This method retrieves the details of the individual items in an item group. An item group is an item that has various aspect differences, such as color, size, storage capacity, etc. You pass in the item group ID as a URI parameter. You use this method to show the item details of items with multiple aspects, such as color, size, storage capacity, etc. This method returns two main containers; items and commonDescriptions. The items container has an array of containers with the details of each item in the group. The commonDescriptions container has an array of containers for a description and the item ids of all the items that have this exact description. Because items within an item group often have the same description, this decreases the size of the response.
