Manage engineering change requests via webhooks and Slack approvals

⚙️ Manage Engineering Change Requests (ECR) via Slack

📋 Overview

Streamline your engineering change management process by integrating generic webhooks with Slack interactive approvals. This workflow receives a generic design change request, categorizes its impact level, and routes it to a Slack channel for approval.

This template is ideal for Mechanical Engineering teams, Manufacturing, and Project Managers who need to track drawing changes (ECR/ECO) without complex PLM software.

🚀 How it works

1. Receive Request: Catches a POST webhook containing drawing_no and change_reason.
2. Validation & Logic: Ensures data integrity and determines the "Impact Level" (High, Medium, Low) based on keywords in the reason (e.g., "Dimension" triggers specific logic).
3. Notification: Sends a formatted message to a designated Slack channel with a link to an approval form.
4. Human in the Loop: The workflow waits (pauses) until a reviewer approves or rejects the request via the n8n form.
5. Final Notification: Posts the final decision back to Slack.

🛠️ Setup Steps

1. Configure Webhook: Use the production URL of the Webhook node in your upstream application (e.g., Google Forms, internal tools, or Typeform).
2. Connect Slack: Select your Slack credential and choose the channel where approval requests should be sent in the Notify Slack nodes.
3. Customize Logic: Open the Switch node to adjust the keywords (e.g., "Material", "Dimension") that determine the impact level according to your company's policy.

💡 Requirements

• n8n (Self-hosted or Cloud)
