Automate Daily Google Calendar Events to Trello Cards

Description

Overview

This workflow automatically creates Trello cards for your daily Google Calendar events, helping you turn meetings and tasks into actionable Trello items without any manual effort. It ensures that your daily schedule seamlessly becomes a visual task board—ready for tracking, collaboration, and completion.

Use Cases

This automation is ideal for busy professionals and teams who rely on both Calendar and Trello. It saves time by syncing your events as organized Trello cards automatically.

Meeting Task Management:** Automatically create Trello cards for each calendar meeting, making it easy to add notes, next steps, and action items.
Daily Planning:** Every morning, your Trello board updates itself with that day’s meetings and key events.
Team Visibility:** Share daily priorities with your team by linking Google Calendar to a shared Trello board.

Good to Know

This workflow runs automatically every day at 8 AM, ensuring your Trello board always reflects your day’s schedule.

Required Setup:**

You must have valid connections for Google Calendar and Trello in n8n.
The workflow uses your Google Calendar to fetch events from the current day.
Recurring Events:** Routine meetings such as “Lunch” or “Check email” are automatically filtered out.
Environment Variables:** If you’re using a Trello link source, ensure the BASE_URL environment variable is defined (optional).

How It Works

This process begins with a daily trigger and flows through your Google Calendar, processing each event and creating a Trello card for actionable ones.

Trigger Every Day at 8 AM – Starts the workflow automatically each morning.
Get Start & End of Day – Calculates today’s date range (00:00 to 23:59).
Get Today’s Events (Google Calendar) – Fetches all events within that time range.
Split Events In Batches – Processes each calendar event individually.
Set Trello Card Details – Extracts event details such as title, description, and time.
Remove Recurring Tasks – Filters out repetitive or routine events.
Create Trello Cards – Creates a new Trello card for each relevant event.
Delete Task (No-Op) – Skips events that were filtered out.

How to Use

Follow these steps to set up and test your automation:

Configure Credentials: Connect your Google Calendar OAuth2 and Trello API credentials in n8n.
Verify Workflow Settings: Ensure the “Trigger Every Day at 8 AM” node matches your desired time zone.
Test the Workflow: Run manually or wait for the next scheduled time to verify Trello card creation.
Check Trello Board: Confirm that events appear as cards with correct names, descriptions, and due dates.
Adjust Filtering: Modify the “Remove Recurring Tasks” node to include or exclude more recurring events if needed.

Requirements

Google account with access to Google Calendar
Trello account with access to the target board
Proper OAuth2 authentication for both integrations
Workflow must remain active in n8n for automation to run

This flow can be easily extended for more advanced needs:

Add Labels:** Apply Trello labels automatically based on event categories.
Include Participants:** Append event attendees to Trello card descriptions.
Sync Back:** Add a “Mark Done” automation that updates Google Calendar events when Trello cards are completed.
