Amazon Mapping Wizard
The Amazon Mapping Wizard can be configured to automatically load your product catalog on Amazon, and can be set to run every time that a new Amazon Feed gets executed on the Scheduler.
Requirements
To list products on Amazon automatically, your products need to have UPC codes, or you need a UPC exemption with Amazon. UPC exemptions are only handed to merchants who have their own Brand that they have registered with Amazon.
You will also need to define a Default Item Type which can be set in the Amazon Rules section. The Item Type does not need to be accurate when listing products with UPC codes that are listed by other sellers on Amazon, but it is required to upload.
