This guide explains how to build a create telegram mini app , from setup to deployment.

?? What Is a Telegram Mini App?
A Telegram Mini App is often a web app (built using HTML, CSS, and JavaScript) that launches inside Telegram by way of a bot. It runs within Telegram’s interface, offering rich UI, smooth interactions, and optional payment support — all without requiring users to go away the app or install anything.



?? What Can You Build?
You can use Mini Apps to generate:

?? E-commerce stores

??? Booking and scheduling apps

?? Dashboards and calculators

?? Mini games

?? Surveys and forms

?? Bill payment tools

? Step-by-Step: How to Build a Telegram Mini App
Step 1: Set Up Your Bot
Open Telegram and look for @BotFather

Use the command /start

Create a brand new bot with /newbot

Give it a title and a username (must end in bot)

Copy your API token — you’ll want it for backend interaction

Step 2: Build Your Web App
Telegram Mini Apps are regular web apps that must definitely be:

Responsive and mobile-first

Hosted with Hyper Text Transfer Protocol Secure

Written in HTML, CSS, JavaScript

Integrated with Telegram’s Web App API

Here’s a fairly easy example:

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

Hello from Telegram Mini App!

Get Telegram Info

Step 3: Host Your Mini App
Use any Hyper Text Transfer Protocol Secure-supported host like Vercel, Netlify, Firebase, or maybe your own server

Your app have to be served over Hyper Text Transfer Protocol Secure to operate inside Telegram

Step 4: Connect Your Mini App towards the Bot
Go returning to @BotFather

Choose your bot ? /setdomain

Set the beds base domain of one's Mini App (e.g., myapp.example.com)

Then set the Web App URL using /setmenubutton or /setcommands

Example bot command:

bash
??????????
?????????????
/setcommands
start - Launch the mini app
Inside your bot’s backend, you may use the reply_markup parameter to incorporate a Web App button for the message.

Example using Python (with python-telegram-bot):

python
??????????
?????????????
from telegram import InlineKeyboardButton, InlineKeyboardMarkup, WebAppInfo

keyboard = [
[InlineKeyboardButton("Open App", web_app=WebAppInfo(url="myapp.example.com"))]
]

reply_markup = InlineKeyboardMarkup(keyboard)
bot.send_message(chat_id=chat_id, text="Click to spread out app", reply_markup=reply_markup)
Step 5: Optional – Add Payment Integration
Use Telegram’s Payments API if you need to:

Sell products

Accept donations

Enable checkout flows

Telegram supports providers like Stripe, Payme, and YooMoney. You must first register a provider with @BotFather using /setpayment.

?? Security Tips
Always validate Telegram’s user identity on your backend while using initData parameter

Use the initDataUnsafe only for non-sensitive actions

Never trust client-side data without verification

Telegram provides init data validation instructions here

? Final Notes
