  title: Badgr Assertions Backpack API
  version: '2.0'
  description: REST API for the Badgr open digital badging platform (Instructure Canvas Credentials), implementing the Open Badges standard. Endpoints and paths in this document are grounded in the open-source badgr-server URL configuration (apps/issuer, apps/backpack, apps/badgeuser) and Badgr's published v2 API docs. Authentication is OAuth2 bearer token obtained from /o/token with the scopes rw:profile, rw:issuer, and rw:backpack. Regional deployments share the same paths under api.eu.badgr.io, api.ca.badgr.io, and api.au.badgr.io.
