Telegram Mini Apps really are a powerful feature with the Telegram platform that enable developers to construct seamless, interactive web applications that run inside Telegram interface. These apps give a smooth consumer experience and can range between games and productivity tools to e-commerce storefronts and booking systems.

In this short article, we’ll walk you through the whole process of how to create telegram mini app over completely 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 internet technologies (HTML, CSS, JavaScript) and connect to 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 starting out, you’ll need:

A Telegram account

A Telegram bot (via BotFather)

Basic website design knowledge (HTML, CSS, JS)

Hosting on your web app (e.g., Vercel, Netlify, or your individual 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 create a new bot.

Choose a reputation and a username on your bot.

Copy the API token provided — you’ll want it to communicate with Telegram’s servers.

?? Step 2: Build the Web App
You may use plain HTML/CSS/JS or a frontend framework. Here’s a fairly easy example using plain HTML:

html
??????????
?????????????

Hello from Telegram Mini App!

Send Data




Host this file using any static hosting provider.

?? Step 3: Set Up Web App in Bot
Go back to BotFather.

Use /setdomain to join up your web app domain.

Use /setcommands to add 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
??????????
?????????????
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
??????????
?????????????
console.log(Telegram.WebApp.initDataUnsafe.user);
Make sure to validate this data on the 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 method 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 internet 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:

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 using the flexibility of internet technologies, developers can build powerful experiences inside chat interface.
