In UiPath, how is a queue item identified uniquely?

In UiPath, each queue item is uniquely identified by its transaction ID. This transaction ID serves as a unique key that distinguishes one queue item from another, regardless of attributes like its creation date, priority level, or status. The transaction ID is automatically generated when a queue item is created and ensures that processes can reference and manage specific items accurately within the same queue.

The uniqueness of the transaction ID is crucial for scenarios where multiple items may share similar characteristics (e.g., created at the same time or having the same priority) and for tracking the item's progress through different states in the workflow. This allows for robust handling of items during processing, such as retry mechanisms or when checking the status of individual queue items in the automation process.
