Create a Telegram bot with Python It's much more accessible than it might seem at first glance. You don't need to be a senior developer, have a thousand free hours, or set up a mega cloud infrastructure: with a little curiosity, a computer (or even your mobile phone), and a willingness to tinker, you can have your first bot up and running in a matter of minutes.
In this article you will see What exactly is a Telegram bot, what is it used for, and how to create one with Python step by step Using different approaches (with libraries, without libraries, and with no-code tools) and how to take it a little further: adding it to groups, using it in your company, hosting it in the cloud, automating tasks, monetizing it, and avoiding the typical mistakes made at the beginning.
What is a Telegram bot and why has it become so popular?
A Telegram bot is basically a automated account that responds to messages and commands without a person monitoring the chat. Telegram treats it like any other user, but in reality, there's a program behind the scenes that receives updates from the API and sends responses based on your programming or configuration.
These Bots are used to solve very specific tasks within the application: answer frequently asked questions, manage bookings, send alerts, launch surveys, moderate groups, retrieve data from other APIs (weather, stock market, cryptocurrencies, technical incidents), control IoT devices, or serve as a simple interface for more complex systems behind the scenes.
Unlike other messaging systems, bots in Telegram stand out because The API is very open, well-documented, and has few restrictions.You don't need to request special permissions or go through endless reviews to get your bot up and running: you talk to BotFather, get your token, and you can connect your code.
This very open philosophy has led to bots of all kinds appear: for personal finance, group task automation, games and trivia, bots that integrate Google Calendar, reminders, sending newsletters, controlling smart lights or control panels for servers, to name just a few examples.
The explosion of platforms no-code and low-code (Manybot, Chatfuel, Make, n8n, etc.) has also helped many people create bots without writing a single line of code. At the same time, the Telegram developer community maintains examples, libraries, and templates that make life easier for those who choose to use Python, Node.js, or PHP.
Basic requirements for creating a Telegram bot with Python
To set up your Python bot you need very few things, but it's important to have them. clear from the start so you don't go crazyThis is the bare minimum:
- Python 3 installed on your computer (Windows, macOS, or Linux). You can download it from the official Python website if you don't already have it.
- pip or pip3 operational to be able to install libraries from the command line. This is already integrated into most Python 3 installations.
- The python-telegram-bot library (or other alternatives) that simplify communication with Telegram servers.
- A bot token generated through @BotFather, which will be the key with which your script authenticates against the Telegram API.
It's also advisable that you have a certain basic terminal or console operation to move around folders, run scripts and, if you want to go a little further, install dependencies in a Python virtual environment.
Create your bot with BotFather step by step
The starting point is always the same: Create the bot within Telegram using BotFatherwhich is the official bot that manages the other bots. The process is simple and requires no technical knowledge.
- Open the Telegram app and search for the user @BotFather.
- Enter the chat and send the command / newbot to start the wizard.
- Choose a display name for your bot (it's what users will see at the top of the chat).
- Choose a unique username ending in botFor example: MyBotClimateBot. This identifier cannot be repeated, so you may have to try several options.
When you finish the wizard, BotFather will send you a message with the secret access tokenwhich will have a format similar to 123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11That token is your key to call the Telegram API as that bot.
It is important that store that token in a safe place And don't paste it into forums, public screenshots, or unsecured repositories. If it gets leaked, anyone could control your bot. In more serious projects, an environment variable or a configuration file that isn't uploaded to version control is used.
Preparing the Python development environment
With the bot created, it's time to prepare the environment so your script can seamlessly connect to Telegram serversThe usual workflow is to install Python, check out pip, and add the necessary libraries.
On most systems, it is sufficient to install Python 3 from python.org or your Linux distribution's package manager, and then use pip to add the library we'll use in the basic examples: python-telegram-bot.
The typical command would be something like pip3 install python-telegram-botDepending on your system and how you have Python installed, this may be sufficient. pip install python-telegram-bot Without the 3. This library takes care of managing the connection to the API, handling updates, command handlers, etc. for you.
If you want to properly encapsulate dependencies and not "clutter" the system, it is recommended to use Python virtual environments (venv). This way, each project has its own library versions, which avoids conflicts when working with several different bots or scripts on the same machine.
First Telegram bot with python-telegram-bot
Once you have the environment ready, it's time to write. the classic minimal example that responds to a commandWe will create a file, for example bot.py o tecsify.py, and we'll include a simple codebase that you can understand at a glance.
The general idea is always the same: You import the library classes, define the functions that respond to the commands, and associate each command with its handler. and you start a loop that continuously listens for updates coming from Telegram.
Modern versions of python-telegram-bot use a model based on ApplicationBuilder, CommandHandler and MessageHandler, along with asynchronous functions. A typical example of an echo bot might be:
- Define a function for responding to the /start command with a welcome message.
- Define another function that Repeat any text you receiveto easily check that everything is working.
- Create the application with the token provided by BotFather and register the handlers for commands and text messages.
- Run run_polling() so that the bot can start listening and responding.
This library-based approach makes it You don't have to worry about the low-level details from the Telegram API (request format, specific endpoints, parsing updates to JSON, etc.). For a first bot, this is the most recommended option, especially if you don't want to overcomplicate things.
Run the bot and test it on Telegram
Once you have created your Python file, the next step is launch the script from the terminalFirst, navigate to the folder where you saved the file, for example:
cd path/of/your/project
Next, run the appropriate Python command on your system, for example python bot.py o python3 tecsify.pyDepending on the name you gave the file, if everything is installed correctly, you'll see a startup message or the terminal will simply wait.
As long as the program remains active, the bot will be listening to new updates and respondingIf you want to stop it manually, you can usually just press Ctrl + C in the console to close the process.
To try it, open the Telegram app, search for your bot's name or username (the one you defined with BotFather) and type the command / startIf you've configured the code correctly, you should see your welcome message. You can then send any text to verify that the echo function is working properly.
Create a minimal bot with classic-style python-telegram-bot
In addition to the newer model with ApplicationBuilder, there is a well-known usage pattern that uses classes like Updater and CommandHandlerAlthough the library has evolved, this diagram helps to understand the basic structure of a Telegram bot with Python.
The general logic consists of defining a function associated with the command / start which sends a basic greeting text to the chat where the command was executed. Then an object is created Updater passing the bot's token and collecting its dispatch, which is the one that registers and manages all the handlers.
With this you can add a CommandHandler for /start pointing to your start function, start polling with updater.start_polling() and leave the script listening for new commands. It's a simple and straightforward example to see, in just a few lines, how a command translates into a reply message in a Telegram chat.
Interact with the Telegram API without specific libraries
If you want to delve a little deeper and understand what's happening underneath, you can also create your own bot without any specific library for TelegramInstead, you use a generic HTTP library like requests and you call the Telegram bot API directly using POST and GET requests.
The basic mechanism for sending a text message to a channel or chat would be to call the URL https://api.telegram.org/bot<TOKEN>/sendMessage passing parameters such as in the request body chat_id y textRequests allows you to do this in a single line, although it is usually advisable to save the response in a variable to check if the API has returned ok or an error.
If you want to see the raw response that Telegram sends, you can print the text of the answerwhich arrives in JSON format. Python also includes the module jsonwith which you can transform that string into a dictionary and check, for example, the field data['ok'] to find out if the call went well.
This low-level approach has the advantage that You control every API call in detailWithout any intermediate layers, it's perfect for simple scripts that want to send notifications to a channel or group from a scheduled task, server, or monitoring system. Furthermore, it's easy to add to cron or integrate into other languages ​​using the same HTTP request pattern.
Parameters and extra options when sending messages
When you use the Telegram API directly, you can send more than just plain text; there are also a number of other features. Optional parameters that fine-tune how that message is displayed in the app, and it's worth knowing if you want to provide a better user experience.
Some of the most useful parameters are, for example, parse_modewhich allows you to indicate whether the content is formatted as Markdown or as HTMLMany developers prefer HTML because underscores and other Markdown symbols can cause problems in certain situations.
You can also use disable_web_page_preview to prevent Telegram from generating a preview when you add a link, or disable_notification This allows the user to receive the message without sound or pop-up notifications. This is useful for bots that send out many alerts and could be annoying.
Other important parameters are reply_to_message_idwhich serves to indicate that a message is a response to a previous one, and reply_markupwhere you can define custom keyboards or inline keyboards. The latter opens the door to creating much richer conversational flows without the user having to type so much text.
Passing arguments to your script for more flexibility
A script that always sends the same message to the same chat can be useful for testing, but normally you want something more flexible, that is, to be able to specify which chat each message is sent to and what content is sent without touching the code each time.
For that you can take advantage of the module sys of Python and collect arguments from the command line. For example, you could make the first argument the chat_id and the second is the message text, so that your script receives something like: identifier and content in quotes.
With a small conditional statement checking that len(sys.argv) If your script has at least three positions (script name, chat_id, and message), you can construct the POST request to the API using those values, without needing to modify them within the file. This makes your script reusable for different channels, groups, and texts simply by changing what you write in the console.
Send images, audio, video, and documents with your bot
Beyond text, the Telegram API allows send all types of multimedia content From your bot: photos, voice notes, audio files, videos, video notes, and documents. Whether using the requests library or python-telegram-bot, the idea is always very similar: use the appropriate endpoint and the correct parameters.
For the images, you can go in two directions: send the URL of a photo that is already hosted or upload the file directly as part of the request. In the first case, you specify the parameter photo with the image direction and, optionally, a caption or caption. In the second one, you use the field files of requests to attach the binary file opened in read mode.
Something similar happens with audio: you can send a file like Voice (voice note, the typical circle that appears in chats) or as audio normal, which is displayed more like a music track. In both cases, adding a Optional caption and thumbnailwhich is usually a JPEG image with limited size and weight.
For videos, there is both the method of sendVideo like sendVideoNoteThe latter is intended for short, circular videos, like a "video note." In addition to the chat_id and the file, you can include parameters such as duration (clip duration) and length (video dimension, in this case the diameter of the circle).
And if you want to attach virtually anything (PDFs, ZIP files, spreadsheets, etc.), the API provides the method sendDocumentAt the code level, the structure is very similar to sending an audio file or a photo: the file is opened, the dictionary is built files with the document key and, if you want, a representative thumbnail is also added.
Using external APIs: weather bot example
One of the great advantages of Telegram bots is that They can connect to external services to provide real-time dataA classic example is the weather bot, which asks for your location and returns the weather information corresponding to that coordinate.
To achieve this, you can rely on third-party public APIs, such as OpenWeatherMap, which has a Python library called pyowmThe general process involves requesting an API key from the OpenWeatherMap website, installing pyowm with pip, and combining it with your bot to check the weather when the user requests it.
In a typical scenario, the bot will display a custom keyboard with a "Get Weather" type buttonWhen the user taps it, the bot asks them to send their location. Once received, pyowm objects are created with the latitude and longitude coordinates, the weather is checked, and a message is generated with the current status, temperature, location, and time.
To manage these interactions, some developers use the library twx.botapiwhich encapsulates the Telegram API calls and allows working with ReplyKeyboardMarkup to build that custom keyboard. Then it enters a loop that reads updates, filtering the new ones by their update_id and processing each message according to whether it is text or location.
Different ways to create a bot: code vs no-code
Telegram gives you so much freedom that you have several ways to Design your bot according to your technical level and the time you want to investNot everything involves programming from scratch; you can also use visual platforms or hybrid solutions.
If you know how to program or want to learn, the usual thing to do is to go for the own code in Python, Node.js or PHPPython shines for its simple syntax and the amount of documentation and examples; Node.js integrates wonderfully when you already have projects in JavaScript; and PHP remains useful in environments where there are already servers with this language deployed.
When you don't feel like writing code, or you want to validate an idea quickly, you can use tools no-code like Manybot, Chatfuel, Tars, Make or n8nThey usually offer block interfaces or flowcharts where you drag and drop conditions, questions, answers, and connections to other apps without writing programming syntax.
There are also intermediate solutions that combine spreadsheet-type Airtable or Google Sheets connected to Make or n8nso the bot reads and writes data from there. It's a very practical way to set up MVPs, small booking systems, or simple automations, and only move to custom development when the project requires it.
Where to host your bot and how to keep it running
It is worth clarifying an important point: Telegram is not running your bot's codeIt only provides the API and manages the sending and receiving of messages. The program you wrote must be running somewhere so that the bot can respond at any time, even while you are offline.
For that you need a server or hosting serviceWhether physical or in the cloud. There are free or freemium options popular among beginners, such as Replit or Render, which allow you to publish simple projects without initial cost and keep your script running (with certain resource limitations).
If you want something more stable and configurable, you can opt for providers such as DigitalOcean, Railway, or other VPS providers where you set up your own Python or Node.js environment. This gives you much more security if your bot is in production or if you need fine-grained control over the operating system, firewall, queuing system, etc.
In short, the idea is that your Python script (or whatever language you use) is always active in a controlled environmentConnecting to the Telegram API via polling or webhooks. In more complex environments, a web server like Nginx and frameworks like Flask or FastAPI are typically used to handle incoming Telegram requests via HTTPS.
How to add a Telegram bot to a group?
Once your bot is working in private chats, the next step is usually to integrate it into groups or channels so that you can interact with multiple people at once, moderate conversations, or provide real-time information to the entire community.
The process from the app is very straightforward: You search for the bot by name, go to its profile, and use the "Add to group or channel" option.From there you choose the specific group where you want to add it and, if Telegram asks you to, you confirm that you agree to the requested permissions.
It is essential to review the bot-specific permissions within the groupIf it should only respond to commands, make sure it can read and write messages; if it's going to act as a moderator, it needs administrator permissions to delete content, ban users, or pin messages, depending on what you want it to do.
Common examples in groups are the Anti-spam bots, those that automatically launch surveys, those that sync tasks with Google Calendar or collaborative work tools, and those that send scheduled reports (for example, a daily summary of metrics, incidents or news relevant to the team).
Using a Telegram bot in your business or professional project
Beyond the fun aspect, a well-designed bot can become a key piece of a company's digital strategyThe range of uses is very broad and, in many cases, cheap to implement compared to other solutions.
One of the most frequent cases is the 24/7 customer servicewhere the bot answers typical questions about shipping, schedules, rates, or policies, and only hands the conversation off to a human when it detects complex queries. It's also widely used for automate order tracking, allowing the user to check the status of a purchase or retrieve invoices without overwhelming the support team.
In sectors such as e-commerce, online academies or restaurantsBots facilitate bookings, registrations, class reminders, sending materials, managing raffles or promotional campaigns, and collecting data (e.g., satisfaction surveys) without friction for the user.
There are known cases of companies that have significantly reduced their operating costs and response times Leveraging Telegram bots, either directly or as a complement to their website and social media, and integrated with payment tools, CRMs, and email marketing platforms, allows them to create effective conversion funnels within the messaging app.
Common mistakes when creating a Telegram bot
When someone sets out to create their first bot, they often stumble upon the same mistakes over and over againMost of them are very easy to avoid if you know about them beforehand. Keeping them in mind will save you a lot of trouble.
The most classic mistake is building a bot without a clear function, focus or specific utilityIf you don't know exactly what problem it solves or what task it automates, the bot can easily end up being a toy that nobody uses. Clearly defining the purpose before programming will help you decide what commands, flows, and responses you need.
Another very common mistake has to do with the permissions when you add the bot to groups or channelsIf you don't give it the appropriate permissions, it will appear to malfunction: it won't see the messages, it won't be able to delete them, it won't be able to pin them... The same happens if you confuse the test chat_id with the final one; the bot may be sending replies to a different location than where you are looking.
Token management is also delicate: accidentally publishing the token in a repository, screenshot, or forum This leaves the door open for someone else to control your bot. It's recommended to store it in environment variables, non-versioned configuration files, and, if it gets leaked, regenerate it from BotFather as soon as possible.
Finally, there are those who consider development complete without doing minimum behavioral testsCheck what happens if the user sends unexpected data, types incorrect commands, sends unusually large files, etc. Testing a few real-world use cases before "launching" the bot helps to greatly refine the experience.
Monetizing a Telegram bot: options and considerations
Monetizing Telegram bots is possible, although it usually requires a slightly more elaborate approach than simply putting a pay buttonThe key is that the bot offers a clear and recurring value that someone is willing to pay for.
One of the most commonly used formulas is the premium access by subscriptionUsers can access basic features for free and unlock advanced options or exclusive content through a monthly or annual subscription. They can also limit the amount of free usage and unlock more capacity with paid plans.
Another common approach is to integrate payment gateways such as Stripe or PayPalThe bot can directly sell products, services, courses, digital books, consulting services, etc. It can also be used to support affiliate programs, recommending tools and services with affiliate links and generating commissions.
In the educational and content creation fields, many creators use bots to Deliver paid newsletters, structured lessons, daily challenges, or digital libraries Accessible only to those with an active subscription. The important thing here is to design a clear and user-friendly flow for signing up, canceling, and managing payments.
Final considerations
If you decide to charge for digital services through your bot, you need to respect data protection regulations (such as the GDPR in Europe)You must properly inform users about what information you collect, how you use it, and where it is stored, and comply with any applicable tax obligations in your country. Telegram also has terms of service that you should review if you plan to use its platform extensively.
From everything we've seen, it's clear that a Telegram bot developed in Python, whether using specialized libraries or directly accessing the API through HTTP requests, can go from a toy to a serious tool: It automates repetitive tasks, connects external services, improves customer service, integrates into groups and channels, can be hosted on different platforms, and even opens up revenue streams. if it is planned carefully and aspects such as permissions, token security, hosting and regulatory compliance are taken care of.
