Telegram Developer Guide: Build Bots, Integrations & Apps

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:

Talk to @BotFather and follow instructions to create a new bot.
Give your bot a name and username. @BotFather will generate an authorization token.
Save the token for later use in API requests.
Create a bot account on Telegram and start chatting with your bot.
Send API requests to https://api.telegram.org/bot{token}/{method} with your bot's token.
Process updates and handle events using a webhooks or polling.
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.
