    ],
    "message": "Initial commit",
    "author_name": "John Smith",
    "author_email": "john@example.com",
    "authored_date": "2012-05-28T04:42:42-07:00",

  "message": null,
  "protected": false,
  "created_at": null
}

The type of tag created determines the contents of created_at, target and message:

For annotated tags:
- created_at contains the timestamp of tag creation.
- message contains the annotation.
- target contains the tag object’s ID.
For lightweight tags:
- created_at is null.
- message is null.
- target contains the commit ID.

Errors return status code 405 with an explanatory error message.
