Using the EthosCE Web Services feature, users have the ability to update enrollment group course lists via a PUT update call.
Warning!
The list sent in field_enrollment_group_courses, is a complete update of values, it is not additive. For instance, given an enrollment group with 6 courses associated, node ids 101 - 106, if an update is made containing only 3 values, node ids 201 - 203, only the 3 newly send courses will appear under Activities. The original 6 courses will no longer be associated with the Enrollment group, however, they will remain in the system, with all associated learner data.
The PHP/Curl script below will update the the enrollment group course list of node id 27 to the course list of nodes 15, 16, and 17.
