POST to /v1/courses with a Course resource body containing name, section, descriptionHeading, and ownerId (teacher's email or me)
Record the id field from the created course response for subsequent calls
POST to /v1/courses/:courseId/courseWork with a CourseWork resource specifying title, workType (ASSIGNMENT or SHORT_ANSWER_QUESTION), dueDate, dueTime, maxPoints, and state PUBLISHED
To attach materials, include a materials array in the CourseWork body with DriveFile, YouTubeVideo, Link, or Form material objects
Verify the assignment appears in the Classroom UI and that the dueDate displays correctly in the student's timezone
Known gotchas
The Google Classroom API requires the authenticating user to be a teacher or co-teacher of the course; domain admin credentials alone do not grant course management access without impersonation via a service account
dueDate and dueTime in CourseWork are in the course owner's configured timezone, not UTC; confirm the owner's timezone setting before scheduling time-sensitive assignments
CourseWork cannot be moved between courses after creation; plan course structure before bulk-creating assignments
