Google Customer Reviews Opt-in Integration for OpenCart makes it easy to connect your OpenCart checkout with the Google Customer Reviews program.

The extension automatically displays the Google Customer Reviews survey opt-in after a customer successfully completes an order and sends the required order information to Google.

It provides a simple way for OpenCart merchants to collect genuine post-purchase customer feedback without manually adding or maintaining Google integration code.

Supports OpenCart 3 and OpenCart 4. Separate compatible releases are provided for each OpenCart version.

Problem Statement

Customer reviews are an important trust signal for online stores, but collecting genuine post-purchase feedback consistently can be difficult.

Google Customer Reviews provides a structured way to request feedback from customers who have completed a purchase, but manually integrating the required Google opt-in code with OpenCart requires order-specific information such as the customer's email, order ID, delivery country, and estimated delivery date.

This extension handles that OpenCart integration automatically.

There is no need to manually modify checkout templates or dynamically build the Google Customer Reviews integration for every completed order.

Who Is This Extension For?

This OpenCart extension is suitable for:

• OpenCart stores using Google Merchant Center.
• Merchants wanting to participate in Google Customer Reviews.
• Stores looking to collect more genuine post-purchase customer feedback.
• Businesses wanting to strengthen their Google store rating.
• OpenCart merchants who do not want to manually integrate Google's survey opt-in code.
• Multi-store OpenCart installations requiring separate Google Customer Reviews configuration.
• Existing OpenCart 3 stores as well as stores running OpenCart 4.

• Suitable for Multi-Store OpenCart Websites

Purpose of the Extension

The purpose of this extension is to provide a reliable bridge between OpenCart and Google Customer Reviews.

Instead of manually implementing Google's integration and retrieving order information through custom development, the extension automatically prepares the required information when an order is completed.

Customers are then given the option to participate in Google Customer Reviews directly from the OpenCart checkout success page.

This helps OpenCart merchants make customer feedback collection part of their normal post-purchase process without adding extra work for store administrators.
