Run an assistant workflow: Google Sheets + vector search

Fires the moment a webhook arrives across Google Sheets, Slack and Gmail, looks the answer up in a vector store, then hands the decision to an AI agent. Built for task automation, around a "Stamp & Shape Request" step, in 23 documented nodes.

Run an assistant workflow with Gmail. An original, ready-to-import n8n workflow built around the 'AI Agent' pattern for AI & automation. It fires on a webhook and orchestrates 23 nodes across Google Sheets, Slack, HTTP / REST API. 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. Your team sees the right data at the right time.

Key benefits

  • Keeps Google Sheets and Slack in step for task automation, without anyone re-typing a row
  • A failed Google Sheets or Slack call is retried rather than dropped, at any of the 23 nodes in this task-automation build
  • The task-automation AI step is isolated from Google Sheets, so models swap without touching the other 23 nodes
  • Fans the same result out to Gmail in the same run, for task automation
  • Task-automation answers come from your indexed content, not model recall, before reaching Google Sheets

Use cases

  • Teams keeping Google Sheets and Slack aligned by hand for task automation
  • Answering task-automation questions from your own indexed documents, then replying in Google Sheets
  • Task automation work that needs a judgement call per item before it reaches Google Sheets
  • Pushing task-automation 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 Pinecone

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

Production level

Production-grade: idempotency, dead-letter handling, and reconciliation included.

  • 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, HTTP / REST API, 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.
