Configure Start and End Events

The start and end events of a workflow define how a workflow starts and ends.

A Start event defines the start of the workflow. It allows you to specify input arguments in JSON that triggers the workflow so that the workflow starts executing its defined activities.

An End event marks the completion of a workflow. It can be configured to return a JSON response when the workflow completes.

Configure the Start Event

  2. Open the Edit start pane using one of the following options:
    • Select the start event and click Edit start icon on the side of the canvas.

  3. Enter the name of the start event in the Name field.
  4. Provide additional information in the Description field.

    Note:

    The callback URL is provided by the AI agent at runtime and cannot be configured within the workflow. If the workflow is not invoked through an AI agent, a callback request is not made.
