Request parameters

Parameter Type Required Example Description
Action String Yes QueryDeviceOriginalPropertyStatus

The operation that you want to perform. Set the value to QueryDeviceOriginalPropertyStatus.

Asc Integer Yes 0

The chronological order in which property data is queried. Valid values:

  • 0: in reverse chronological order.
  • 1: in chronological order.
PageSize Integer Yes 10

The number of entries to return on each page. Valid values: 1 to 50.

IotInstanceId String No iot_instc_pu****_c*-v64********

The instance ID. This parameter is not required for public instances. However, this parameter is required for Enterprise Edition instances that you have purchased.

ProductKey String No a1BwAGV****

The ProductKey of the product to which the device belongs.

Note If you specify this parameter, you must also specify the DeviceName parameter.
DeviceName String No light

The name of the device.

Note If you specify this parameter, you must also specify the ProductKey parameter.
NextPageToken String No Bo***x44Qx

The identifier of the next page. If the next page exists, this parameter is returned. In this case, you must add the value of the parameter to the next request.

IotId String No Q7uOhVRdZRRlDnTLv****00100

The ID of the device. It is the unique identifier that IoT Platform generated for the device.

Note If you specify this parameter, you do not need to specify the ProductKey or DeviceName parameter. The IotId parameter specifies a unique identifier for the device, and corresponds to a combination of the ProductKey and DeviceName parameters. If you specify the IotId parameter and a combination of the ProductKey and DeviceName parameters at the same time, the IotId parameter takes precedence.

In addition to the preceding operation-specific request parameters, you must specify common request parameters when you call this API operation. For more information, see Common request parameters.
