The Avalon REST API offers a way to get and modify objects and metadata. Use it to interact with collections, media objects, and supplemental files.

Authentication

All API methods are protected by token authentication. A specified token is passed through http header 'Avalon-Api-Key'. A matching token must be configured in in Avalon's database. Creating and viewing tokens can be done via rake tasks. Every token is associated with an Avalon user. User sessions authenticated against an API token will assume the same authorization rights as the associated user.

$ rake avalon:token:generate username=archivist email=archivist1@example.com
