Telegram mini-applications are convenient and easy—to-use programs that work inside the messenger, allowing users to perform various actions without leaving the application. And if you want to learn how to create your own mini-application and use the capabilities of AdsGram, then this article is for you!
How do I create a mini-application in Telegram?
Mini apps can be very different: from games and useful tools to services for work and communication. Their main advantage is a user—friendly and simple interface that users already know and know how to use.
Let’s look at how to make your own mini-application and what tools and technologies you will need for this.
Preparation for development
This stage determines how convenient and useful your application will be. Don’t worry, the process is quite simple, and even if you have no experience, you can figure it out.
1. Defining the purpose of the mini-application
First of all, think about why you need a mini-application. It can be:
The game is designed to entertain users and increase engagement.
A useful tool (for example, a calculator, translator, or task scheduler).
A service for communication (for example, a chatbot to help clients or an automated FAQ).
It is important to understand what problem you want to solve with your mini-application. The clearer the goal, the easier it will be to develop its structure and functionality.
2. Choosing the development platform and technology
Now that you have decided on a goal, it’s time to choose what you will develop your application on. Here are some popular options:
JavaScript. If you know basic JavaScript, you can use it to create a mini-application. Telegram supports this technology, and it is quite convenient for a quick start.
React. It is a library for creating user interfaces. It is great for developing mini-applications, as it simplifies the creation of components and user interaction.
Other web technologies. You can also use HTML and CSS to create the interface of your application. These basic elements will help make your project visually appealing and functional.
Don’t be afraid to experiment. If you have experience with other frameworks or libraries, try them out. The main thing is that they support integration with the Telegram API.
3. Create a Telegram account and connect BotFather
Now that you are ready to develop, you need to create a bot that will manage your mini-application. This is done through the official Telegram bot — BotFather. He is, in fact, the main “administrator” of all bots in Telegram and helps you easily create and configure your application.
Here’s how to do it:
Open Telegram and find BotFather (you can just enter his name in the messenger search).
Start a chat with BotFather and enter the /newbot command.
Next, you will need to come up with a name for your bot (this is how it will be displayed to users) and a unique username. It should end in bot, for example, MyCoolMiniApp_bot.
After creation, BotFather will give you a token — this is the key with which you can control your bot via the Telegram API. This token is important, save it somewhere safe, because without it you will not be able to connect the mini-application.
This process takes only a couple of minutes, and already at this stage you will have a bot ready with which you can start integration.
When you have a bot, you can move on to the next stage — the development of the interface and functionality of your mini-application. Next, we will look at exactly how to use the Telegram token and API to create a unique and user-friendly application, as well as integrate it with AdsGram for promotion.
Development of a mini-application
To develop your Telegram mini-application, you can use different frameworks, such as React, or create an application from scratch using JavaScript and the Telegram API.
Remember, everything is not as difficult as it may seem at first glance.
Step #1. Creating a project
First you need to create a project — this will be the base of your mini-application. Text editors or development environments (IDEs) such as VS Code, WebStorm, or even simple editors like Sublime Text will help you with this. They help organize the code and make writing it more convenient.
Create a folder for your project and create files inside:
index.html — this is the file that will contain the HTML code of your mini-application.
style.css is a file with styles (CSS) for the interface design.
app.js — here will be your main JavaScript code that will control the application logic and interaction with the Telegram API.
Step #2. Writing code
When the project structure is ready, you can move on to the code. Let’s look at how to set up your bot and make it interactive.
Connecting to the Telegram API
Use the token that you received from BotFather and connect it in your code to set up interaction with Telegram. If you are using JavaScript, connect the Telegraf library.js — it simplifies working with the Telegram API and makes it easy to send and receive messages.
Install Telegraf using the command:
Now create a simple bot:
This code launches a bot that will greet all users at startup. Then you can add more functions, such as processing text commands or button clicks.
Creating an interface
If your mini-application interacts with users through the interface, you need to add the HTML code to the file index.html . For example, if you have a mini-game, create buttons and input fields:
Step number 3. Writing application logic
Now let’s move on to the app.js, where all the application logic will be located. For example, you can add button click processing:
The interface of your mini-application should be simple and intuitive so that users do not get lost and can quickly figure out how to use it.
Step #4. Launch and testing
When everything is ready, you need to test how your mini-application works. There are several options here:
Start a local server using Live Server in VS Code or another tool. This will allow you to immediately see the changes and test the functionality.
If you want to do everything for real and test the application in Telegram, deploy it on a platform like Heroku or Vercel. This will allow your bot to work in real conditions and accept requests from users.
To run the bot on the server, create a server file.js and use code like this:
That’s all! Your mini-application is ready for testing and launch. All that remains is to optimize it and add new features so that users get the most pleasure and benefit. And with AdsGram, you can immediately start an advertising campaign to attract more users and get a response to your application.
How do I add a mini-app to Telegram?
When your mini-application is ready and tested, it’s time to add it to Telegram so that users can use it.
Step #1. Uploading the project to the server
The first step is to place your mini—application on the server. This is necessary in order for it to be available to users at any time. The server allows your application to run continuously and process requests in real time. Here’s how to do it:
Choose a hosting platform. This can be a free hosting service, for example, Heroku or Vercel, or a paid service like AWS or DigitalOcean. Choose the one that supports your development technology (for example, if you use JavaScript, select a server that supports Node.js ).
Upload your project to the server. You can place the project in a repository on GitHub or another similar service, and then connect it to the chosen hosting platform. This will allow you to deploy the application automatically with each update.
After downloading, your server will provide a link where your mini-application will be available online.
Step #2. Connecting the bot via a token
When the project is hosted on the server, the next step is to connect your bot so that Telegram can send requests to your application and receive responses. To do this, you will need the token that you received from BotFather when creating the bot.
Use this token in your server settings to link it to the Telegram API. This will allow your bot to interact with users via Telegram and forward all user requests to your server.
It is important that the server supports a secure connection (HTTPS), as Telegram requires this to ensure security.
Step number 3. API setup and application integration
In order for your mini-application to fully work inside Telegram, you need to properly configure the API and add elements that users can interact with.
Configuring the webhook
A webhook is a special URL to which Telegram will send all messages and commands from users of your bot. You will need to set up this URL on the server so that Telegram can direct requests directly to your application.
Setting up buttons and commands
To make it easy for users to launch and use your mini-app, add intuitive buttons and commands. For example, these may be the “Launch”, “Open” or other buttons that correspond to the functionality of your application. These buttons will allow users to interact with your mini-application directly in a chat with a bot, without having to enter text commands.
Set up commands that will activate certain actions in your application, such as launching a game or calling for help.
Processing commands and actions
It is important that your application responds correctly to user actions. When the user clicks a button or enters a command, the bot must send an appropriate response or activate the desired function of the mini-application. This ensures smooth and convenient user interaction with your application.
Step #4. Testing and launch
When everything is set up, it’s time to test your mini-application:
Make sure that the server is working correctly and is available online via HTTPS.
Log in to Telegram and open your bot. Click on the buttons that you have configured and make sure that the application works as you expected.
Make sure that the bot responds correctly to commands and interacts with the application.
If everything is configured correctly, your mini-application will be completely ready and available to all Telegram users. You will be able to monitor how users interact with the app and add new features and capabilities.
