• Categories: Amazon handles categories as "Product Types". To separate or group products relevant to the channel (same as categories do) you can use other characteristics such as tags or Attribute Sets. Once you have selected a product type that fits your product, the connector automatically lists the fields available to be filled and allows field mapping.
• Products and Variants: Amazon are called "Listing Items", and both concepts fuse together in this platform. That means that all Sales Layer fields merge before being sent to Amazon.
