Route documents: Slack for approvals

Starts when someone submits the form across Slack, Google Sheets and Airtable, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for approvals, around a "Prepare Approval Packet" step, in 22 documented nodes.

Route documents with Outlook and Airtable hands-free. An original, ready-to-import n8n workflow built around the 'Approval Workflow' pattern for software development & devops. It starts from a form and orchestrates 22 nodes across Slack, Google Sheets, Airtable. 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 Slack and Google Sheets in step for approvals, without anyone re-typing a row
  • Safe to re-run: records already in Slack or Google Sheets are skipped, across all 22 nodes of this approvals build
  • A failed Slack or Google Sheets call is retried rather than dropped, at any of the 22 nodes in this approvals build
  • Bad input stops the run for approvals instead of landing in Slack
  • Branches rejoin before Slack, so a approvals run reports once rather than 22 times

Use cases

  • Teams keeping Slack and Google Sheets aligned by hand for approvals
  • Approvals sequences that run over days and must survive a restart before Slack
  • Intake checked for completeness before it is stored in Slack, for approvals
  • Approvals work where "Prepare Approval Packet" is still a manual step before Slack

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.

  • Pausing a workflow on a Wait node until a human decides
  • Embedding a resume URL so approving is one click
  • Branching cleanly on approve versus decline

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 (Slack, Google Sheets, Airtable, Outlook, …). 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.
