How to Create a URL Downloader Telegram Bot: Step-by-Step Guide for Beginners

Telegram is a popular messaging app that allows users to send messages, photos, videos, and other files to their contacts. However, sometimes it can be cumbersome to download large files, and that's where Telegram bots come in. Telegram bots are automated tools that can be programmed to perform a wide range of functions. One such function is to download files from a URL and provide users with a direct download link. In this article, we will explain how to create a URL downloader Telegram bot.

Step 1: Create a Telegram Bot

To create a Telegram bot, you will need to use the BotFather, which is a bot that helps you create and manage other bots. To get started, open the Telegram app and search for @BotFather. Once you have found it, start a chat and type /newbot to create a new bot. Follow the on-screen instructions to set a name and username for your bot.

Step 2: Set Up Your Bot's Profile Picture

Once you have created your bot, you can set up its profile picture. To do this, send a photo to your bot, and then use the command /setuserpic to set it as your bot's profile picture.

Step 3: Set Up Your Bot's Commands

The next step is to set up your bot's commands. Commands are special messages that users can send to your bot to trigger specific actions. To set up commands for your bot, use the command /setcommands. This will prompt you to enter a list of comma-separated commands and their descriptions.

Step 4: Install Required Libraries

To download files from a URL and communicate with the Telegram API, you will need to install some libraries. You can use pip to install the required libraries, including the Telegram Bot API and the requests library.

Step 5: Write Your Bot's Code

Now it's time to write your bot's code. In this example, we will use Python to write the code. The code will use the Telegram Bot API to receive URLs from users, download the file, and generate a direct download link to share with the user.

First, you will need to import the required libraries and initialize your bot's API key

Python

import telegram
import requests

TOKEN = 'YOUR_TELEGRAM_BOT_TOKEN'
bot = telegram.Bot(TOKEN)

Next, you will need to define a function that will handle incoming messages from users:

Python

def handle_message(update, context):
    chat_id = update.message.chat_id
    message_text = update.message.text

    # Download file from URL
    response = requests.get(message_text)
    filename = message_text.split("/")[-1]
    with open(filename, 'wb') as f:
        f.write(response.content)

    # Generate URL for file
    url = f"https://yourserver.com/{filename}"

    # Send URL to user
    bot.send_message(chat_id=chat_id, text=url)

This code defines a function handle_message that is called whenever a user sends a message to the bot. The function retrieves the message text and downloads the file from the URL using the requests library. It then generates a direct download link for the file and sends it back to the user.

Step 6: Test Your Bot

Once you have written your bot's code, you can test it by sending a URL to your bot. If everything is working correctly, the bot should download the file from the URL and send a direct download link back to you.

Step 7: Deploy Your Bot

To make your bot accessible to others, you will need to deploy it on a server. There are many ways to do this, but one popular option is to use a cloud hosting service like AWS or Google Cloud Platform. Once you have deployed your bot, you can provide your bot's username to others so they can start using it.

Here's how to deploy your Telegram bot on AWS using Amazon Elastic Compute Cloud (EC2)

1. Create an EC2 instance: Sign in to the AWS Management Console and navigate to the EC2 dashboard. Click the "Launch Instance" button and select an Amazon Machine Image (AMI) to use as your server's operating system. Configure the instance details, such as the instance type, storage, and security group.

2. Connect to your instance: Once your instance is running, you can connect to it using SSH. Open a terminal or command prompt and use the SSH command to connect to your instance. You will need to provide the private key associated with your instance.

3. Install dependencies: Once you have connected to your instance, you will need to install the necessary dependencies to run your bot's code. Use the package manager for your operating system to install Python and pip. Then, use pip to install the required libraries for your bot.

4. Upload your code: You can use the SCP command to securely copy your code from your local machine to your server. Alternatively, you can use a version control system like Git to clone your code repository on the server.

5. Run your bot: Once your code is uploaded to the server, you can run your bot's code using a command like python bot.py. Be sure to keep your bot running in the background using a process manager like pm2 or screen.

6. Configure your server's firewall: To ensure that your bot can receive messages from the Telegram API, you will need to configure your server's firewall to allow inbound traffic on the appropriate port. The default port for the Telegram API is 443.

7. Update your bot's webhook: Finally, you will need to update your bot's webhook to point to your server's IP address or domain name. You can use the Telegram Bot API to set the webhook URL for your bot. This will ensure that messages sent to your bot are forwarded to your server for processing.

Once you have completed these steps, your Telegram bot will be up and running on your AWS instance. You can test your bot by sending it a message from another Telegram account. If everything is working correctly, your bot should respond with a direct download link for the file at the provided URL.
