# How to set up event notifications

You can set up event notifications to be sent to [Back Office users](/back-office-guide/system/users.md#users) through the following channels: email, SMS, Slack, or Telegram.

## Prerequisites

The following prerequisites are required before setting up event notifications:

* If you plan to send event notifications through Slack or Telegram, create and configure a corresponding bot, and then specify the bot token in the **Slack bot** or **Telegram bot** field on the **System** > **Settings** page.

  To learn how to obtain the bot tokens, refer to [How to set up a Slack bot](/how-to-articles/manage-communication-platforms/how-to-set-up-a-slack-bot.md) and [How to set up a Telegram bot](/how-to-articles/manage-communication-platforms/how-to-set-up-a-telegram-bot.md).
* If you plan to send event notifications as direct Slack or Telegram messages to Back Office users, specify for each user their Slack and Telegram identifiers in the **Slack chat Id** and **Telegram chat Id** fields on the [Back Office user details page](/back-office-guide/system/users.md#details).

  To learn how to get a user’s Telegram identifier, refer to [How to get Telegram chat, group and channel identifiers](/how-to-articles/manage-communication-platforms/how-to-get-telegram-chat-group-and-channel-identifiers.md).
* Create notification templates for each channel through which you plan to deliver event notifications. To do this, navigate to **System** > **Templates**, and then select a channel for which you want to create templates.

  To view the examples of email, SMS, Slack, and Telegram templates, refer to[Templates](/back-office-guide/system/templates.md).
