Since Shopper Approved uses the Google feed data format, you will need to install and enable the Google Product Feed add-on and generate a data feed using it.
To generate data feed, use the "Generate a feed and sync the settings" link on any Product Review add-on related page in your store's Admin area:
The add-on settings page
Product and Category pages
Merchant Review Survey page
The data feed will be automatically imported to Shopper Approved, and you will be able to find a link to it in the Dashboard -> Product -> Integration section at ShopperApproved.
Once the Google data feed has been submitted to ShopperApproved, your product reviews should become available in the ShopperApproved dashboard, where you will be able to manage them further.
The reviews will be updated automatically every time you re-generate the Google feed in X-Cart.
Provided a customer survey has been enabled in the add-on settings, your store will prompt your customers to provide feedback after placing an order. They will see a pop-up screen on the invoice page in the storefront, where they will rate their customer experience and answer the survey questions.
It is also possible to leave feedback on a product directly on the product details page in the storefront. For example, a buyer can use the Reviews tab of a product details page for the purpose:
All approved reviews are published in the Reviews tab of a related product details page.
