Automate an assistant workflow: Google Sheets, Slack & Gmail

Fires the moment a webhook arrives across Google Sheets, Slack and Gmail, hands the decision to an AI agent with its own tools, then drops anything it has already handled. Built for task automation, around a "Normalize Request Payload" step, in 22 documented nodes.

Automate 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 22 nodes across Google Sheets, Slack, Gmail. 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
  • Safe to re-run: records already in Google Sheets or Slack are skipped, across all 22 nodes of this task-automation build
  • A failed Google Sheets or Slack call is retried rather than dropped, at any of the 22 nodes in this task-automation build
  • Every task-automation run leaves an audit row behind, alongside Google Sheets
  • The task-automation AI step is isolated from Google Sheets, so models swap without touching the other 22 nodes

Use cases

  • Teams keeping Google Sheets and Slack aligned by hand for task automation
  • 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
  • Task automation work where "Normalize Request Payload" is still a manual step before Google Sheets

Agent tools included (2)

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.

  • Draft Specialist (Sub-workflow) · Another n8n workflow
  • Research Specialist (Sub-workflow) · Another n8n workflow

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.

  • Wiring an AI Agent to a chat model and a set of tools
  • Writing a system message that controls when the agent reaches for each tool
  • Giving a model a structured output parser so downstream nodes get clean fields

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, 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.
