ProcessInstances.UpdateModelDataAsync

Description

Updates the model data for a specified workflow instance within a process instance in the connected AI Command Center.

This API allows runtime modification of model variables for an active workflow instance without affecting other workflows within the same process instance.

---

Signature [C#]

Task UpdateModelDataAsync(ModelData modelData);

---

Parameters

Input

Property	Description
modelData	Contains the Process Instance ID, Workflow Instance ID, and the model variables to update.

---

Remarks

• ProcessInstanceId identifies the parent process instance.
• WorkflowInstanceId identifies the specific workflow instance within the process.
• Only the variables provided in the Data collection are updated.
• The operation executes asynchronously.
• The targeted workflow instance must be active.

Use this API to update runtime model data for a specific workflow instance programmatically.

Example

C#

public void UpdateModelData()
{
    IControlRoomContext context = LoginControlRoom();

    Dictionary<string, string> data = new Dictionary<string, string>()
 {
 { "modelVariable", "Value" }
 };

    ModelData modelData = new ModelData()
 {
        ProcessInstanceId = "e42a93f5d53245d788909fd655b41cfe",
        WorkflowInstanceId = "58bfe04d347540188dfdb55f2e16f5ec",
        Data = data
 };

    context.ProcessInstances.UpdateModelDataAsync(modelData).Wait();

    System.Console.WriteLine("Workflow instance model data has been updated successfully.");
}

C#

public IControlRoomContext LoginControlRoom()
{
    IControlRoomContext context;
    string connectionString;

    connectionString = "ServerUrl=https://demo.onnitellibuddies.com;UserName=demoadmin;Password=password";
    context = new ControlRoomContext(connectionString);

    context.Open();
