Bot API 10.0

Today's update reshapes how bots communicate on Telegram – unlocking cooperative multi-bot agentic flows, seamless integration in any chat, granular access controls and more.

Guest Mode and Agentic Flows
• Introduced guest mode, allowing bots to easily participate in any chat without joining it.
• Users can summon up to 3 guest bots per message – unlocking complex agentic flows in any chat. Guest bots receive only relevant messages and can inspect caller context or send replies.
• Bots can now message each other by username if they enable bot-to-bot communication.
• Account automation via Business Bots no longer requires a Premium subscription.
• Business Bots can now interact with other bots on behalf of the user.

Chat Management
• Admin bots can now remove individual message reactions, clear all recent reactions from a user or restrict them from issuing more.
• The list of chat admins can now optionally return bot administrators.

Live Photos
• Introduced support for live photos – images enhanced with short built-in motion and sound.
• Bots can now detect, download and send live photos to any chat, including as paid media.

Polls
• Bots can now detect and attach media in both polls and individual poll options.
• Polls can now be limited to existing chat members or voters from specific countries.

General
• Users can now set a granular access whitelist for their bot via @BotFather, while Manager Bots can set one via the API.
• Bots can now fetch recent messages from the channel pinned to a user's profile.

• And more, see the full changelog for details:
