To better understand how marketplaces like Amazon work, let’s take a simple example: Imagine you're looking at a store window. A T-shirt catches your eye. You enter the store, head to the relevant section, and find the T-shirt available in various sizes, colors, and prices. These different options are what we call offers. Product vs Offer On marketplaces, the principle is similar: The product refers to the main listing: images, description, features. The offer rePopularValidate your catalog structure
It is essential to apply a consistent methodology when creating your products: defining references, assigning EAN codes, etc. This ensures a well-structured catalog for both internal use and external platforms such as marketplaces. On Amazon, the Reference field in PrestaShop is used as the SKU (unique internal identifier). This field is necessary to identify your offers and import orders. ⚠️ If the Reference field is empty, incorrect, or used multiple times in your catalog, syPopularUnderstanding logging
The Amazon module for PrestaShop uses an internal logging system. Each time a product is updated (price, stock, description, etc.), an event is recorded in the database when you click Save. These updates are then processed during the next export to Amazon.
