This call retrieves details on one or more order line items for a specified eBay listing. Auctions and single-quantity, fixed-price listings can only have one order line item, but a multiple-quantity and/or multiple-variation, fixed-priced listing can have numerous order line items.

To find one or more order line items for an eBay listing, an ItemID value can be passed in. If a user wanted to retrieve a specific order line item, an ItemID value and a an TransactionID value can be passed in, or an OrderLineItemID value can be passed in instead of an ItemID/TransactionID pair.

The NumberOfDays or the ModTimeFrom and ModTimeTo date range filters can be used to retrieve order line items generated (or last modified) within a specific range of time. The maximum date range that can be set is 30 days, and the ModTimeFrom date value cannot be set any further back than 90 days in the past. If no date range filters are used, all order line items (associated with the specified listing) generated (or last modified) in the last 30 days are retrieved. Date ranges are generally only used for multiple-quantity or multiple-variation, fixed-price listings that can have multiple order line items.

There are also pagination filters available that allow the user to control how many and which order line items are returned on each page of a results set.
