We now know with Veeam U4 you can specify an application/json accept header and have your requests returned as a nice JSON payload which is neat.

In a super basic example here is how to edit a CloudTenant using JSON instead of a XML payload, it also includes the new TenantType node which is required as of v1_4 of the API.

Request

Remember to set Accept: application/json in your headers

PUT http://:9399/api/cloud/tenants/{ID}

{
    "Description": "We are going to update via a JSON payload",
    "Enabled": true,
    "MaxConcurrentTasks": 1,
    "TenantType": {
        "StandaloneTenant": {
            "TenantCredentials": {
                "Username": "AudiEnterprises-FFFTIBI541"
            }
        }
    }
}

Response

You will receive the task reference back, also as JSON

{
    "TaskId": "task-9",
    "State": "Running",
    "Operation": "EditCloudTenant",
    "Links": [
        {
            "Rel": "Delete",
            "Href": "http://cloudconnect1.testcloudspace.co.nz:9399/api/tasks/task-9"
        }
    ],
    "Href": "http://cloudconnect1.testcloudspace.co.nz:9399/api/tasks/task-9",
    "Type": "Task"
}

Result

If you re-fetch the CloudTenant you will see that the description has been updated with the new description, json end-to-end. nice!
