Run an assistant workflow with Google Sheets for conversational AI

Fires the moment a webhook arrives across Google Sheets, Slack and PostgreSQL, looks the answer up in a vector store, then hands the decision to an AI agent. Built for conversational AI, around a "Stamp & Shape Request" step, in 19 documented nodes.

Run an assistant workflow with Gmail for your team. An original, ready-to-import n8n workflow built around the 'AI Agent' pattern for AI & automation. It fires on a webhook and orchestrates 19 nodes across Google Sheets, Slack, PostgreSQL. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. What used to take a morning now runs on its own.

Key benefits

  • Keeps Google Sheets and Slack in step for conversational AI, without anyone re-typing a row
  • A failed Google Sheets or Slack call is retried rather than dropped, at any of the 19 nodes in this conversational-AI build
  • Every conversational-AI run leaves an audit row behind, alongside Google Sheets
  • The conversational-AI AI step is isolated from Google Sheets, so models swap without touching the other 19 nodes
  • Fans the same result out to PostgreSQL in the same run, for conversational AI

Use cases

  • Teams keeping Google Sheets and Slack aligned by hand for conversational AI
  • Answering conversational-AI questions from your own indexed documents, then replying in Google Sheets
  • Conversational AI work that needs a judgement call per item before it reaches Google Sheets
  • Pushing conversational-AI events into Google Sheets and Slack the moment they land, not on the next poll

Agent tools included (1)

An AI Agent is only as capable as the tools wired into it. These are read from the template's own graph — every one is a real node in the file you download.

  • Knowledge Base Retriever · Vector Store PGVector

This agent runs without conversation memory - each run starts from the incoming request.

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Moving data between Google Sheets, Gmail and Slack in a single run
  • Adding retries and an explicit error path to external calls
  • Testing against pinned sample data before connecting anything real

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Google Sheets, Slack, PostgreSQL, Gmail). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
