How to set up an integration between Digital Commerce and Google Shopping

Purpose and scope

This content is intended only for customers with an existing integration between Experlogix Digital Commerce and Google Shopping.

Read How do I configure and manage Google Merchant Center? for our updated integration process.

We recommend that if you have an existing integration, please update your integration using our new Google Merchant App before August 2026.

This is because Google will no longer support the Content API for Google Shopping from 18th August 2026; we had used this API to integrate Experlogix Digital Commerce and Google Shopping.

The integration between Digital Commerce and Google Shopping syncs your product catalogue with Google Merchant Center. Once synced, your store’s products can be included in Google’s free listings and promoted using Smart Shopping campaigns. Our built-in configuration tool guides you through creating a link between our software and Google Merchant Center, which allows you to use Google Shopping campaign ads with direct links to products in WebShop.

This feature guide explains in detail how to use our built-in configuration tool to integrate Experlogix Digital Commerce with Google Shopping.

This feature is only available as part of the Digital Marketing SmartPack. Contact our sales team for more information.
