Pass custom parameters, primarily to custom plugins and custom nodes, when calling Alibaba Cloud Model Studio's Agent Application and Workflow Application (which replace agent orchestration applications).
Create an API key and export the API key as an environment variable. If you use an SDK to make calls, install the DashScope SDK.
Custom plugin parameters
This article uses the dormitory convention query tool to demonstrate how to pass parameters to a custom plugin using an API.
Parameters for custom plugins are passed via an associated Agent Application or a Workflow Application's plugin node.
The following example shows how to pass custom plugin parameters for an Agent Application.
Usage
Step 1: Create a custom plugin
If you have already created a plugin tool or imported a plugin, skip this step.
Create a custom plugin: Go to the Plugins page in the Model Studio console and click Add Custom Plug-in. Enter the plugin information. If authentication is required, turn on the Enable Authentication switch and configure the settings.
Example Plugin Description: Queries dormitory conventions and looks up specific entries by numeric index.
Example Plugin URL: https://domitorgreement-plugin-example-icohrkdjxy.cn-beijing.fcapp.run

Note: The Plug-in Description briefly summarizes the plugin's purpose. This helps the large model decide whether to call the plugin for a given task. Describe it in natural language.
Create a tool: Fill in the tool information and configure the input and output parameters. Note:
The Tool Description helps the large model better understand the tool's functions and use cases. Use natural language and provide examples if possible.
A descriptive Parameter Name helps the large model understand the information it represents.
The Parameter Description explains the function of the input parameter. It should be concise and accurate to help the large model determine the correct value to use.
You must select Business Pass-through for the input parameter's Passing Method.
In this example, the dormitory convention content index,
article_index, is set as a passthrough parameter.
Click Test Tool. After the test passes, Publish the plugin.
Step 2: Associate a plugin with an agent
You can only associate plugins with Agent Application that are in the same workspace.
On a published plugin's card, click Add to Agent and select an agent application.
Alternatively, click + Plugin within an application to associate a custom plugin.
Finally, Publish the application.
Step 3: API call
When authentication is not required: To call a custom plugin via an API, use the
user_defined_paramsparameter ofbiz_paramsto pass the custom plugin information, replaceyour_plugin_codewith the actual plugin ID, and pass the key-value pairs of the input parameters configured in the plugin.You can find the plugin ID on the plugin card.
In this example, passing a value of 2 to the
article_indexparameter queries the content of the second dormitory convention and returns the correct result.Python

The second article of the dormitory convention is as follows: "Roommates must help, care for, and learn from each other to achieve mutual improvement. They must be tolerant, forgiving, respectful, and sincere." This suggests that roommates should foster a positive living and learning environment by supporting and helping each other, while also learning to understand and respect others.

Pass custom node parameters
This topic uses the Querying administrative divisions by city name example to demonstrate how to pass custom node parameters to an application through an API call.
Custom node parameters for an application are passed through the start node of a Workflow Application.
The following example shows how to pass custom parameters to the start node in a Workflow Application.
Usage
Step 1: Configure custom node parameters
Go to the My Applications page in the Model Studio console. Select a Workflow Application and define custom parameters for its start node. For this example, create a String variable named city. Then, insert the city and query variables into the prompt and Publish the application.
Step 2: Make an API call
When you make the API call, pass the city value in the biz_params field and the query value in the prompt field.
Python
sample request
import os
from http import HTTPStatus
from dashscope import Application
# Pass custom parameters for a workflow application.
biz_params = {"city": "Hangzhou"}
response = Application.call(
# If you have not configured an environment variable, you can use your Model Studio API key by replacing the following line with: api_key="sk-xxx".
# We recommend that you do not hardcode the API key in your code in a production environment to reduce the risk of API key leaks.
api_key=os.getenv("DASHSCOPE_API_KEY"),
app_id='YOUR_APP_ID', # Replace with your actual application ID.
prompt='Query the administrative divisions of this city',
biz_params=biz_params # Pass business parameters.
)
