Resets the unique-certificate-per-product authentication status of a device that is directly connected to IoT Platform, and deletes the current topological relationship of the device.

Usage notes

You cannot use dynamic registration to retrieve the device certificate information after a device that is directly connected to IoT Platform is activated. In this case, you can call the ResetThing operation to reset the device. Then, use dynamic registration to retrieve the new certificate information. The device certificate information includes ProductKey, DeviceName, and DeviceSecret.

Debugging

Alibaba Cloud provides OpenAPI Explorer to simplify API usage. OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

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 instance ID on the Overview page in the IoT Platform console.

Notice
  • If your instance has an ID, you must configure this parameter. If you do not set this parameter, the call fails.
  • If your instance has no Overview page or ID, you do not need to set this parameter.

For more information, see Overview.

ProductKey String No a1KiV******

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 device1

The DeviceName of the device.

Note If you specify this parameter, you must also specify the ProductKey parameter.
IotId String No SR8FiTu1R9tlUR2V1bmi0010a5****

The ID of the device.

Note If you specify this parameter, you do not need to specify ProductKey or DeviceName. The IotId parameter specifies a globally unique identifier (GUID) of the device, which corresponds to a combination of ProductKey and DeviceName. If you specify both IotId and the combination of ProductKey and DeviceName, IotId takes precedence.

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