    note: Faithful OpenAPI reconstruction of the operations, paths, HTTP methods, authentication scheme, permission scopes, pagination model and documented request fields published on developer.class.com. Request/response object schemas capture only fields named in the public documentation; no fields were invented. This is an API Evangelist generated spec, not a Class-published artifact.
  description: REST API for Class (fka ClassEDU), the virtual classroom platform built for Zoom and Microsoft Teams. The API lets administrators and integrators provision classes, manage enrollments, generate learner launch links, schedule class dates, manage reusable class templates, manage non-learner users, and pull attendance and engagement reporting. Authentication uses a per-organization API key presented as a Bearer token, gated by permission scopes.
