RetireGrant

Deletes a grant. Typically, you retire a grant when you no longer need its permissions. To identify the grant to retire, use a grant token, or both the grant ID and a key identifier (key ID or key ARN) of the KMS key. The CreateGrant operation returns both values.

This operation can be called by the retiring principal for a grant, by the grantee principal if the grant allows the RetireGrant operation, and by the AWS account in which the grant is created. It can also be called by principals to whom permission for retiring a grant is delegated.

For detailed information about grants, including grant terminology, see Grants in AWS KMS in the AWS Key Management Service Developer Guide . For examples of creating grants in several programming languages, see Use CreateGrant with an AWS SDK or CLI.

Cross-account use: Yes. You can retire a grant on a KMS key in a different AWS account.

Required permissions: Permission to retire a grant is determined primarily by the grant. For details, see Retiring and revoking grants in the AWS Key Management Service Developer Guide.

Related operations:

Eventual consistency: The AWS KMS API follows an eventual consistency model. For more information, see AWS KMS eventual consistency.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

DryRun

Checks if your request will succeed. DryRun is an optional parameter.

To learn more about how to use this parameter, see Testing your permissions in the AWS Key Management Service Developer Guide.

Type: Boolean

Required: No

GrantId

Identifies the grant to retire. To get the grant ID, use CreateGrant, ListGrants, or ListRetirableGrants.

Grant ID Example - 0123456789012345678901234567890123456789012345678901234567890123

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Required: No

GrantToken

Identifies the grant to be retired. You can use a grant token to identify a new grant even before it has achieved eventual consistency.

Only the CreateGrant operation returns a grant token. For details, see Grant token and Eventual consistency in the AWS Key Management Service Developer Guide.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 8192.

Required: No

KeyId

The key ARN KMS key associated with the grant. To find the key ARN, use the ListKeys operation.

For example: arn:aws:kms:us-east-2:444455556666:key/1234abcd-12ab-34cd-56ef-1234567890ab

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: No

Response Elements

If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.

Errors

For information about the errors that are common to all actions, see Common Errors.

DependencyTimeoutException

The system timed out while trying to fulfill the request. You can retry the request.

HTTP Status Code: 500

DryRunOperationException

The request was rejected because the DryRun parameter was specified.

HTTP Status Code: 400

InvalidArnException

The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.

HTTP Status Code: 400

InvalidGrantIdException

The request was rejected because the specified GrantId is not valid.

HTTP Status Code: 400

InvalidGrantTokenException

The request was rejected because the specified grant token is not valid.

HTTP Status Code: 400

KMSInternalException

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

HTTP Status Code: 500

KMSInvalidStateException

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 AWS KMS operation, see Key states of AWS KMS keys in the AWS 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.

HTTP Status Code: 400

NotFoundException

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

HTTP Status Code: 400
