n8n Telegram Support Agent: Groq + Pinecone + Supabase + Slack

Turn Telegram support into a real, production-ready AI agent—backed by your knowledge base, live order data, and Slack escalation

RELAY is an n8n Telegram support agent that answers customers with verified information from your real data—using Groq for response drafting, Pinecone for knowledge search, and Supabase for chat memory, rate-limiting, and order lookups. If something can’t be resolved automatically, it escalates to Slack as a trackable ticket.

What this workflow does

• Receives new Telegram messages and checks Supabase to ignore duplicate Telegram updates.
• Enforces user rate-limiting via Supabase sliding-window counters, replying with a limit response when a user exceeds the message threshold.
• Builds conversation context by validating/normalizing incoming text and retrieving the last 10 messages from Supabase to format a conversation history.
• Drafts a structured support reply using a Groq chat model agent that can search a Pinecone vector knowledge base (with Google Gemini embeddings), look up orders in Supabase, and check for existing follow-up tickets.
• Approves before sending: extracts any order ID and email from the draft, fetches matching order records from Supabase, then sends the question/evidence/draft to a second Groq model to approve or revise the answer.
• Stores chat memory in Supabase and replies to the customer on Telegram.
• Escalates unresolved issues by creating a pending follow-up ticket in Supabase (only if none is already open) and posting escalation details to a Slack channel—while still replying on Telegram.

Use cases

• Instant Telegram FAQs powered by your Pinecone knowledge base (no guessing).
• Order status and support answers using live order data from Supabase.
• High-volume support handling with built-in rate-limiting and safe model approval.
• Seamless handoff to your team via Slack tickets when human follow-up is needed.
