Telegram Bot API: Getting Started Guide

The Telegram Bot API is one of the most developer-friendly APIs available. Whether you're building a customer service bot, notification system, or AI assistant, this guide walks you through everything from setup to deployment.

Step 1: Create Your Bot

1. Open Telegram and search for @BotFather
2. Send /newbot
3. Choose a display name (e.g., "My Awesome Bot")
4. Choose a username ending in "bot" (e.g., "my_awesome_bot")
5. Save the API token BotFather gives you

See our detailed BotFather guide for more.

Step 2: Send Your First Message

You need your Telegram User ID to send a message. Use this HTTP request:

GET https://api.telegram.org/bot<TOKEN>/sendMessage?chat_id=YOUR_ID&text=Hello!

Replace <TOKEN> with your bot token and YOUR_ID with your numeric User ID.

Step 3: Receive Messages (Webhooks vs Polling)

Long Polling (simple, good for development):

GET https://api.telegram.org/bot<TOKEN>/getUpdates

Webhooks (production-ready, real-time):

POST https://api.telegram.org/bot<TOKEN>/setWebhook
{"url": "https://your-server.com/webhook"}

Step 4: Handle Commands

Commands start with /. Common patterns:

• /start — First interaction, send welcome message
• /help — Show available commands
• /settings — User preferences

Key API Methods

• sendMessage — Send text (supports Markdown and HTML)
• sendPhoto/sendDocument — Send media files
• editMessageText — Update existing messages
• answerCallbackQuery — Respond to inline button presses
• getChatMember — Check user status in a group

Popular Libraries

• Python: python-telegram-bot, aiogram, Telethon
• JavaScript: node-telegram-bot-api, grammY, Telegraf
• Go: telebot, gotgbot
• Rust: teloxide

Security Best Practices

• Never expose your bot token in public repositories
• Validate user IDs before processing sensitive commands
• Use webhook secrets to verify requests come from Telegram
• Rate-limit user interactions to prevent abuse

Get your Telegram User ID with @userid_checkbot to start testing.
