Detect WooCommerce order fraud and send alerts to Slack

Description

WooCommerce Fraud Detection & Slack Alert Workflow

This workflow automatically monitors WooCommerce orders, evaluates them for fraud using multiple checks (address mismatch, high-value orders, suspicious emails, admin orders), calculates a fraud score and sends alerts to Slack when risk is detected.

Quick Implementation Steps

Import the workflow JSON into n8n
Configure WooCommerce API credentials
Set up Slack API credentials and channel
Adjust fraud rules (amount threshold, email regex, etc.)
Test with sample order data
Activate the workflow

What It Does

This workflow automates fraud detection for WooCommerce orders by applying multiple validation checks and assigning a fraud score. It starts with scheduled execution, fetches order data and prepares it for evaluation by extracting key details such as billing information, order value and customer email.

Once the data is prepared, the workflow applies a series of fraud detection rules. These include checking whether billing and shipping details mismatch, identifying high-value orders, detecting suspicious or disposable email addresses and verifying if the order was created by an admin. Each condition contributes to a fraud score based on predefined logic.

Finally, all signals are merged and a fraud score is calculated. If the score crosses the defined threshold, a detailed alert is sent to a Slack channel with complete order and risk information, enabling quick manual review and action.

Who’s It For

WooCommerce API credentials configured in n8n
Slack workspace with API credentials
Slack channel ID for sending alerts
Basic understanding of n8n nodes and workflows

How It Works & Set Up

Setup Instructions

Import the workflow JSON into your n8n workspace
Configure the Schedule Trigger node to define execution frequency
Set up the WooCommerce node:
Add API credentials
Ensure correct store URL
Modify orderId if needed

Configure Slack node:
Connect Slack API credentials
Select or update the target channel

Review Set nodes:
Ensure fields like email, total and address are correctly mapped

Validate IF conditions:
Status check (pending/processing)
Address mismatch logic
High-value threshold (default: 500)
Email regex for disposable domains

Review Code node logic:
Fraud score calculation rules
Adjust scoring weights if needed

Test the workflow:
Use sample order data
Verify Slack alert output

Activate the workflow for automatic execution

How To Customize Nodes

Check High Value (>500)**
Modify the threshold value to match your business needs

Detect Disposable Email**
Update regex pattern to include more domains

Calculate Fraud Score (Code Node)**
Adjust scoring logic:
if ($json.high_value_order) score += 3;

Fraud Threshold Check**
Change minimum score required to trigger alerts

Slack Message Node**
Customize alert message format and included fields

Add-ons (Enhancements)

Store fraud results in a database (MySQL, MongoDB, etc.)
Automatically cancel or hold suspicious orders via WooCommerce API
Send email alerts in addition to Slack notifications
Add IP geolocation checks for advanced fraud detection
Integrate with third-party fraud detection APIs
Add risk categorization (Low / Medium / High)

Use Case Examples

Detect high-value fraudulent orders before fulfillment
Identify mismatched shipping addresses for manual review
Flag orders using disposable or temporary email addresses
Monitor admin-created orders to reduce internal misuse risk
Real-time fraud alerts for operations teams via Slack

> There can be many more use cases depending on how you extend and customize this workflow.

Troubleshooting Guide

| Issue | Possible Cause | Solution |
| --------------------------- | ------------------------------------- | -------------------------------------------- |
| No orders fetched | Incorrect WooCommerce credentials | Verify API keys and store URL |
| Slack message not sent | Wrong Slack credentials or channel ID | Reconnect Slack and check channel |
| Fraud score always 0 | Conditions not triggering | Verify IF node logic and data mapping |
| Email detection not working | Regex not matching | Update regex pattern |
| Workflow not running | Schedule trigger not configured | Set interval correctly and activate workflow |
