Telegram webhooks


Telegram chatbot webhooks implementation as described in the Telegram documentation.

By default this integration sets your bot’s webhook URL automatically to https://<external_url>/api/telegram_webhooks with the external_url of your Home Assistant configuration using Telegrams setWebhook method.

This is one of two bot implementations supported by Telegram. Described by Telegram as the preferred implementation but requires your Home Assistant instance to be exposed to the internet. The other implementation method is Telegram polling, for which your Home Assistant instance does not have to be exposed to the internet.

Configuration

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

# Example configuration.yaml entry
telegram_bot:
  - platform: webhooks
    api_key: YOUR_API_KEY
    allowed_chat_ids:
      - 123456789 # example id of a user
      - -987654321  # example id of a group, starts with a -

Configuration Variables

allowed_chat_ids list Required

A list of ids representing the users and group chats that are authorized to interact with the bot.

api_key string Required

The API token of your bot.

parse_mode string (Optional, default: markdown)

Default parser for messages if not explicit in message data, either html or markdown.

proxy_url string (Optional)

Proxy URL if working behind one (socks5://proxy_ip:proxy_port).

proxy_params string (Optional)

Proxy configuration parameters, as dict, if working behind a proxy (username, password, etc.).

url string (Optional)

Allow to overwrite the external URL from the Home Assistant configuration for different setups (https://<public_url>:<port>).

trusted_networks string (Optional)

Telegram server access ACL as list.

Default:

149.154.160.0/20, 91.108.4.0/22

To get your chat_id and api_key follow the instructions here. As well as authorizing the chat, if you have added your bot to a group you will also need to authorize any user that will be interacting with the webhook. When an unauthorized user tries to interact with the webhook Home Assistant will raise an error (“Incoming message is not allowed”), you can easily obtain the users id by looking in the “from” section of this error message.
