Introduction

Every project or product manager knows this pain: decisions get made in Slack, approvals get buried in threads, and weeks later no one remembers who approved what. Scope changes, feature requests, and timeline adjustments end up scattered across tools with no clear audit trail.

In this guide, you’ll learn how to build a simple but powerful approval workflow using Make.com, Slack, and Notion. The result is a lightweight system that routes approvals automatically, captures decisions in real time, and creates a permanent record PMs can rely on.

What This Workflow Does

This automation allows you to:

• Submit approval requests from Notion
• Automatically notify the right stakeholder in Slack
• Approve or reject decisions directly from Slack
• Log every decision with timestamps in Notion
• Notify the requester instantly once a decision is made

It’s fast, transparent, and removes unnecessary follow-ups.

Tools You’ll Need

You only need three tools:

• Make.com for automation logic
• Notion as the approval request database and audit log
• Slack as the decision and approval interface

No advanced technical skills are required.
