Start

Definition

Define the initial parameters for starting a workflow.

You can customize the input variables for initiating the workflow in the start node. Every workflow requires a start node.

Workflow Start Node

The Start Node supports four different types of input variables:

• Text

• Paragraph

• Dropdown Options

• Number

Once configured, the workflow will prompt for the values of the variables defined in the start node during execution.

Tip: In Chatflow, the start node provides built-in system variables: sys.query and sys.files.

sys.query is used for user input questions in conversational applications.

sys.files is used for file uploads in conversations, such as uploading an image, which needs to be used in conjunction with an image understanding model.
