Extended Properties for listings

Extended Properties on listings are used to define the product specifications on a SKU level and add these details to listing templates. While the stock item itself keeps basic information (description, image, title), Extended Properties allow adding item details like item condition, brand, model, material, shipping prices, variation attributes like size, colour, etc.

Adding Extended Properties

To map Extended Properties on configurators, they must first be added to your inventory items. Extended Properties can be added in bulk via an inventory import (see this guide) or one-by-one in the Extended Properties tab in Product details (see steps here).

Mapping Extended Properties

When the necessary Extended Properties are added to your items, you can map them to different parts of the configurator. The options available depend on the channel. For full details on each channel configurator, please see the respective documentation from this list.

Mainly, Extended Properties are used for adding attributes/specifications to listings. This can be done in the Attributes section of a configurator (Specifications section on an eBay configurator).


 In the Attributes/Specifications screen, you can see two fields for each available attribute: Extended Property and Default Value.

  • Extended Property column: retrieves the attribute/specification from the item Extended Properties specified in the column. It will override the default value for this attribute if an Extended Property is present on the item.
  • Default Value column: sets a default value for the attribute/specification for all items listed using this configurator which do not have the mapped Extended Property added.

To map your needed Extended Property to an attribute, select the Extended Property name from the dropdown of the Extended Property column.

If you would also like to add Default Values, please check the specifics and examples given here on working with both options at once.

Updating the listing

When your Extended Properties have been mapped, then any new listing templates created with the configurator will automatically pull the data from the needed properties when the template is created.

If you need to add new attributes to existing listings or apply Extended Property mapping to existing listings, then the listings will need to be revised. There are several ways for updating existing listings depending on which templates need to be updated at once. Check the detailed Revising listings guide to apply the option which suits best with the specifics of your update.
