Telegram Developer: A Comprehensive Guide

Published on October 25, 2023

Introduction to Telegram Bot API

The Telegram Bot API is a HTTP-based interface created for developers keen on building bots for Telegram. It allows developers to easily create bots that can communicate with Telegram users. The API uses Telegram's cloud service to handle most of the work, so developers don't have to worry about scaling, encryption and other complexities. Some key capabilities offered by the Telegram Bot API include:

  • Sending and receiving messages
  • Forwarding messages and media
  • Receiving updates and event notifications
  • Handling payments via Telegram Payments
  • Storing bot data on Telegram Cloud

The API uses a simple token-based authentication system. Each bot is issued a unique authentication token when created. All API requests must include this token. The API allows bots to handle text, media, stickers, invoices and other common Telegram entities.

Setting up Telegram Bot API

Here are the key steps to set up the Telegram Bot API for your bot:

  1. Talk to @BotFather and follow instructions to create a new bot.
  2. Give your bot a name and username. @BotFather will generate an authorization token.
  3. Save the token for later use in API requests.
  4. Create a bot account on Telegram and start chatting with your bot.
  5. Send API requests to{token}/{method} with your bot's token.
  6. Process updates and handle events using a webhooks or polling.
  7. Refer to the API documentation and code samples to build your bot's capabilities.

That covers the basics of getting set up with the Telegram Bot API. With the token and API endpoint, you are ready start building a fully-featured bot.

Creating bots with Telegram Bot API

The Telegram Bot API allows creating different types of bots with various capabilities:

  • Chatbots - For conversational bots that react to text messages
  • Payments bots - For handling payments via Telegram Payments
  • Games bots - For creating gaming experiences inside Telegram
  • Sticker bots - For uploading and distributing sticker packs
  • Moderation bots - Managing groups, filtering content, blocking spam

Key features of the API to build advanced Telegram bots include:

  • Sending media: photos, audio, documents, stickers
  • Message formatting: Markdown, HTML
  • Inline querying to display results directly in chat
  • Custom keyboards for interactive menus
  • Silent and group messaging

The Webhook mode allows bots to get real-time notifications on message events. For simple bots, the GetUpdates method can be polled periodically. The API has client libraries for most popular programming languages.

Integrating bots with external services

Telegram bots can be integrated with external services in several ways:

  • Use webhooks to connect bots to external APIs and process updates in real-time.
  • Make HTTP requests from bot code to external APIs to fetch data or post content.
  • Use a middleware layer to securely manage connections between bot and third-party services.
  • Implement Telegram Login to allow users to sign-in via their Telegram accounts.
  • Use Telegram Payments to accept payments from users that are processed by external payment providers.

Popular integrations include e-commerce platforms, content management systems, identity services, payment gateways, CRM software, support ticketing systems and IoT platforms. The Telegram Bot API supports generic webhooks that can connect with any external service with a public API and endpoint.

Telegram Bot API Libraries

Here are some popular open source Telegram Bot API libraries for various programming languages:

  • Python - python-telegram-bot, pyTelegramBotAPI
  • JavaScript - node-telegram-bot-api
  • Java - Telegrambots
  • C# -.NET Telegram Bot API
  • Ruby - telegram-bot-ruby
  • PHP - PHP Telegram Bot

These libraries provide wrappers and abstraction over the core Telegram Bot API. They make it easier to get started building bots by handling low level details like HTTP requests, serialization, WebSocket connections etc. Most libraries are well-maintained with detailed documentation and code samples to help new developers learn quickly.

Markdown Support for Telegram Bot Channel

Telegram supports Markdown-style formatting for text messages, which can be leveraged for Telegram bot channels. Here are some formatting features available:

  • Bold - **text**
  • Italic - _text_
  • Code - `text`
  • Preformatted - ```text```
  • Links - [text](url)

Markdown formatting allows creating text-style messages with Telegram bot channels. It helps present content in visually structured layouts and highlight important information for users.

Formatting Messages with Markdown Syntax

Here's an example of formatting a Telegram bot channel message using Markdown:**Today's News Briefing** _Politics_ President [Joe Biden]( signed a new climate change bill into law. ``This is a monumental step for U.S. climate policy,'' said the President. _Technology_   Facebook parent company [Meta]( announced second quarter earnings. Revenue was below expectations due to macroeconomic issues. Stay tuned for more updates throughout the day! This demonstrates using bold, italic, hyperlinks and code formatting to structure the message. The syntax helps highlight headings, entities, quotes and external links for readers.

Supported Markdown Syntax Options

In addition to basic styling, Telegram's Markdown syntax supports:

  • Lists - Ordered and unordered
  • Headings - H1 to H6 using #

Text messages can convey information, instructions, alerts etc. Choice messages allow collecting user feedback. Rich Cards present content in interactive, visually structured templates. The API has methods like sendMessage, sendPoll and sendMediaGroup to send these message types.

JSON Payload for Sending Text Messages

Here is an example JSON payload for sending a Markdown-formatted text message using the Telegram Bot API:{  "chat_id": "1234567",  "text": "**Today's News**\n\n_Top Headlines:_\n* Markets fall on new manufacturing numbers \n* Government announces economic stimulus",  "parse_mode": "Markdown" } It specifies the recipient chat, Markdown-formatted text content and parsing mode. The API method sendMessage can be used with this payload to broadcast the message. Similar payloads can be constructed to send choice or card-based interactive messages.

Formatting Text in Telegram

Telegram supports various formatting options to style text messages:

  • **Bold** - Asterisks around text
  • *Italic* - Underscores around text
