# Import Operations

Represents the import status of an individual resource.

After you [create an Import Request](/api/import-export/import-requests.md#create-import-request), the system creates one [ImportOperation](/api/import-export/import-operation.md#importoperation) per resource in the Import Request.

ImportOperations contain information about the resource being imported, such as its [ProcessingState](/api/import-export/import-operation.md#processingstate) and any [UnresolvedReferences](/api/import-export/import-operation.md#unresolvedreferences). If some actions within an ImportOperation succeed and others fail, the ImportOperation is assigned the `partiallyImported` state.

For Product imports (including re-imported Products), the `waitForMasterVariant` state is assigned only when the Product Type has required Variant Attributes and the import payload is missing Master Variant data.

To monitor the import process, use [Get ImportOperation](/api/import-export/import-operation.md#get-importoperation) to view the status of a single ImportOperation, or [Query ImportOperations in ImportContainer](/api/import-export/import-operation.md#query-importoperations-in-importcontainer) to view all of the ImportOperations within a single [ImportContainer](/api/import-export/import-container.md#importcontainer).

ImportOperations are automatically deleted **48** hours after they are created.

To achieve the best performance with the Import API, we recommend to use fewer than **200000** Import Operations per Import Container.
