The eCommerce Reviews API collects product and review data on an ad-hoc basis. The API includes access to product details data as well as corresponding reviews data. The data collected here is product based which means every review that is collected is correlated directly to a product that was collected. The other API we offer, the Reviews API is a repository based solution that provides its customers with a stream of reviews data – which are not specifically allocated to a product, but rather are accessed by querying the repository.
