In Canvas, Free for teacher edition, the system is set to allow self-registration. Using the UI, the teacher can add a user that doesn't yet have a Canvas account by providing the following information
"Lastname, Firstname" <firstname.lastname@example.org>
Once added, an email is sent to that user prompting them to create an account and log in to Canvas, then to Accept the invitation to the course.
Which API calls would an instructor make to accomplish the same actions?
