New API Documentation - Developer Preview Available

We are excited to announce the developer preview of our new API documentation for AWS SDK for JavaScript v3. Please follow instructions on the landing page to leave us your feedback.

Class DeleteImportedKeyMaterialCommandProtected

Deletes key material that you previously imported. This operation makes the specified KMS key unusable. For more information about importing key material into KMS, see Importing Key Material in the Key Management Service Developer Guide.

When the specified KMS key is in the PendingDeletion state, this operation does not change the KMS key's state. Otherwise, it changes the KMS key's state to PendingImport.

After you delete key material, you can use ImportKeyMaterial to reimport the same key material into the KMS key.

The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the Key Management Service Developer Guide.

Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.

Required permissions: kms:DeleteImportedKeyMaterial (key policy)

Use a bare-bones client and the command you need to make an API call.

import { KMSClient, DeleteImportedKeyMaterialCommand } from "@aws-sdk/client-kms"; // ES Modules import
// const { KMSClient, DeleteImportedKeyMaterialCommand } = require("@aws-sdk/client-kms"); // CommonJS import
const client = new KMSClient(config);
const input = { // DeleteImportedKeyMaterialRequest
KeyId: "STRING_VALUE", // required
const command = new DeleteImportedKeyMaterialCommand(input);
const response = await client.send(command);
// {};







DependencyTimeoutException (server fault)

KMSInternalException (server fault)

The request was rejected because an internal exception occurred. The request can be retried.


KMSInvalidStateException (client fault)

The request was rejected because the state of the specified resource is not valid for this request.

This exceptions means one of the following:

  • The key state of the KMS key is not compatible with the operation.

    To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide .

  • For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception.


NotFoundException (client fault)

The request was rejected because the specified entity or resource could not be found.


UnsupportedOperationException (client fault)
