Definition of product categories
The eBay marketplace defines mandatory characteristics for each item offered for sale.
Item details can include brand, size, type, colour, style or any other relevant information about the item you are selling. Item details are currently required in a number of categories on eBay, including Fashion, Home & Garden, Toys & Games, and Vehicle Parts & Accessories.
This page shows all the required item characteristics: https://www.ebay.com/sellercenter/listings/item-specifics-requirements
A category definition contains the category name and other information about the listings, especially the item characteristics.
To offer an item for sale, the characteristics required by eBay for this item must be specified in the PrestaShop product listing.
During the synchronisation of products between eBay and PrestaShop, the module checks for the presence of the required characteristics.
If features are missing during synchronisation, the product listing will not be published on eBay. The reason for the synchronization failure will be visible in the "Listings" section of the module, in the "Errors" tab.
Usually, the missing feature is specified.
After the first synchronisation of a PrestaShop product category, the eBay module creates a category definition that will be used for subsequent synchronisations.
Why update category definitions?
eBay periodically updates the list of mandatory features.
Similarly, merchants can also make changes to their product categories on PrestaShop by adding or removing product features.
For this reason, it is necessary to periodically update the category definitions.
How do I know if my category definitions are up to date?
You can ensure that the category definitions created are still compatible with the required object characteristics through the Category Definition Comparison Tool.
This is available in the "Settings" > "Tools" tab.
This button does not change the category definitions, it compares the definitions you are using with the definitions available on eBay. So you can use it as often as you like.
If there are any inconsistencies, you can use the "update category definitions" tool included in the module to update the existing definitions.
