Publishing to Instructure Canvas "New Quizzes"
Posted by Respondus Support
Canvas New Quizzes requires new APIs and web services to integrate with Respondus 4.0 and other external applications. Once Instructure fully develops the necessary APIs and web services, Respondus Product Management plans to support Canvas New Quizzes with Respondus 4.0.

Meanwhile, faculty should continue to publish to the legacy Classic Quizzes then transfer the quizzes into New Quizzes in the course with the utility provided by Instructure.

Faculty can also follow the steps in "Manual Import of Respondus 4 files into Instructure Canvas" at https://support.respondus.com/support/index.php?/Knowledgebase/Article/View/337/9/
