How to Create a Telegram Mini App: A Step-by-Step Guide
Blog Article
Telegram Mini Apps really are a powerful feature in the Telegram platform that enable developers to construct seamless, interactive web applications that run inside the Telegram interface. These apps give a smooth buyer experience and can range between games and productivity tools to e-commerce storefronts and booking systems.
In this informative article, we’ll walk you through the entire process of how to create mini apps from scratch.
???? What Is a Telegram Mini App?
Telegram Mini Apps are lightweight web apps launched inside Telegram chats via inline buttons or through bot commands. They are built using web related technologies (HTML, CSS, JavaScript) and communicate with Telegram’s Bot API and Web Apps API.
These apps:
Run in Telegram's built-in browser
Can access user data (with permission)
Integrate seamlessly with Telegram bots
Support payment and authorization flows
????️ Tools & Prerequisites
Before getting started, you’ll need:
A Telegram account
A Telegram bot (via BotFather)
Basic website design knowledge (HTML, CSS, JS)
Hosting for the web app (e.g., Vercel, Netlify, or your own server)
Optional tools:
Node.js (for backend logic)
Web frameworks like React or Vue
???? Step 1: Create a Telegram Bot
Open @BotFather on Telegram.
Use /newbot to make a new bot.
Choose a name and a username to your bot.
Copy the API token provided — you’ll need it to communicate with Telegram’s servers.
???? Step 2: Build the Web App
You are able to use plain HTML/CSS/JS or a frontend framework. Here’s a fairly easy example using plain HTML:
html
Копировать
Редактировать
copyright src="//telegram.org/js/telegram-web-app.js">
Hello from Telegram Mini App!
copyright>
const tg = window.Telegram.WebApp;
tg.expand(); // Makes the app take full screen
function sendData()
tg.sendData("Hello Telegram!");
Host this file using any static hosting provider.
⚙️ Step 3: Set Up Web App in Bot
Go returning to BotFather.
Use /setdomain to register your web app domain.
Use /setcommands to incorporate a command like /start or /open.
In your bot code, you’ll send a keyboard button with a web_app object:
Example in Node.js (using node-telegram-bot-api):
js
Копировать
Редактировать
const TelegramBot = require('node-telegram-bot-api');
const token = 'YOUR_BOT_TOKEN';
const bot = new TelegramBot(token, polling: true );
bot.onText(//start/, (msg) =>
bot.sendMessage(msg.chat.id, "Open the mini app:",
reply_markup:
keyboard: [[ text: "Open App", web_app: url: "//yourdomain.com/app" ]],
resize_keyboard: true,
one_time_keyboard: true,
);
);
✅ Optional: Get User Data
In your frontend, you have access to Telegram user info via Telegram.WebApp.initDataUnsafe.
js
Копировать
Редактировать
console.log(Telegram.WebApp.initDataUnsafe.user);
Make sure to validate this data in your backend using Telegram’s Web App Authorization.
???? Bonus: Accept Payments
Telegram Mini Apps support payments via Telegram’s payment system.
Set up a payment provider via BotFather (/setpaymentoptions).
Use the Bot API’s sendInvoice solution to create payment flows.
Payments are processed securely via Telegram with support for services like Stripe.
???? Testing Your Mini App
Use Telegram on mobile or desktop (not the web app).
Make sure your domain uses Hyper Text Transfer Protocol Secure.
Ensure your bot has access to web app features and commands.
???? Use Cases
Telegram Mini Apps can be used as:
E-commerce (stores, carts, checkouts)
Booking and reservations
Games and entertainment
Form submissions
Personal dashboards
Telegram Mini Apps bridge the gap between messaging and fully interactive applications. By combining the reach of Telegram bots while using flexibility of web technologies, developers can build powerful experiences in the chat interface. Report this page
