Queries all the property snapshots of a device or digital twin node.

Usage notes

To query the property data of a digital twin node, you must set the IotId parameter to the ID of the digital twin node.

QPS limits

Each Alibaba Cloud account can run up to 200 queries per second (QPS).

Note The RAM users of an Alibaba Cloud account share the quota of the Alibaba Cloud account.


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


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


The ID of the instance. You can view the ID of the instance on the Overview page in the IoT Platform console.

  • If your instance has an ID, you must specify the ID for this parameter. Otherwise, the call fails.
  • If no Overview page or instance ID appears in the console, you do not need to configure this parameter.

For more information, see Overview.


The ProductKey of the product to which the device belongs.


If you specify this parameter, you must also specify the DeviceName parameter.


The DeviceName of the device.


If you specify this parameter, you must also specify the ProductKey parameter.


The ID of the device or digital twin node whose property data you want to query.

  • You can call the QueryDeviceInfo operation to query the ID of the device.
  • Log on to the IoT Platform console. On the Twin Details page, click the digital twin node to view its ID.

If you specify this parameter, you do not need to specify the ProductKey and DeviceName parameters. 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 the IotId, ProductKey, and DeviceName parameters, the value of the IotId parameter takes precedence.


The identifier of the custom TSL module. Each identifier is unique in a product.

If you do not specify this parameter, the system queries the data of the default module.

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

Response parameters


The error code returned if the call fails. For more information, see Error codes.


The data returned if the call succeeds. For more information, see List.

  • double: double-precision floating-point number
  • enum: enumeration
  • bool: Boolean
  • text: character
  • date: time (string-type UTC timestamp in milliseconds)
  • array: array
  • struct: structure

The identifier of the property.


The name of the property.


The time when the property was modified, in milliseconds.


The unit of the property value.


The value of the property.

ErrorMessageStringA system exception occurred.

The error message returned if the request fails.


The ID of the request.


Indicates whether the call was successful.

  • true: The call was successful.
  • false: The call failed.
