Call Workflow

Command Description

• You can create multiple workflows in the same automation application. Each workflow is compiled to a separate Python file.
• A called workflow can define input and output parameters.
• Splitting a large automation into subworkflows makes it easier to understand and maintain.

Command Input Parameters

Input Parameter	Type	Description
Workflow Name	str	Name of the workflow to call. Use get_all_flow_names to retrieve the available workflow names

Dynamic input parameter rules:

• Workflow Name is fixed and must identify the workflow to call.
• Use get_target_tab_flow to retrieve the selected workflow's other input parameters.
• Each key in JSON in must exactly match an input parameter name in the target workflow. Each value must be a Python expression available in the current workflow.

Command Output Parameters

Dynamic output parameter rules:

• Use get_target_tab_flow to retrieve the selected workflow's output parameters.
• Each key in JSON out must exactly match an output parameter name in the target workflow.
• Each value in JSON out is a Python variable name, not a string literal. For example, write "ProductPrice": "ProductPrice", not "ProductPrice": "'ProductPrice'".

Example 1

Call Subworkflow B

Subworkflow B input parameters:

Parameter Name	Type
webPage	WebPage
ProductName	str

Subworkflow B output parameters:

Parameter Name	Type
ProductPrice	str
ProductElement	WebElement

The keys in out must exactly match Subworkflow B's output parameter names. The values are variable names and must not include Python string quotes.

      "Render HTML": "False"
    }
  }
]

Example 2

• The subworkflow obtains the number of rows in the specified spreadsheet.

• The current workflow waits until the subworkflow returns or finishes. In this example, the Example workflow executes line 4 before the Main workflow proceeds to line 2.

• The calling workflow uses the returned result.
