A Super Simple Guide for Complete Beginners 🚀

Hey there! 🚀 Let's build something cool together—a Telegram bot that shortens long URLs. Don't worry if you're new to coding; we'll go step by step!

🎯 What Will Our Bot Do?

✅ Turn long URLs into short ones

✅ Create custom short URLs (choose your own nickname for a link!)

✅ Work directly in Telegram, just like chatting with a friend

🛠️ What You’ll Need

Python installed on your computer (Download here)
A Telegram account
A free API key from Shotcut

📝 Step-by-Step Guide

Step 1: Setting Up Your Tools

Install the required Python packages by running:

pip install python-telegram-bot shotcutap

Step 2: Getting Your Telegram Bot Token

Open Telegram and search for “BotFather”.
Send /newbot and follow the prompts:
- Choose a name (e.g., My URL Shortener)
- Choose a username (must end in bot, e.g., myurlshortener_bot)

BotFather will give you a bot token—save it somewhere safe!

Step 3: Getting Your Shotcut API Key

Go to Shotcut Developer Portal
Sign up for a free account
Get your API key from the dashboard

🧑‍💻 Step 4: Writing the Code

Create a new file bot.py and paste this code:

from telegram import Update
from telegram.ext import Application, CommandHandler, MessageHandler, filters, ContextTypes
from shotcut import ShotcutAPI

BOT_TOKEN = "paste_your_telegram_bot_token_here"  # Get this from BotFather
SHOTCUT_API_KEY = "paste_your_shotcut_api_key_here"  # Get this from Shotcut website

shortener = ShotcutAPI(api_key=SHOTCUT_API_KEY)

async def welcome_user(update: Update, context: ContextTypes.DEFAULT_TYPE):
    welcome_message = """
    👋 Hi there! I'm your URL Shortener Bot!
    Just send me any link, and I'll make it shorter for you!
    Type /help for more info.
    """
    await update.message.reply_text(welcome_message)

async def show_help(update: Update, context: ContextTypes.DEFAULT_TYPE):
    help_message = """
    📚 How to use me:
    1️⃣ Send a link to shorten it.
    2️⃣ Use /custom [URL] [name] for a custom short link.
    """
    await update.message.reply_text(help_message)

async def make_custom_link(update: Update, context: ContextTypes.DEFAULT_TYPE):
    if len(context.args) < 2:
        await update.message.reply_text("❌ Please provide a URL and custom name.")
        return

    original_link, custom_name = context.args[0], context.args[1]
    try:
        result = shortener.shorten_link(url=original_link, custom=custom_name)
        await update.message.reply_text(f"✨ Custom short link: {result['shorturl']}")
    except Exception as e:
        await update.message.reply_text(f"😔 Error: {str(e)}")

async def make_short_link(update: Update, context: ContextTypes.DEFAULT_TYPE):
    original_link = update.message.text.strip()
    if not original_link.startswith(('http://', 'https://')):
        await update.message.reply_text("🤔 That doesn't look like a valid link.")
        return

    try:
        result = shortener.shorten_link(url=original_link)
        await update.message.reply_text(f"✨ Short link: {result['shorturl']}")
    except Exception as e:
        await update.message.reply_text(f"😔 Error: {str(e)}")


def start_bot():
    print("🚀 Starting Telegram Bot...")
    app = Application.builder().token(BOT_TOKEN).build()
    app.add_handler(CommandHandler("start", welcome_user))
    app.add_handler(CommandHandler("help", show_help))
    app.add_handler(CommandHandler("custom", make_custom_link))
    app.add_handler(MessageHandler(filters.TEXT & ~filters.COMMAND, make_short_link))
    app.run_polling()

if __name__ == '__main__':
    start_bot()

🚀 Running Your Bot

Save Your Secret Tokens
- Replace paste_your_telegram_bot_token_here with your Telegram bot token
- Replace paste_your_shotcut_api_key_here with your Shotcut API key
Start Your Bot

   python bot.py

You should see “Your bot is ready!” 🎉

Test Your Bot
- Open Telegram and find your bot
- Try /start, /help, sending a link, and /custom commands

🔍 Troubleshooting

Issue	Solution
Invalid Token	Ensure your bot token is correct & has no spaces
Links not working	Make sure they start with `http://` or `https://`
Bot not responding	Restart the bot (`Ctrl+C` then `python bot.py`)

🔒 Keep Your Bot Secure

Never share your bot token or API key
Store your credentials in a safe place
Be careful about the links you shorten
