Cloudron Notifications in Telegram

[manngobaum]

My goal is to interact with my Cloudron Instance via Telegram or other Chat protocols. I know there are already implementations for Uptime Kuma but I wanted to have more flexibilty and for the future also response endpoints in my messages (restarting an app or even Cloudron (it's not impleted yet)).

What it basically does is to fetch the Cloudron notifications of a certain status and to send a message to a Telegram Chat.
Therefore I set up a Telegram Bot (https://core.telegram.org/bots). Started a chat with this bot and used the following HTTP request to receive the chat ID which is needed for n8n:

https://api.telegram.org/bot{TELEGRAMBOT_API_KEY}/getUpdates

You also need an API Key to access your Cloudron (https://my.xxx.tld.de/#/profile) -> under API Tokens

And here is the code for the notifications to build the workflow in n8n:

{
  "nodes": [
    {
      "parameters": {
        "interval": 60
      },
      "name": "Interval",
      "type": "n8n-nodes-base.interval",
      "typeVersion": 1,
      "position": [
        460,
        300
      ]
    },
    {
      "parameters": {
        "url": "https://my.xxx.tld/api/v1/notifications?acknowledged=false&page=1&per_page=100",

            {

              "value": "Bearer {Cloudron_API_KEY}"
            }
          ]
        }
      },
      "name": "HTTP Request",
      "type": "n8n-nodes-base.httpRequest",

    },
    {

        "chatId": "{TELEGRAM_CHAT_ID}",
        "text": "=<b>What?</b>\n{{$node[\"Item Lists\"].json[\"title\"]}}\n\n<b>When?</b>\n{{$node[\"Item Lists\"].json[\"creationTime\"]}}\n\n<b>Message</b>\n{{$node[\"Item Lists\"].json[\"message\"]}}",

    },
    {

          }
        ]
      ]
    },
    "HTTP Request": {

        [
          {
            "node": "Item Lists",

            "index": 0
          }
        ]
      ]
    },
    "Telegram": {
      "main": [
        [
          {
            "node": "HTTP Request1",
            "type": "main",
            "index": 0
          }
        ]
      ]
    },
    "Item Lists": {
      "main": [
        [
          {
            "node": "Telegram",
            "type": "main",
            "index": 0
          }
        ]
      ]
    }
  }
}

I'll update this soon to include App downtimes with the possibilty to restart the App right away.
