🧩 Building an AI Telegram Agent in n8n – Workflow Guide

Instead of sharing raw JSON, let’s go through a clear workflow scheme + step-by-step instructions. This makes it much easier for readers to understand and replicate.

🗂 AI Telegram Agent Workflow in n8n

[User in Telegram]  
        ⬇  
[Telegram Trigger Node] → receives the message  
        ⬇  
[AI Node (OpenAI / HuggingFace)] → processes text and generates a reply  
        ⬇  
[Telegram Send Message Node] → sends the response back to the user  

🔧 Step-by-Step Build in n8n

1️⃣ Create a Telegram Bot

• Open @BotFather in Telegram.
• Run /newbot to create a new bot.
• Copy the API Token – you’ll need it in n8n.

2️⃣ Set Up the Telegram Trigger

• In n8n, add a Telegram Trigger node.
• Paste your API Token.
• Choose the event: On New Message.
• Now every incoming Telegram message will start the workflow.

3️⃣ Add AI for Processing

• Insert an OpenAI (Chat) node or an HTTP Request node (for other AI APIs).

• In the Prompt field, pass the incoming Telegram message:

  {{$json["message"]}}  
  

• Configure the model (e.g., gpt-3.5-turbo).

4️⃣ Send the Reply Back to Telegram

• Add a Telegram → Send Message node.

• In the Chat ID field, map:

  {{$json["message"]["chat"]["id"]}}  
  

• In the Text field, insert the AI response:

  {{$json["choices"][0]["message"]["content"]}}  
  

5️⃣ Run & Test

• Save the workflow and click Activate.
• Send a message to your Telegram bot → you should get an AI-powered reply instantly.

📌 Final Workflow Structure

(1) Telegram Trigger
         ⬇
(2) OpenAI (or HTTP → AI API)
         ⬇
(3) Telegram Send Message

👉 This workflow can be extended further:

• Add filters for commands (/help, /start).
• Store chat history in Google Sheets.
• Push analytics to Grafana or Prometheus.

📌 Summary

n8n makes it easy to build AI-powered Telegram agents without heavy coding.
With just a few steps, you can automate Telegram interactions, integrate AI, and scale workflows for real-world use.
