  title: commercetools Change History Carts Inventory API
  description: The commercetools Change History API provides a queryable audit log of all changes made to resources within a Composable Commerce project. It records mutations applied to resources such as products, orders, customers, discounts, and carts, along with metadata about who made the change and when. The API is hosted on separate regional endpoints from the main HTTP API and supports filtering by resource type, date range, user, and API client. It is useful for compliance workflows, debugging unexpected state changes, and building audit trails for regulated industries.
