menu. In the left sidebar, navigate to Integrations to view all available integration options.

Make sure you have admin permissions in your workspace to access integration settings.

Select Calendar Integration

Scroll through the integrations list and locate your preferred calendar service. Click on Google Calendar, Outlook Calendar, or Apple Calendar depending on your needs. Click the Connect button next to your chosen service.

Google Calendar integration offers the most robust features and sync options.

Authenticate Your Calendar Account

A new window will open prompting you to sign in to your calendar service. Enter your credentials and click Sign In. Review the permissions that ClickUp is requesting and click Allow or Accept to grant access to your calendar data.

Use the same email address for both ClickUp and your calendar service to avoid sync conflicts.

Configure Sync Preferences

Select which ClickUp spaces and lists you want to sync with your calendar by checking the appropriate boxes. Choose your sync direction: One-way (ClickUp to Calendar) or Two-way sync. Set your default calendar for new events and specify which task fields should appear in calendar events.

Start with one-way sync initially to avoid accidentally modifying tasks from your calendar.

Set Task Display Options

Configure how tasks appear in your calendar by selecting Display Options. Choose whether to show task names, due dates, assignees, and priority levels. Enable Smart Scheduling if you want ClickUp to automatically suggest optimal times for task completion based on your calendar availability.

Enable Calendar Views in ClickUp

Navigate to any list or folder in ClickUp and click View in the top toolbar. Select Calendar from the view options to see your integrated calendar data alongside ClickUp tasks. Toggle between different calendar views using Day, Week, or Month options.

Use filters to show only specific task types or assignees in your calendar view.

Test the Integration

Create a new task with a due date in ClickUp and verify it appears in your external calendar within a few minutes. If using two-way sync, create an event in your external calendar and confirm it syncs back to ClickUp. Check that task updates in ClickUp reflect in your calendar and vice versa.

Initial sync may take 5-10 minutes, but subsequent updates should appear within 1-2 minutes.

Common Issues & Troubleshooting

Calendar events not syncing to ClickUp

Check your sync settings are set to Two-way sync and verify your calendar permissions. Try disconnecting and reconnecting the integration in Settings > Integrations.

Tasks appearing multiple times in calendar

This usually occurs when you have multiple calendar integrations enabled. Go to Settings > Integrations and disable duplicate calendar connections or adjust your sync preferences to avoid overlapping calendars.

Authentication failed during setup

Clear your browser cache and cookies, then try the integration setup again. Ensure you're using the correct credentials and that your calendar service account has proper permissions enabled.

Calendar view not showing in ClickUp

Refresh your browser and ensure the calendar integration is properly connected. If the calendar view is still missing, try switching to a different view and back to calendar, or contact ClickUp support for workspace-specific issues.
