Retail Price Sync Automation for Shopify & WooCommerce

Prerequisites

Before implementing this workflow, ensure you have the following:

• n8n account (required)
• Shopify store with API access (Admin API Access Token)
• WooCommerce store with REST API credentials (Consumer Key & Secret)
• Google account with access to:
  • Google Sheets (for logging)
  • Gmail (for notifications)
• Basic understanding of API integrations and workflow automation in n8n

---

This workflow automates the synchronization of product prices across Shopify and WooCommerce platforms to ensure retail consistency. It triggers when a price change is detected in either system, applies platform-specific pricing rules (such as psychological rounding) and updates the secondary platform. The workflow also includes a threshold-based alerting system via Gmail for major price drops and logs every change to a Google Sheets master file for auditing.

Quick Implementation Steps

1. Set the priceChangeThreshold in the Shopify Configuration and WooCommerce Configuration nodes.
2. Connect your Shopify Access Token credentials to the Shopify trigger and update nodes.
3. Connect your WooCommerce API credentials to the WooCommerce trigger and update nodes.
4. Link your Google Sheets OAuth2 and Gmail OAuth2 credentials for logging and notifications.
5. Specify the documentId for your pricing log in the Log Price Changes node.

What It Does

This workflow acts as a bridge between two major e-commerce platforms, ensuring that a price update in one is intelligently reflected in the other. It goes beyond simple mirroring by:

1. Threshold Monitoring: Detecting if a price change exceeds a set limit (e.g., $150 or $500) to trigger immediate management alerts.
2. Platform-Specific Logic: Automatically formatting prices for different environments—for example, rounding WooCommerce prices to the nearest .99 for psychological pricing while using standard rounding for Shopify.
3. Audit Trail Creation: Maintaining a centralized record of all price migrations in Google Sheets, including SKUs, old vs. new prices and timestamps.
4. Team Communication: Sending automated email notifications to ensure the team is aware of successful syncs or critical price volatility.

Who’s It For

• Multi-Channel Retailers who need to keep pricing in sync across Shopify and WooCommerce storefronts.
• Inventory Managers looking to automate price adjustments without manual data entry.
• Finance & Operations Teams requiring an automated audit log of all pricing modifications.

Technical Workflow Breakdown

Entry Points (Triggers)

1. Shopify Price Update: Triggers on the orders/updated topic (or product updates) to capture new price data from Shopify.
2. WooCommerce Price Update: Triggers on product.updated to capture changes originating from the WooCommerce store.

Processing & Logic

1. Configuration Nodes: Define the source system and set the specific threshold for what constitutes a "major" price change.
2. Apply Platform-Specific Rules: A custom code block that calculates psychological pricing (e.g., forcing a .99 ending) and ensures prices never drop below a minimum safety floor (e.g., $1.00).
3. Check Price Change Threshold: An internal filter that routes the workflow based on the magnitude of the price shift.

Output & Integrations

1. Update Nodes: Pushes the formatted price data to the target platform (Shopify or WooCommerce).
2. Log Price Changes: Appends a new row to a Google Sheet with detailed metadata.
3. Notifications: Uses Gmail to send high-priority alerts for major drops and routine confirmations for successful syncs.

Customization

Adjust Pricing Strategy

Modify the Apply Platform-Specific Rules (Code Node) to change rounding logic, add currency conversion factors or implement different psychological pricing tiers.

Change Alert Thresholds

Update the priceChangeThreshold value in the Shopify Configuration or WooCommerce Configuration nodes to make alerts more or less sensitive.

Expand Logging

The Log Price Changes node is set to autoMapInputData. You can add custom columns to your Google Sheet and the workflow will automatically attempt to fill them if the data exists in the workflow.

Troubleshooting Guide

Issue	Possible Cause	Solution
Sync Not Triggering	Webhook not registered correctly.	Check the webhookId in the Shopify/WooCommerce trigger nodes and ensure the apps have permission to send events.
Google Sheets Error	Sheet ID or Column names mismatched.	Verify the documentId and ensure the id column exists in your Sheet for matching.
Prices Not Rounding Correct/Expected	Code node logic error.	Review the JavaScript in Apply Platform-Specific Rules to ensure the Math functions match your strategy.
Emails Not Sending	Gmail OAuth2 expired.	Re-authenticate your Gmail credentials in the n8n settings.
