Upptime is a very useful tool for website uptime monitoring. If you are not getting notified when your websites are down, there is no point in tracking them in the first place.

Creating a bot is fairly easy. You can start the process by just writing to @BotFather and following the instruction. After the bot creation, you should have your bot token. You should also start the chat for your newly created bot with /start (or writing anything would work too).

By using your token you can retrieve the chat_id from the telegram api.

https://api.telegram.org/bot<token>/getUpdates

Replace <token> with your token and send a GET request to the url. The response will have your chat_id.

{
    "ok": true,
    "result": [
        {
            "update_id": 000000000,
            "message": {
                "message_id": 000000000,
                "from": {},
                "chat": {
                    "id": 00000000, // <- here
                    "first_name": "",
                    "username": "",
                    "type": "private"
                },
                "date": 0000000000,
                "text": "/start",
                "entities": []
            }
        }
}

Your chat_id will be in result[0].message.chat.id

If your chat id is correct you can retrieve chat history with; https://api.telegram.org/bot<token>/getChat?chat_id=<chat_id>

To verify that your bot can send messages; https://api.telegram.org/bot<token>/sendMessage?chat_id=<chat_id>&text=Hello

Last step is to add Github secrets to your repository.
