Order Processing with Google Sheets and Slack: Inventory Checks and Alerts

Overview

A cornerstone of your Order Management System, this workflow ensures seamless inventory control through fully automated stock checks, leading to a direct reduction in operational costs. It provides real-time alerts to the responsible personnel, enabling proactive issue detection and resolution to eliminate the financial damages associated with unexpected stock-outs.

How it works

Order Webhook

Receives orders from external sources (e.g., website, form, or app) via API.

Check Order Request

Checks the validity of the order (e.g., complete product, valid customer details)

Check Inventory

Retrieve inventory information and compare it with the order request.

Notifications

• Generate a notification to Slack for the manager indicating a successful order or an out-of-stock situation.

Logging

• Log the process details to a Google Sheet for tracking.

Set up steps

Webhook

• Create a JSON request with the following format to call the Webhook Url

{
  "id": "ORDER1001",
  "customer": {
    "name": "Customer",
    "email": "[email protected]"
  },
  "items": [
    {
      "sku": "SKU001",
      "quantity": 2,
      "name": "Product A",
      "price": 5000
    },
    {
      "sku": "SKU002",
      "quantity": 2,
      "name": "Product C",
      "price": 10000
    }
  ],
  "total": 30000
}

• Define the greater than or less than conditions on the inventory level to enter the corresponding branches.

Google Sheet

• Clone the file to your Google Drive. (WMS Data Demo)
• Replace your credentials and connect.
• Access permission must be granted to n8n.

Slack

• Replace your credentials and connect.
• A channel named "warehouse" needs to be prepared to receive notifications (if using a different name, you must update the Slack node).
