Can I update images and titles through Salestio?
Amazon is a catalog-based marketplace, which means that multiple merchants that sell the same item will share the listing page. Because of this, Amazon restricts the ability to edit the listing information. A listing can be updated with a new title and images only if it was created with Salestio.
To update an existing listing, run the Send to Amazon action on an item, and Salestio will apply new product information when possible.
