  description: >-
    The Edlink API provides a unified, normalized interface to school roster and
    learning data across hundreds of SIS and LMS source systems. The Graph API
    operates at the institution level using an Integration Access Token to read
    districts, schools, classes, sections, courses, people, and enrollments that
    have been shared with an integration. Single Sign-On is provided over OAuth
    2.0 and OpenID Connect, and source/integration metadata plus change events
    support incremental synchronization. All requests are authenticated with a
    Bearer token.
