  title: Canvas LMS Grade a Student by Section Enrollment
  summary: Find a student via course section enrollments, then grade their assignment.
  description: >-
    A section-scoped grading flow for Canvas. Because the covered REST surface
    does not expose a create-section operation, this workflow adapts the
    "create section then enroll" theme to a supported pattern: it lists the
    course's student enrollments (which carry the course_section_id), recovers a
    student in the desired section, reads that student's submission for an
    assignment, and posts a grade. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
