This article outlines how to view student appointment activity (registrations, check-ins, cancelations, and no-shows) in the instructor view.
Navigate to your Canvas course site and click the RegisterBlast link in your course navigation menu.
Click the History link at the top of the page.
The History view shows student registrations and can be filtered by date range.
If the Registerblast option does not appear in your course navigation menu, click the Settings option instead and enable it under the Navigation Settings tab in the course settings.
