omniauth-flickr

  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :flickr, ENV['FLICKR_KEY'], ENV['FLICKR_SECRET'], scope: 'read'
  end

A scope must be set, which translate to the perms parameter in the request url. Valid perms (scopes) are read, write and delete. Info about the authenticated user is fetched from flickr.people.getInfo.

Example AuthHash from a successful authentication:

provider: flickr
uid: 62839091@N05
info: !ruby/hash:OmniAuth::AuthHash::InfoHash
  name: Example User
  nickname: example_user
  ispro: 0
  iconserver: '8061'
