Telegram Claude Sonnet Chatbot n8n Workflow Automation

Turn your Telegram bot into a Claude-powered conversational assistant—automated with n8n

This n8n workflow listens for every new message your Telegram bot receives, sends the user’s text to Anthropic Claude (Sonnet 4.6) with short-term per-chat context, and then posts Claude’s reply back into the same Telegram chat automatically.

What this workflow does

• Triggers on new Telegram messages using the Telegram Trigger node.
• Extracts message text and chat ID from the Telegram update.
• Sends the message to an Anthropic Claude-powered AI Agent (via an n8n AI Agent using a friendly system prompt).
• Retains recent context per chat ID so conversations stay coherent within the same Telegram thread.
• Returns Claude’s response to the originating Telegram chat by sending the generated text back to the same chat.

Setup (quick and practical)

• Create a Telegram bot with BotFather and add your Telegram API credentials in the Telegram Trigger and Telegram nodes.
• Add an Anthropic (Claude) API credential and select Claude Sonnet 4.6 in the language model node.
• Activate the workflow and start a conversation with your bot in Telegram to begin receiving AI replies.

Use cases

• Provide instant Q&A support directly in Telegram for your SaaS or service.
• Answer user questions conversationally while preserving context for each Telegram chat.
• Prototype an AI assistant experience without building a separate chat backend—just Telegram + n8n + Claude.
