Use the /changes/{uid}/status/ready endpoint to ready a single item with the specified unique ID. The unique ID (uid) is the items classification and the ID combined to create an ID that is unique across all items in Content.
If the item is used by other draft items then you must use the Bulk ready API to mark a group of inter-dependent items as ready for publishing.
Currently, only Assets and Content support workflow.
