Merchant API Google WooCommerce

Google Merchant API for WooCommerce – Google Merchant Center Integration

How to connect WooCommerce with Google Merchant Center and automatically synchronize your products?

The Google Merchant API module integrates your WooCommerce store with Google Merchant Center and automates the process of sending product data to Google Shopping.

Products, prices, promotions, images and stock availability can be synchronized without manually preparing and uploading XML files. The module also supports variable products, making it suitable for stores with large and complex product catalogs.

Automatic WooCommerce Synchronization with Google Merchant Center

The module synchronizes products from WooCommerce with Google Merchant Center. Depending on the configuration, synchronization may include:

• product name,
• product description,
• product URL,
• product images,
• regular price,
• sale price,
• product availability,
• GTIN / EAN,
• MPN,
• brand,
• Google Product Category,
• product attributes.

Changes made in the store can then be automatically transferred to Google according to the configured synchronization schedule.

Google Shopping Without Manual XML Feed Management

Traditional WooCommerce integration with Google Merchant Center often requires preparing a product feed and periodically updating it.

Google Merchant API allows product data to be sent directly through the API. This makes it possible to automate synchronization and reduce the amount of manual work required from the store administrator.

Automatic Price and Stock Synchronization

The module synchronizes product availability and pricing information. Supported availability statuses include:

• in stock,
• available on backorder,
• out of stock.

Synchronization also includes regular and sale prices.

WooCommerce Variable Products in Google Shopping

The module supports products with variations such as color, size, material or other attributes.

Variations are properly grouped in Google using item_group_id. Each variation can be submitted to Google with its own SKU, price, availability and image.

This makes the solution suitable for stores with large numbers of variable products.

Synchronization of Promotions and Sale Prices

When a WooCommerce product has an active sale price, the module can send both the regular and sale price to Google, together with information about the promotion end date.

This helps maintain consistent pricing information between your WooCommerce store and the data submitted to Google Merchant Center.

Automatic Synchronization with Cron

Synchronization can be launched automatically using a Cron job. Available schedules include:

• every 15 minutes,
• every hour,
• every 2 hours,
• every 6 hours,
• once a day.

Products waiting for synchronization are processed according to the configured schedule.

Synchronization of Large Product Catalogs

The module includes an AJAX Batch Sync mechanism that divides large synchronization operations into smaller batches.

This makes it possible to synchronize hundreds or thousands of products without relying on a single large operation that could exceed browser execution limits.

The synchronization panel displays the progress of the operation, processed products and errors. Interrupted operations can be resumed.

Filtering Products Sent to Google Shopping

Not every product in your store has to be synchronized with Google Merchant Center. The module allows you to limit synchronization to selected products or product groups.

Products can be filtered by:

• category,
• manufacturer,
• price,
• stock availability,
• active status.

Individual products can also be excluded from synchronization directly from the product editing screen.

WooCommerce to Google Merchant Center Data Mapping

The module allows WooCommerce product data to be mapped to fields used by Google Merchant Center.

Supported data includes:

• product title,
• product description,
• product link,
• main and additional images,
• price,
• sale price,
• availability,
• GTIN / EAN,
• MPN,
• brand,
• Google Product Category,
• product type,
• color,
• age group,
• gender.

Custom Labels for Google Shopping and Google Ads

The module supports Custom Label 0–4, which can be used to add additional product classifications in Google Merchant Center.

This makes it easier to organize your product catalog and build more precise product campaign structures in Google Ads.

Automatic Google Product Category Mapping

The module allows products to be assigned to Google Product Category. Category mapping helps prepare product data for submission to Google Merchant Center.

WooCommerce Administration Panel

Synchronization settings and controls are available directly from the WooCommerce administration panel.

The panel allows you to:

• start synchronization manually,
• synchronize selected products,
• synchronize the entire catalog,
• view the number of synchronized products,
• check synchronization errors,
• monitor products waiting for synchronization.

Google Merchant API Error Logs and Diagnostics

Each synchronization operation can be recorded in the system logs. The administrator can check the operation status, number of processed products and information about errors returned by Google.

Logs make it easier to identify a specific product or field causing a problem during data submission to Google.

The log history can be exported to CSV, while older entries can be automatically removed.

Test Mode Before Starting Synchronization

The module includes a test mode that allows you to verify the configuration without actually sending product data to Google.

Operations are simulated and recorded in the logs, allowing you to verify the configuration before starting production synchronization.

Debug Mode for Administrators and Developers

Advanced debug mode records detailed information about communication with the Google Merchant API, including request data, JSON structures and API responses.

This feature can be particularly useful when diagnosing configuration problems or synchronization issues related to specific products.

Service Account and Google Authorization

The module supports the appropriate authorization method for connecting your store with Google services. A Service Account allows the integration to be configured for automated background synchronization processes.

Google Merchant API Instead of a Traditional XML Feed

Using the API allows product data to be transferred directly between WooCommerce and Google Merchant Center without relying on a traditional XML file as the primary synchronization method.

The main advantages of this integration include:

• automated product data submission,
• price and stock updates,
• support for individual products and larger batches,
• detailed synchronization error information,
• queued synchronization operations,
• support for large product catalogs.

Who Is the Google Merchant API Module For?

Google Merchant API is particularly useful for WooCommerce stores that use Google Merchant Center and Google Shopping and need to regularly update their product catalog.

The solution is especially suitable for stores:

• with large product catalogs,
• with variable products,
• with frequently changing prices,
• running regular promotions,
• with frequently changing stock levels,
• running Google Ads Shopping campaigns.

Technical Requirements

• WooCommerce
• PHP 7.0 or newer
• active Google Merchant Center account
• Google Cloud Console project with Merchant API enabled
• access to the WooCommerce administration panel

Installation and Configuration

The module is supplied with the required libraries. After installation, you need to configure the connection with Google Merchant Center and the required authentication credentials.

Configuration includes creating a project in Google Cloud Console, enabling access to the Merchant API and connecting the module with your Google Merchant Center account.

The module also includes a connection test that allows you to verify the configuration before starting synchronization.

Security and Performance

Authentication credentials are stored in the WooCommerce database. Batch synchronization and queue mechanisms help control the number of operations performed simultaneously and make it easier to process larger product catalogs.
