- **endTaskId**: The unique identifier of the task where the connection terminates.
- **startIndex**: The index position within the start task from which the connection begins (useful for tasks with multiple connection points).
- **endIndex**: The index position within the end task where the connection attaches.
- **lag**: The lag time, typically in milliseconds or a project-specific unit, representing any delay between the linked tasks.
