Resets the unique-certificate-per-product registration status of a device that is directly connected to IoT Platform, or deletes the current topology of the device.
Usage notes
-
After you use dynamic registration to obtain the device certificate information of a directly connected device and activate the device, you can call this operation to reset the dynamic registration status of the status to unregistered in the IoT Platform console. Then, you can use dynamic registration again to obtain the device certificate information. The device certificate information includes ProductKey, DeviceName, and DeviceSecret.Note This operation is called to reset the dynamic registration status instead of activation status of a device. After you call the operation to reset the dynamic registration status of a device, the status of the device in the IoT Platform console is not reset to inactive.
- If you specify a gateway and the number of sub-devices that belong to the gateway exceeds 2,000, you can call this operation to create a device job to delete the topological relationships in an asynchronous manner. The operation returns the JobId parameter.

Request parameters
| Parameter | Type | Required | Example | Description |
|---|---|---|---|---|
| Action | String | Yes | ResetThing |
The operation that you want to perform. Set the value to ResetThing. |
| IotInstanceId | String | No | iot-cn-0pp1n8t**** |
The ID of the instance. You can view the ID of the instance on the Overview page in the IoT Platform console. Notice
For more information, see Instance overview. |
| ProductKey | String | No | a1KiV****** |
The ProductKey of the product to which the device belongs. Note If you specify a value for this parameter, you must also specify a value for the DeviceName parameter.
|
| DeviceName | String | No | device1 |
The DeviceName of the device. Note If you specify a value for this parameter, you must also specify a value for the ProductKey parameter.
|
| IotId | String | No | SR8FiTu1R9tlUR2V1bmi0010a5**** |
The ID of the device. Note If you specify a value for this parameter, you do not need to specify a value for
the ProductKey or DeviceName parameter. The IotId parameter specifies a globally unique identifier (GUID) for the device. The value
of the IotId parameter corresponds to a combination of the values of the ProductKey and DeviceName parameters. If you specify a value for the IotId parameter and values for the ProductKey and DeviceName parameters, the value of the IotId parameter takes precedence.
