How to Automatically Create ClickUp Tasks From Google Calendar Events Using Make.com

Introduction

A missed calendar update creates a cascade of manual work: someone has to copy meeting details into ClickUp, add assignees, set a due date, then tell the team in Slack. That turns minutes into friction and makes handoffs unreliable.

This simple Make.com automation solves that problem. When a Google Calendar event is created or updated, Make.com creates or updates a ClickUp task with the right assignee and due date, and posts a short Slack message. You get faster handoffs, fewer transcription errors, and a consistent operational pattern your team can trust.

If you want a similar routing pattern for bookings, see our guide on creating ClickUp tasks from Calendly bookings How to Create ClickUp Tasks from Calendly Bookings Using Make.com and Slack. For alerting on ClickUp status changes, we use the same Slack notification ideas in How to Automatically Notify Slack When a ClickUp Task Changes Status Using Make.com.

What You'll Need

• Google Calendar account with the calendar you want to monitor
• ClickUp account with access to the target Space, Folder, and List
• Make.com account (free for light testing, paid recommended for production polling/webhooks)
• Slack workspace and channel where you want notifications
• Optional: a Google Sheet for logging created task IDs (useful for idempotency)

Note: Use Google Calendar webhooks (Push notifications) if you want near-instant triggers. For simplicity and reliability, this guide uses Make.com’s Google Calendar watch trigger.

How It Works (The Logic)

When an event is created or updated on the chosen Google Calendar, Make.com picks up the event, extracts the meeting title, start time, attendees, and description. The scenario then either creates a new ClickUp task or updates an existing task tied to that calendar event. Finally Make.com posts a concise Slack message with the task link and key details.

Trigger (Google Calendar event) → normalize fields → create or update ClickUp task → Slack notification → (optional) log to Google Sheets

Step-by-Step Setup

1. Decide what calendar events should create tasks

Pick a single calendar to start. Decide if all events, or only events with a specific keyword in the title (for example, "Project:"), should create tasks. Filtering here reduces noise.

2. Create a new Scenario in Make.com and add the Google Calendar trigger

• Module: Google Calendar, "Watch Events".
• Configure to watch the calendar and event types (Created, Updated). For testing, you can run manual scenarios first.

3. Normalize the event data

Add a Tools/Formatter step (or simple mapping) to extract:

• event_id
• summary (title)
• description
• start_time (ISO)
• end_time (ISO)
• attendees (emails)

Convert start_time into the timestamp format ClickUp expects, or use an ISO field if ClickUp accepts it directly. Use Make.com date functions to convert timezones as needed.

4. Implement idempotency logic (optional but recommended)

If you want to avoid creating duplicate tasks for repeated updates, keep a lightweight Google Sheets log keyed by the Google Calendar event_id. Before creating a task, search the sheet for the event_id. If present, retrieve the stored ClickUp task_id and update the existing task instead of creating a new one.

5. Create or update the ClickUp task

• Module: ClickUp, "Create a Task" or "Update a Task".
• Task name: use the event summary, for example "Meeting: {{summary}}".
• Description: include summary, description, start time, end time, and the full Google Calendar event link.
• Due date or start date: map from start_time. If you prefer tasks due on the event date, set due_date accordingly.
• Assignees: map the primary attendee or a default assignee. If the attendee does not match your workspace user list, use a default bucket user and add the attendee email in the description.

If the Google Calendar event_id exists in your log, use the stored ClickUp task ID to update the task. If not, create a new task and append the returned task ID to the Google Sheets audit log with the event_id.

6. Post a Slack notification

• Module: Slack, "Post message" to a channel such as #delivery or #project-updates.
• Message format:

New task from Calendar
{{summary}}
When: {{start_time_local}}
Assignee: {{assignee_name_or_default}}
ClickUp: <{{task_url}}|Open task>

Use a brief message so the channel stays scannable. For important events you can @mention the assignee.

7. Test and tune timezone handling

Calendar times can be tricky. Test with attendees in different timezones and confirm ClickUp displays the expected start/due time. Use Make.com timezone conversion where needed, and store ISO timestamps in task descriptions for clarity.

8. Turn on the Scenario and monitor

Enable the scenario and monitor the first 24–48 runs. Look for:

• Duplicate tasks (fix by tightening the event_id lookup)
• Missing assignee mappings (add a fallback rule)
• Slack message formatting edge cases (especially long descriptions)

Real-World Business Scenario

A professional services firm used this flow to streamline handoffs between sales and delivery. Every client kick-off meeting created a task in the delivery List with the meeting time as the task start date and the client as the description. Delivery saw the task before the meeting, prepared materials, and the Slack alert prompted the project lead to confirm availability. The result: fewer missed handoffs and a standard prep process for every kickoff.

If you already handle bookings from Calendly, compare this pattern to our Calendly → ClickUp guide How to Create ClickUp Tasks from Calendly Bookings Using Make.com and Slack and reuse the same ClickUp mapping ideas.

Common Variations

• Only create tasks for events with a specific keyword or calendar invitee domain
• Create a checklist inside the ClickUp task using an approved template for recurring meeting types
• Create subtasks for each agenda item extracted from the calendar description
• Post the digest of all events created each morning to a Slack channel instead of one-by-one notifications

Conclusion

This Google Calendar → ClickUp → Slack automation removes the manual steps that turn small scheduling changes into coordination overhead. Start small, use event_id-based idempotency, map one or two reliable fields, and add a Google Sheets audit log if you want traceability.
