A Data Feed (also referred to as a Product Feed) is one of the key promotional materials for affiliates, which allows them to automatically display millions of products on their website. Affiliates will be provided with a fixed URL to download the Data Feed files from an Alibaba.com server. These Data Feed files are provided in XML format. It is important that affiliates include accurate information and keep the Data Feed up to date. Only a few selected business partners have access to using Data Feed by invite only.
