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

Limits

Each Alibaba Cloud account can run a maximum of 500 queries per second (QPS).

Note Resource Access Management (RAM) users of an Alibaba Cloud account share the quota of the account.

Debugging

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.
