Creating a Telegram bot to interact with
 
    The steps are as follows:
- Start chat with BotFather on desktop Telegram 
- create a new bot using - /newbot
- give the bot a name eg. Steven's Demo Bot 
- give the bot a username eg. StevensDemoBot 
- take note of the Telegram token 
- start a conversation with Steven's Demo Bot 
- hit the Telegram API - getUpdatesendpoint with your token eg- https://api.telegram.org/bot000000000:AAFjSq4AMkx1JkQS4woTlyKlXeftv6mgu-I/getUpdates
- if there's no update, add a message to the conversation again 
- visit the API again and take a note of the chat id 
- send an http request to - https://api.telegram.org/bot000000000:AAFjSq4AMkx1JkQS4woTlyKlXeftv6mgu-I/sendMessage?chat_id=000000000&text=Feed%20Meto send a message
Mainly I'm doing this in the context of a PHP Laravel application but it could totally be language agnostic.
Here's the simple Telegram service I use
<?php
namespace App\Services;
use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\Log;
class TelegramService
{
    public function __construct(
        private string $botToken = '',
        private string $chatId = ''
    ) {
        $this->botToken = $this->botToken ?: config('services.telegram.token');
        $this->chatId = $this->chatId ?: config('services.telegram.chat_id');
    }
    public function sendMessage($message): bool
    {
        $response = Http::post("https://api.telegram.org/bot{$this->botToken}/sendMessage", [
            'chat_id' => $this->chatId,
            'text' => $message,
        ]);
        if ($response->successful()) {
            Log::info("Telegram message sent successfully");
            return true;
        } else {
            Log::error("Failed to send Telegram message: " . $response->body());
            return false;
        }
    }
}
