Practical guide
Create an AI agent for Telegram by starting with its business job in Builder. Test the agent’s sources and actions, configure the supported Telegram connection and verify the actual conversation before sharing it.
Before you read
By the end, you have a published Prostir AI agent available at https://t.me/your_agent_bot. Telegram sends messages to Prostir through the registered HTTPS webhook, and the agent answers from its instructions, knowledge, tools, and model.
Anyone who wants to create an AI agent in Telegram without writing bot code, hosting a backend, or configuring Telegram webhooks by hand.

You need a browser for Prostir, the Telegram app, and your Prostir workspace.
Use the official Telegram app on desktop or mobile. Sign in to the Telegram account that should own the bot.
In Telegram search, type BotFather and open @BotFather. This is Telegram's official bot for creating and managing bots.
Send /newbot. BotFather asks for a display name first, then a username. The username must end in bot, for example your_agent_bot or YourAgentBot.
BotFather returns a token that looks like 123456:ABC... Treat it like a password: do not paste it into public docs, tickets, screenshots, or chats. If it is lost or leaked, use /token in BotFather to generate a new one.
Open Prostir in your browser, create an agent, write what it should do, add the knowledge or tools it needs, select the model, and publish when the agent is ready.
In Channels, select the Agent's explicit channel runtime model first: a saved BYOK connection or a Prostir-hosted model with positive Model Usage Credits. Turn on the agent-level Channels switch, choose Telegram, paste the BotFather token and username without @, then press Save. Prostir registers the webhook and enables Telegram only when publication, model, switch, credentials, and credit checks pass; otherwise the channel stays disabled with a visible error.
Open https://t.me/your_agent_bot, press Start, send a real question, and watch the conversation appear in Prostir. If the answer needs you, jump in from Channels as a human.
The setup is simple because the hard parts have a clear owner.
Browser, Telegram app, BotFather token, Save.
Browser, Telegram app, BotFather token, Save.
I created @YourAgentBot with BotFather in Telegram and copied the token. I want it connected to my support agent.
Create or open the agent in Prostir. Add the support instructions and knowledge first so the Telegram channel has something real to answer from.
The agent is ready. Where do I put the Telegram key?
Open Channels, select the explicit channel runtime model, confirm positive credits if it is hosted, and turn on the Agent's Channels switch. Then choose Telegram, paste the BotFather token, enter YourAgentBot as the bot username, and press Save.
ProstirTelegram settings saved. The webhook is registered and the channel is enabled only after the published-Agent, channel-model, Channels-switch, credential, and hosted-credit checks pass; otherwise it remains disabled with a visible error.
