            "startDateTime":"2020-01-20T14:54:04+00:00"
        },
        "visitors":[
            {

                "lastName":"[Test]NTTS01"
            },
            {
                "lastName":"person",
                "firstName":"A",
                "company":"A corp"
            }
        ]
    },
    "contacts":[

            "userName":"xxxxxxxx"
        },
        {
            "contactType":"ORDERING",
            "userName":"xxxxxxx"
        }
    ],
    "ibxLocation":{
        "ibx":"LD4",
        "cages":[
            {
                "cabinets":[
                    "0000"
                ],
                "accountNumber":"xxxxxxx",
                "cage":"LD4:01:001S14"
            }
