  • News monitoring – Monitor important current events and breaking news by extracting data from key Telegram channels. 85% of U.S. adults access news via mobile devices according to Pew Research.

This is just a taste of what‘s possible by tapping into Telegram data at scale. Next, let‘s look under the hood at how the Telegram API enables extraction.

Inside the Telegram API: Bots, MTProto, and Python Libraries

Telegram provides developers many options for building on top of their platform:

The Telegram Bot API

The Telegram Bot API allows creating bots that can be invited into groups, send messages, modify channels, and more. Over 2.5 million Telegram bots have been created.

Bots are relatively simple to develop in Python using libraries like python-telegram-bot. The Bot API uses a standard HTTP REST interface with JSON payloads.

For basic interactions, the Bot API provides what‘s needed. However, some limitations exist when it comes to data extraction:

  • Bots must be manually added to groups, limiting access
  • No way to programatically obtain full member lists
  • Rate limits can hamper large-scale data collection

For heavier scraping and automation, Telegram‘s MTProto API is more capable.

The Telegram MTProto API

MTProto is a custom protocol enabling Telegram‘s apps to communicate with Telegram‘s servers. It‘s fast, efficient, and provides the most complete access to Telegram‘s capabilities.

The MTProto API requires apps to act through an actual user account rather than a bot. Your app receives full user permissions to join groups, channels, and chats at will.

This makes MTProto ideal for unrestricted scraping and automation. Anything the Telegram app can do, your code using MTProto can as well.

Telethon: Python for Telegram Automation

If you want to leverage Telegram‘s MTProto API for data extraction and automation, the Telethon library for Python is the gold standard.

Key features of Telethon include:

  • Clean and idiomatic API wrappers for all MTProto methods
  • Full account control and sign-in capabilities
  • Utilities to easily serialize and deserialize MTProto responses
  • Async support to speed up mass data collection
  • Works with Python 3.6+

In my experience building Telegram automation, Telethon provides everything needed to quickly get up and running. Let‘s now dive into a hands-on scraping walkthrough using Telethon.

Scraping Telegram with Python: A Step-by-Step Walkthrough

To demonstrate the power of Telegram scraping, we‘ll build a Python script using Telethon to extract member details from a Telegram group.

While simple, this scraper template provides a blueprint for expanding to far larger Telegram automation projects.

Our script will:

  1. Connect to Telegram‘s API using our account credentials
  2. Retrieve our joined Telegram groups
  3. Allow picking a group to scrape
  4. Extract the member list from the chosen group
  5. Save the members to a CSV file

Let‘s get started!

Step 1 – Install Telethon and CSV Libraries

We‘ll need Telethon for API access and csv for saving our extracted data:

pip install telethon csv

(Note: It‘s recommended to use a virtual environment for each project)

Step 2 – Connect and Log In

First, we need to connect to Telegram‘s API with our account‘s credentials:

from telethon import TelegramClient, sync

api_id = 12345 
api_hash = ‘0123456789abcdef0123456789abcdef‘

client = TelegramClient(‘scraper_session‘, api_id, api_hash)

if not client.is_user_authorized():
  phone = ‘+15551234567‘ 
  client.sign_in(phone, input(‘Enter code: ‘))

This will prompt us to enter the verification code sent to the phone number to sign in.

Telethon handles session management automatically. Our account data will be persisted across runs.

Step 3 – Fetch Joined Groups

Next, we need to retrieve a list of groups we‘ve joined on Telegram using the GetDialogsRequest method:

from import GetDialogsRequest
from import InputPeerEmpty

result = client(GetDialogsRequest(
  hash = 0

groups = []  
for chat in result.chats:
  if chat.megagroup:

This will return up to 100 of our most recent groups and channels. We filter just for groups by checking megagroup is True.

Step 4 – Select Group to Scrape

Now we can select the specific group we want to scrape members from. We‘ll print out all our joined groups and let the user pick one by index:

target_group = None

print(‘Pick a group to scrape:‘)
for i, g in enumerate(groups):
  print(f‘{i} - {g.title}‘)

g_index = input(‘Enter group number: ‘)
target_group = groups[int(g_index)] 

Letting the user choose which group to scrape adds flexibility – no hardcoding needed.

Step 5 – Scrape Group Members

With our target group selected, we can extract all its members using client.get_participants():

print(‘Fetching members...‘)
all_participants = []
all_participants = client.get_participants(target_group, aggressive=True)

Setting aggressive=True removes some API restrictions and allows extracting very large groups without limits or gaps.

Step 6 – Save Results to a CSV

Finally, we‘ll save the member data to a CSV file for further analysis and usage:

import csv

print(‘Saving results to telegram_members.csv...‘) 

with open(‘telegram_members.csv‘, ‘w‘, encoding=‘UTF-8‘) as f:
  writer = csv.writer(f)
  writer.writerow([‘username‘, ‘user_id‘, ‘name‘])

  for participant in all_participants:  
    username = participant.username if participant.username else ""
    name = (participant.first_name + ‘ ‘ + participant.last_name).strip()

    writer.writerow([username,, name])

The final CSV will contain each member‘s username, ID, and name. From here, the data can be imported anywhere.

And we‘re done – in just over 60 lines of Python, we have a fully functioning Telegram group scraper powered by Telethon!

While basic, this script provides massive value. With some refactoring and enhancements, it could scrape thousands of groups at scale. Next, we‘ll look at some tips for taking Telegram automation to the next level.

Moving Beyond Basics: Proxies, Avoiding Bans, and More

While the basics of Telegram scraping are straightforward, you may run into issues as you scale up or extract more sensitive data. Here are some pro tips from my experience for smooth large-scale automation.

Use Proxies to Avoid IP Bans

If you scrape too aggressively from one IP address, Telegram may ban your IP temporarily.

Rotating different residential proxies is an effective solution to avoid bans and maintain high scrape rates.

Here is an example using Telethon‘s proxy support:

# Set a proxy 
proxy = {
  ‘proxy_type‘: ProxyType.SOCKS5, 
  ‘addr‘: ‘‘,
  ‘port‘: 1080,
  ‘username‘: ‘proxy_user‘, 
  ‘password‘: ‘proxy_pass‘ 

# Create client using the proxy
client = TelegramClient(

With proxies, you can rotate different IPs across multiple accounts to maximize results and reduce risk.

Use Multiple Accounts in Parallel

Another technique is running scrapers across multiple Telegram accounts in parallel.

For example, you could use multi-threading to process accounts in 10 parallel threads:

# Array of (phone, api_id, api_hash) for each account 
accounts = [
  (‘+15551111111‘, 1111111, ‘xxxxxxxxx‘),
  (‘+15552222222‘, 2222222, ‘xxxxxxxxx‘), 
  # ...

def scrape_account(account):
  phone, api_id, api_hash = account
  # Create client and scrape...

# Process accounts in 10 threads  
with concurrent.futures.ThreadPoolExecutor(max_workers=10) as executor:, accounts)

Spreading scrape volume across more accounts makes your automation more resilient.

Mimic Human Behavior

Telegram‘s spam detection looks for suspicious activity patterns. You‘ll achieve the best results by mimicking natural human behavior.

Tactics include:

  • Inserting random delays between actions to vary timing

  • Scrape at reasonable hours, not 24/7 requests

  • Stay under aggressive monthly message limits

  • Join groups and channels at an organic pace

Blending in like a normal user is ideal for avoiding disruptions.

Now that we‘ve covered automation best practices, let‘s discuss vital principles for ethics and transparency.

Scraping Responsibly: Best Practices and Ethics

Telegram offers a wealth of potential data. But ultimately, how you apply that data is what matters most.

Scraping ethically comes down to respecting user consent and privacy. Here are core principles to follow:

Only Extract Truly Public Data

Avoid scraping private groups or chats without express permission. Focus only on public groups and channels.

These have been opened to the broader Telegram community. But respect if private group admins request you stop collection.

Anonymize and Protect User Privacy

Best practice is to anonymize any personal information extracted, such as usernames.

Generalize data at the group level rather than assigning comments to specific users when possible.

Transparency Over Deception

Some scrapers use tricks like fake accounts to maximize data collection. A better approach is transparency.

Many public group admins will support scraping if you politely explain your research andIntended uses of the data. Build trust.

Minimum Viable Data

Only extract the minimal data needed for your specific use case. Don‘t overcollect "just because."

Document what data you‘ll need and what it will be used for in an ethics plan.

Follow Telegram‘s Terms of Service

Telegram provides flexible access. But you must adhere to their Terms of Service around acceptable use and automation.

Don‘t spam, don‘t harm users, and don‘t abuse their systems.

Credit Sources

If you publish insights based on Telegram data, properly credit the groups and channels they originated from when possible.

Scraping doesn‘t negate the important contributions of those communities.

Effective scraping brings value to businesses and consumers alike. By respecting these principles, we uphold the integrity of the open data Telegram provides.

Next Level Telegram Automation

This guide has only scratched the surface of the data goldmine Telegram holds for Python developers. Let‘s quickly recap the key insights:

  • Telegram usage is exploding – with 500M+ active users sending 8B+ messages daily, all accessible via developer APIs.
