Long-running workflows in UiPath are designed to handle processes that require logical fragmentation or human intervention, such as validations, approvals, and exception handling. These workflows facilitate asynchronous interactions between human users and robots, allowing for efficient collaboration. For example, a workflow can be paused until a human completes a necessary task or makes a decision, after which the workflow resumes12. This characteristic is essential for processes that cannot be fully automated and require human input at certain stages.
