Updating the attributes of an existing device

To update all device attributes, we use the HTTP PUT method and, if it is successful, the response should be HTTP 200 OK. In the following example, we will update the attribute of the existing device with ID 11. If the device ID is not present it should create a new device. If the intent is to only update certain attributes, we use the HTTP PATCH operations and it should update the attribute specified. If the given attribute has issued an error response, we should use the HTTP status code 4xx ranges, such as error code 400 for a bad request.

In the following example, we will update details of the device with ID 11:

HTTP PUT --> /iiot/devices/11    {        "name": "device-liquifier1", "assetType": "liquifier1", ...
