I would like to propose an enhancement to the Telegram Bot Platform — a server-side broadcast (Pub/Sub) mechanism for bots, similar to the internal architecture already used by Telegram Channels.
🔹 Problem
Currently, bots can only send messages through sendMessage, which requires one API call per user.
For large-scale bots, this model causes:
Heavy load on the Bot API and developer servers
Strict rate limits
Delayed or incomplete message delivery
Poor scalability for broadcast-type bots (news, alerts, notifications, etc.)
🔹 Proposed Solution
Introduce a server-managed broadcast system where the bot can publish a message once, and Telegram’s infrastructure distributes it to all users who have opted in — similar to how channels deliver content.
This can be achieved using a Pub/Sub architecture:
The bot acts as a Publisher by calling a new endpoint like:
POST /bot<token>/sendBroadcast
with a payload containing the message and audience scope.
Telegram servers handle the Subscription layer — i.e., which users follow the bot or have opted in for broadcast messages.
Telegram’s backend manages message fan-out efficiently, instead of requiring the bot to issue one message per chat.
Server behavior:
Telegram queues and delivers the broadcast internally (same as channel updates), with built-in anti-spam checks, rate limiting, and opt-out tracking.
Optional API:
GET /bot<token>/broadcastStatus/<id> → returns delivery stats, failures, user engagement.
🔹 Benefits
Efficiency: A single publish action instead of N API calls drastically reduces API load and Instant and consistent delivery, identical to channel propagation
I meant a section within the bot itself that would perform the same function as a channel. For example, a "Broadcasts" section where users can see messages, so there would be no need to create a channel. But essentially, it would work like a channel.
This could be better from a user interface perspective.
