//!The Inventory API exposes a set of objects to represent inventory adjustments
//! and physical counts for quantities of products (as item variations) and
//! transitions of stocked products to the relevant inventory state.
//!
//! hese include the following key data types for the Inventory API:

//! InventoryCount - computed quantity of an item variation at a specific location.
//! InventoryAdjustment - quantity of an item variation transitioning from one state to another.
//! InventoryPhysicalCount - verified quantity of an item variation at a specific location.
//! SourceApplication - application that makes an inventory change and helps trace sources of inventory changes.
