Call this operation to customize multiple device names under the specified product. IoT Platform will check the validity of these names.

Restrictions and guidelines

  • You can specify up to 1,000 device names in a single call.

  • You must use this operation with the BatchRegisterDeviceWithApplyId operation to register multiple devices with unique names under a product.

    Use the following registration procedure:

    1. Call this operation to specify the names of the devices to be registered. IoT Platform returns the application ID (ApplyId). A successful result is returned, indicating that the application for device name verification has been submitted. The actual verification is performed asynchronously and takes a small period of time.
    2. Call QueryBatchRegisterDeviceStatus to query the name setting result.
    3. Call BatchRegisterDeviceWithApplyId to register multiple devices.
    4. (Optional.) Call QueryBatchRegisterDeviceStatus to query the device registration result.
    5. Call QueryPageByApplyId to query the information about the registered devices.
