Queries the Thing Specification Language (TSL) model of a product.

Limits

Each Alibaba Cloud account can run a maximum of 20 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.

Request parameters

Parameter Type Required Example Description
Action String Yes GetThingModelTsl

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

ProductKey String Yes a1BwAGV****

The key of the product.

You can view the ProductKey on the Product Details page of the IoT Platform console. You can also obtain the ProductKey by calling the QueryProductList operation.

IotInstanceId String No iot_instc_pu****_c*-v64********

The instance ID. This parameter is not required for public instances. However, this parameter is required for Enterprise Edition instances.

ResourceGroupId String No rg-acfm4l5tcwd****

Simple Boolean No true

Specifies whether to retrieve a simplified TSL model.

  • true: retrieves a simplified TSL model.

    A simplified TSL model only includes the identifier and dataType attributes of properties, services, events, and related input or output parameters. Simplified TSL models can be used by device developers for reference.

  • false: retrieves the complete TSL model.

    A complete TSL includes all parameters and values of properties, services, events. Complete TSLs can be used by cloud application developers for reference.

Default value: false.

FunctionBlockId String No BatteryModule

The identifier of a TSL-based custom 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 specify common request parameters when you call this API operation. For more information, see Common request parameters.
