Publish courses and activities as LTI
You can now share your learning content with external entities by using the Publish as LTI tool feature in Moodle 3.1.
Share individual activities and resources or the entire course. Other systems using Learning Tools Interoperability® (LTI) can connect to a Moodlerooms site that has published course content as LTI. Users in the external system are launched into your Moodlerooms site and interact with the Moodlerooms content as if they are enrolled in the course.
Any user that accesses the content in your Moodlerooms site in this way is counted as an active user for Moodlerooms billing purposes.
