AddItemResponseType ( AbstractResponseType )

Unique identifier of the secondary category in which the item was listed. This field is only returned if the Item.CategoryMappingAllowed boolean field is set to true in the request (or omitted) and the Category ID passed in as the secondary listing category was automatically mapped to a new Category ID by eBay. If the secondary category ID passed in the request is still active/valid, this field is not returned.

Note: The Item.CategoryMappingAllowed field value in the request now defaults to true if omitted. Previously, the default value was false, so a user had to include this field and set it to true in order for eBay to map an outdated Primary or Secondary Category ID to the updated Category ID.

This container is an array of one or more listing fee/upgrade discount types being offered by eBay to the seller.

Date and time when the new listing is scheduled to end based on the start time and the listing duration value that was set in the ListingDuration field at listing time. If the value of ListingDuration was set to GTC (Good 'Til Cancelled) this value will be set one month ahead of the start time, and this value will continue to be updated one month ahead each time the GTC listing needs to be renewed. Fixed-price listings get renewed automatically as long as there is still a quantity of 1 or above, or even if the quantity is 0, but the 'out-of-stock control' feature is enabled.

Note that GTC is not a supported listing duration for auction listings, but is the only supported listing duration for fixed-price listings except for a few motor vehicle categories on eBay Motors US, eBay UK, and eBay Italy.

Note: As of July 1, 2019, the Good 'Til Cancelled renewal schedule has been modified from every 30 days to once per calendar month. For example, if a GTC listing is created July 5, the next monthly renewal date will be August 5. If a GTC listing is created on the 31st of the month, but the following month only has 30 days, the renewal will happen on the 30th in the following month. Finally, if a GTC listing is created on January 29-31, the renewal will happen on February 28th (or 29th during a 'Leap Year'). See the Good 'Til Cancelled listings update in the Spring 2019 Seller Updates for more information about this change.

This container is an array of fees associated with the creation of the listing. The fees in this container will not include any fees that are based on the purchase price (such as Final Value Fee) and only come into play when the listing has a sale.

All listing fee types are returned, even if those fees are not applicable for the new listing and are '0.0'.

Note: The currency used for all fees returned under the Fees container reflects the currency used for the listing site, and not necessarily in the seller's default/home currency. For example, if a Canadian seller is using the AddItem call to list an item on the eBay US site, the currency type shown for each fee will be USD and not CAD.

Unique identifier for the new listing. This field is returned as long as the listing was successfully created.

Container consisting of one or more Recommendation containers. Each Recommendation container provides a message to the seller on how a listing can be improved or brought up to standard in regards to top-rated seller/listing requirements, mandated or recommended Item Specifics, picture quality requirements, pricing and/or listing format recommendations, recommended keywords and/or Item Specifics in a Title, and/or a recommendation to offer fast handling (same-day handling or handling time of 1 day) and/or a free shipping option in order to qualify the listing for a Fast 'N Free badge.

This container is only returned if the IncludeRecommendations flag was included and set to 'true' in the AddItem request, and if at least one listing recommendation exists for the newly created listing. If one or more listing recommendations are returned, it will be at the seller's discretion about whether to revise the item based on eBay's listing recommendation(s).

This container holds an array of one or more products in the eBay product catalog that appear to match the product being listed, just based on the information in the listing. This container will not be returned if no similar products were found in the eBay product catalog.

Starting date and time for the new listing. This value is based on the time the listing was received and processed, or the time the item will be listed if the seller included the Item.ScheduleTime field in the request and set a custom start time of the listing (in the future).
