Each of these is essentially an order change that is confirmed to apply changes to the original order. The `OrderChange` model's `change_type` property indicates the purpose of the order change: 1. `edit`: The order change is making edits to the order, as explained in the [Order Edit](https://docs.medusajs.com/commerce-modules/order/edit) guide. 2. `exchange`: The order change is associated with an exchange, which you can learn about in the [Order Exchange](https://docs.medusajs.com/commerce-modules/order/exchange) guide. 3. `claim`: The order change is associated with a claim, which you can learn about in the [Order Claim](https://docs.medusajs.com/commerce-modules/order/claim) guide. 4. `return_request` or `return_receive`: The order change is associated with a return, which you can learn about in the [Order Return](https://docs.medusajs.com/commerce-modules/order/return) guide. Once the order change is confirmed, its changes are applied to the order. *** ## Order Change Actions The actions performed on the original order by an order change, such as adding an item, are represented by the [OrderChangeAction data model](https://docs.medusajs.com/references/order/models/OrderChangeAction). The `OrderChangeAction` has an `action` property that indicates the type of action to perform on the order, and a `details` property that holds additional information related to the action. The following table lists the possible `action` values that Medusa uses and the corresponding `details` they carry. |Action|Description|Details| |---|---|---|---|---| |\`ITEM\_ADD\`|Add an item to the order.
