This method is a bridge between the eBay legacy APIs, such as Shopping, and Finding and the eBay Buy APIs. There are differences between how legacy APIs and RESTful APIs return the identifier of an "item" and what the item ID represents. This method lets you use the legacy item ids retrieve the details of a specific item, such as description, price, and other information the buyer needs to make a purchasing decision. It also returns the RESTful item ID, which you can use with all the Buy API methods. For more information about how to use legacy ids with the Buy APIs, see Legacy API compatibility in the Buying Integration guide. This method returns the item details and requires you to pass in either the item ID of a non-variation item or the item ids of both the parent and child of an item group. An item group is an item that has various aspect differences, such as color, size, storage capacity, etc. When an item group is created, one of the item variations, such as the red shirt size L, is chosen as the "parent". All the other items in the group are the children, such as the blue shirt size L, red shirt size M, etc. The fieldgroups URI parameter lets you control what is returned in the response. Setting fieldgroups to PRODUCT, adds additional fields to the default response that return information about the product of the item. For more information, see fieldgroups.
