# Attach .ics file to event confirmation

With TuCalendi you can **attach an ics file to the confirmation of each event** booked by your customers.

## What is the ics format?

**ics is the worldwide standard format** used for calendar files in programs such as **Google Calendar**, **Microsoft Outlook** or **Apple iCalendar**. This format allows you to **import and export calendar entries** between different platforms.

## What is an .ics file?

The .ics file is **the file that contains information** such as the **event name**, **start time**, **duration** and even the **description** of the event, so that it can be understood and interpreted by the different calendar programs available on the market.

By using this TuCalendi feature in the **event confirmation emails** your customers receive, they can **confirm attendance** and **add the appointment to their calendar**. Activating this feature is very easy in TuCalendi.

> [!CAUTION]
> **IMPORTANT**: As of October 1, 2023, the **"Confirmation"** field no longer exists in the event options menu. This customization of the events must be done from the **workflows**.
> **It is necessary** to [create workflows](https://www.tucalendi.com/en/s/flows/how-to-create-a-workflow) to associate the **confirmation template** to your customers when they make a reservation with you.
