Orders On Hold
Orders On Hold is a checkbox in WooCommerce Advanced that puts orders On Hold.
In theory, this checkbox can be added to your choice of import(s) such as those from:
Auto-Import (for files), Any API (for custom), BigCommerce, Ecwid, Folder Connect (for FTP), HubSpot, Shopify, Square, Volusion, Web API (for HTTP), and Wix, as well as database connections such as for FileMaker, MySQL, Postgres, and SQLite.
Note there is also an import option for Status that lets you import "1" to set On Hold.
