# Use `RetireGrant` with an AWS SDK or CLI
<a name="example_kms_RetireGrant_section"></a>

The following code examples show how to use `RetireGrant`.

------
#### [ CLI ]

**AWS 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.  
For more information, see [Retiring and revoking grants](https://docs.aws.amazon.com/kms/latest/developerguide/grant-manage.html#grant-delete) in the *AWS Key Management Service Developer Guide*.

        :return: An instance of GrantManager initialized with the default KMS client.
        """
        kms_client = boto3.client("kms")
        return cls(kms_client)


    def retire_grant(self, grant):
        """
        Retires a grant so that it can no longer be used.

        :param grant: The grant to retire.
        """
        try:
            self.kms_client.retire_grant(GrantToken=grant["GrantToken"])
        except ClientError as err:
            logger.error(
                "Couldn't retire grant %s. Here's why: %s",
                grant["GrantId"],
                err.response["Error"]["Message"],
            )
        else:
            print(f"Grant {grant['GrantId']} retired.")
