A product data feed is a hierarchical list of your products and the information about them, crammed into a single file that can be read by another application. The information is in a specific order, so that the server it is sent to can parse that information correctly. Shoppingfeed fetches data from the app or module that you installed and updates itself regularly. This special feed, also known as the Source Feed, refreshes itself with the most up to date product and inventory data.
What is a field?
Data comes to Shoppingfeed through the source feed. Our app connected to your store is gathering that information and sending it back to our platform. That information is organized into a stacked tree of containers, all in a specific order. We call those containers fields. You can create fields that live in Shoppingfeed and serve to hold information on the Create New Fields page
What is a product variant?
When you sell the same product in different colors, sizes, etc, you are using variations. You can train Shoppingfeed to look into specific fields for those variation names using the Manage Colors & Sizes tool. All of your variation fields are collected into either one master color field or one master size field. These fields are named {autotag_color} and {autotag_size}, and can be found, and re-mapped in any channels' Field Mapping page.
