InventoryItem

availability

This container is used to specify the quantity of the inventory item that are available for purchase.

This container is optional up until the seller is ready to publish an offer with the SKU, at which time it becomes required. Availability data must also be passed if an inventory item is being updated and availability data already exists for that inventory item.

Since an inventory item must have specified quantity before being published in an offer, this container is always returned in the 'Get' calls for SKUs that are part of a published offer. If a SKU is not part of a published offer, this container will only be returned if set for the inventory item.

condition

This enumeration value indicates the condition of the item. Supported item condition values will vary by eBay site and category. To see which item condition values that a particular eBay category supports, use the getItemConditionPolicies method of the Metadata API. This method returns condition ID values that map to the enumeration values defined in the ConditionEnum type. The Item condition ID and name values topic in the Selling Integration Guide has a table that maps condition ID values to ConditionEnum values. The getItemConditionPolicies call reference page has more information.

A condition value is optional up until the seller is ready to publish an offer with the SKU, at which time it becomes required for most eBay categories.

Note: The 'Manufacturer Refurbished' item condition is no longer a valid item condition on any eBay marketplace, and to reflect this change, the MANUFACTURER_REFURBISHED value is no longer applicable, and should not be used. With Version 1.13.0, the CERTIFIED_REFURBISHED enumeration value has been introduced, and CR-eligible sellers should make a note to start using CERTIFIED_REFURBISHED from this point forward. For the time being, if the MANUFACTURER_REFURBISHED enum is used in a createOrReplaceInventoryItem method, it will be accepted but automatically converted by eBay to CERTIFIED_REFURBISHED. In the future, the MANUFACTURER_REFURBISHED may start triggering an error if used.

To list an item as 'Certified Refurbished', a seller must be pre-qualified by eBay for this feature. Any seller who is not eligible for this feature will be blocked if they try to create a new listing or revise an existing listing with this item condition.

Any seller that is interested in eligibility requirements to list with 'Certified Refurbished' should see the Certified refurbished program page in Seller Center.

conditionDescription

This string field is used by the seller to more clearly describe the condition of a used inventory item, or an inventory item whose condition value is not NEW, LIKE_NEW, NEW_OTHER, or NEW_WITH_DEFECTS.

The conditionDescription field is available for all eBay categories. If the conditionDescription field is used with an item in one of the new conditions (mentioned in previous paragraph), eBay will simply ignore this field if included, and eBay will return a warning message to the user.

This field should only be used to further clarify the condition of the used item. It should not be used for branding, promotions, shipping, returns, payment or other information unrelated to the condition of the used item. Make sure that the condition value, condition description, listing description, and the item's pictures do not contradict one another.

This field is not always required, but is required if an inventory item is being updated and a condition description already exists for that inventory item.

This field is returned in the getInventoryItem and getInventoryItems calls if a condition description was provided for a used inventory item.

Max Length: 1000.

conditionDescriptors

array of ConditionDescriptor

This container is used by the seller to provide additional information about the condition of an item in a structured format. Condition descriptors are name-value attributes that can be either closed set or open text inputs.

To retrieve all condition descriptor numeric IDs for a category, use the getItemConditionPolicies method of the Metadata API.

packageWeightAndSize

This container is used if the seller is offering one or more calculated shipping options for the inventory item, or if the seller is offering flat-rate shipping but is including a shipping surcharge based on the item's weight. This container is used to specify the dimensions and weight of a shipping package.

Note: Package weight and dimensions are only supported for the following marketplaces: AU, CA, DE, IT, UK, US, and Motors. If this information is provided on other marketplaces, it will be ignored.
This container is not always required, but is required if an inventory item is being updated and shipping package data already exists for that inventory item.

This container is returned in the getInventoryItem and getInventoryItems calls if package type, package weight, and/or package dimensions are specified for an inventory item.

See the Calculated shipping help page for more information on calculated shipping.

product

This container is used to define the product details, such as product title, product description, product identifiers (eBay Product ID, GTIN, or Brand/MPN pair), product aspects/item specifics, and product images. Note that an eBay Product ID (ePID) or a Global Trade Item Number (GTIN) value can be used in an attempt to find a matching product in the eBay Catalog. If a product match is found, the inventory item record will automatically pick up all product details associated with the eBay Catalog product.

Many eBay categories will require at least one product identifier (a GTIN or a Brand/MPN pair). To discover which product identifier(s) that an eBay category might require or support, use the getItemAspectsForCategory method in the Taxonomy API. In the getItemAspectsForCategory response, look for product identifier names (brand, mpn, upc, ean, isbn) in the localizedAspectName fields, and then look for the correspondinng aspectRequired boolean fields as well as the corresponding aspectUsage field, which will indicate if the aspect is required, recommended, or optional. In some cases, a product identifier type may be required, but not known/applicable for a product. If this is the case, the seller must still include the corresponding field in the inventory item record, but pass in a default text string. This text string can vary by site, so the seller should use the GeteBayDetails call of the Trading API to get this string value. In the GeteBayDetails call, the seller should include a DetailName field with its value set to ProductDetails. In the response of the call, the seller can see the default string value in the ProductDetails.ProductIdentifierUnavailableText field. The seller will use this value in one or more of the product identifier fields (ean, isbn, upc, or mpn) if a product ID isn't known or applicable.

This container is not initially required, but it is required before an inventory item can be published as an offer, and/or if an inventory item is being updated and product data already exists for that inventory item.

This container is always returned for published offers in the getInventoryItem, bulkGetInventoryItem, and getInventoryItems calls since product data must be defined for published offers, but for unpublished inventory items, this container will only be returned if product details have been defined for the inventory item.
