# Telegram
Send notifications to Telegram using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.
## Setup
### Prerequisites
####
- A bot token. To get one, contact the [@BotFather](https://t.me/BotFather) bot and send the command `/newbot` and follow the instructions. Invite your bot to a group where you want it to send messages.
- The chat ID for every chat you want to send messages to. Invite [@myidbot](https://t.me/myidbot) bot to the group that will receive notifications, and write the command `/getgroupid@myidbot` to get the group chat ID. Group IDs start with a hyphen, supergroup IDs start with `-100`.
- Terminal access to the Agent you wish to configure.
### Configuration
#### File
The configuration file name for this integration is `health_alarm_notify.conf`.
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
```bash
