I Prompted ChatGPT: What's a Telegram Mini-App?

Response:

A Telegram Mini App is a lightweight, web-based application that can run within the Telegram app itself. They are built using JavaScript, HTML, and CSS, similar to traditional web apps, and are designed to offer a seamless, interactive experience without the need to leave Telegram. Mini Apps allow developers to integrate services like games, e-commerce, or tools directly into Telegram chats or channels.

They leverage Telegram's Bot API and Web Apps API, allowing developers to create highly interactive interfaces with minimal friction for the user.
