Telegram Bot API 10.4 – New Features and Improvements
- Mini-Websites Inside Chats (HTML Widgets): Bots can now send live, interactive widgets such as live price tickers, vote in interactive polls, or play simple games directly inside message bubbles, and the best part is that it now removes the need to open the link via an external browser.
Any Telegram message can now become an app.

- With this feature, the bot can update the shared data in one place, and the changes will then be reflected across all messages displaying that widget as they refresh, but the widgets currently work only in one-on-one private chats with bots.
- In this latest update, the new widgets can also interact with Telegram’s built-in TON wallet, allowing users to make payments or sign data when requested by a bot. When a widget makes such a request, a separate wallet window will appear for users to review and approve the same.
- The latest update also expands support for ephemeral responses, allowing bots to send private replies when users tap on their buttons in group chats. These replies will be visible only to the user who tapped the button and the bot, and thereby keep personal bot interactions from appearing to everyone else in the group.
- You can also now give Custom Bot Usernames such as @yourname_ai, @yourname_agent, @yourname_app, or @yourname_game, but for this you will need to have the Telegram Premium subscription.
