(Optional) Enter the page ID of the parent wiki page. You can find this identifier by accessing the parent page in question, and then selecting "Page Information" or "Page History" from the Confluence Tools menu. The pageId will appear as a query parameter in the address bar. e.g. (pageId=1234567)

If a parent is not specified, the space home will be used as the parent.

This field is used for creating new pages only. If the page already exists, then parentId is discarded.
