productlink is the full URL to the product page on your website. It’s used to convert each product description on Feefo into a clickable link back to your product page. The link greatly aids future conversion as prospective customers are taken directly from Feefo to your product page. If you don’t wish to link to individual product pages, the link can point to your home page or a page of your choice. If an invalid productlink value is supplied in a sale request it will be rejected and an error message will be displayed. See below an example as to how the productlink is used to link from a product review to the merchant's product web page.
