Telegram implementation to support **sending messages only**. Your Home Assistant instance does not have to be exposed to the Internet and there is no polling to receive messages sent to the bot.

To integrate this into Home Assistant, add the following section to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry

telegram_bot:
- platform: broadcast
api_key: <telegram api key>
allowed_chat_ids:
- 12345
- 67890
```

Configuration variables:

- **allowed_chat_ids** (*Required*): A list of user in the `user_id` Telegram format enabled to interact to webhook
- **api_key** (*Required*): The API token of your bot.
- **parse_mode** (*Optional*): Default parser for messages if not explicit in message data: 'html' or 'markdown'. Default is 'markdown'.

To get your `chat_id` and `api_key` follow the instructions [here](/components/notify.telegram/).

This component creates notification services to send, or edit previously sent, messages from a [Telegram Bot account](https://core.telegram.org/bots) configured either with the [polling](/components/telegram_bot.polling/) method or with the [webhooks](/components/telegram_bot.webhooks/) one, and trigger events when receiving messages.

If you don't need to receive messages, you can use the [broadcast](/components/telegram_bot.broadcast/) platform instead.

### {% linkable_title Notification services %}
Available services: `send_message`, `send_photo`, `send_document`, `send_location`, `edit_message`, `edit_replymarkup`, `edit_caption`, `answer_callback_query`.
