Automate Posting New Google Calendar Events to Telegram

What This Automation Does

This workflow catches new Google Calendar events made by the user and sends their details to a Telegram chat.

It solves the problem of missing new event updates by posting details instantly without checking the calendar app manually.

The user gets quick, clear updates on new meetings directly in Telegram, so no event is missed.

The workflow works by checking Google Calendar every minute for new events.

When one appears, it takes the important info like name, description, time, location, and who created it.

Then it formats the details into a neat message and sends it to a chosen Telegram chat or group.

Who Should Use This Workflow

This is good for anyone managing busy schedules with Google Calendar.

It helps project managers, team leads, or anyone needing fast event alerts in Telegram chat.

Also useful for small groups who want to stay synced on all new meetings.

Tools Used in This Workflow

• Google Calendar API: To watch for new events created.
• Telegram Bot API: To send messages with event details.
• n8n Automation Platform: To connect the calendar and Telegram and run the workflow.
