Use RetireGrant with an AWS SDK or CLI

To retire a grant on a customer master key

The following retire-grant example deletes a grant from a KMS key.

The following example command specifies the grant-id and the key-id parameters. The value of the key-id parameter must be the key ARN of the KMS key.

aws kms retire-grant \
    --grant-id 1234a2345b8a4e350500d432bccf8ecd6506710e1391880c4f7f7140160c9af3 \
    --key-id arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

This command produces no output. To confirm that the grant was retired, use the list-grants command.
