OneData provides external workflow support so that you can have integrated data and workflow management from an external system. OneData passes pending workflow transactions to the external system using iHooks and retrieves workflow items from the external system using workflow API methods.

The external approver can approve, reject, delegate, or save changes to the pending workflow transaction, but cannot use the Request Info action. OneData notifies the external approver when an action in OneData changes a step in the approval process for the pending transaction.

The following diagram shows the integrated external workflow of transactions between OneData and an external system.
