Crowdmark has introduced a new interface. As of July 2023, the new interface will be implemented. 

This document covers the steps to get started in Crowdmark’s all-new interface. Please be aware that this document speaks about importing class lists, but that step is done for you via the Crowdmark LTI plugin.
