n8n Telegram Support Triage with Groq + Google Sheets

Turn Telegram crypto support messages into fast, risk-aware automation—using n8n, Groq, and Google Sheets

This n8n workflow triages incoming Telegram support messages (voice or text) for a crypto wallet. It transcribes voice with Groq Whisper, classifies intent and security risk with Groq Llama, escalates high-risk or frustrated users to a human agent with a holding voice reply, and logs everything to Google Sheets with Slack error alerts.

What this workflow does

• Triggers on new Telegram messages and checks whether the message contains voice, text, or an unsupported type.
• Transcribes input: downloads voice notes from Telegram and transcribes them using Groq Whisper; for text messages, it uses the message text as the transcript.
• Classifies using Groq: sends the transcript to Groq Chat Completions to determine intent, sentiment, and security risk, then parses the model’s JSON output.
• Prevents duplicate escalations: looks up the sender’s chatId in Google Sheets (“Escalations” tab) and enforces a 30-minute escalation lock.
• Escalates when needed: if locked, sends a holding message; otherwise, updates Google Sheets, notifies a human agent in Telegram, and sends the user a Groq-generated TTS voice reply for angry/frustrated or security-risk cases.
• Responds for non-escalated users: routes by intent and generates FAQ, Transaction/KYC, or Security/Trading replies using Groq Llama models, then sends them back in Telegram.
• Logs outcomes and failures: appends interactions to “Interactions”; on API failure, posts alerts to Slack, logs to “Errors”, and sends a fallback response.

Use cases

• Automated Telegram support for a crypto wallet with voice-note handling.
• Security-risk triage that escalates suspicious messages to a human agent.
• Reducing repeated escalations with a 30-minute lock per chatId.
• Ops visibility via Google Sheets logs and Slack error alerts.
