Use DeleteAlias with an AWS SDK or CLI

To delete an AWS KMS alias

The following delete-alias example deletes the alias alias/example-alias. The alias name must begin with alias/.

aws kms delete-alias \
    --alias-name alias/example-alias

This command produces no output. To find the alias, use the list-aliases command.

For more information, see Deleting an alias in the AWS Key Management Service Developer Guide.
