You can publish directly to a Saba Cloud repository folder with Lectora Online as of v4.2 (2018)
To enable this publish option go into Organization Settings (you must be an administrator) and click the option for “Saba Cloud Integration”.
You can also setup your Saba Repository settings in Organization Settings so they will be shared across your organization.
This will surface an option on the publishing dialog to select a Saba Cloud repository folder. Select the folder you want to push your published content to and proceed with publishing. After publish finishes it gives you a button to send the published course to the folder you specified.
