  title: D2L Brightspace Valence Learning Framework Assignments Discussions API
  description: 'The Valence Learning Framework API is the public REST API for the D2L Brightspace learning management system (LMS). It is served from an institution''s own Brightspace host under https://{host}/d2l/api/ and is divided into two product components: "lp" (Learning Platform - users, roles, enrollments, org units, and Data Hub) and "le" (Learning Environment - content, grades, assignments/dropbox, quizzes, discussions, calendar, news, and learning outcomes). Each component is independently versioned; the version segment in a route (for example lp/1.53 or le/1.92) varies by installed Brightspace product version, and clients should confirm supported versions via GET /d2l/api/versions/ before hard-coding a value. Requests are authenticated with OAuth 2 bearer tokens issued by the D2L auth service (https://auth.brightspace.com/core/connect/token) using the authorization code grant; the older ID-Key (app-id/user-id signed URL) scheme is deprecated. Scopes take the form group:resource:action, for example users:userdata:read. The version values baked into the paths below are illustrative of a recent release and must be adjusted to the target instance. "Valence" is the historical name of the API framework; "D2L" is the vendor and "Brightspace" the product.'
