This gem provides an OmniAuth strategy for Box OAuth2.

Add this line to your application's Gemfile:

gem 'omniauth-box2'

Then run:

bundle install

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :box, ENV.fetch('BOX_CLIENT_ID'), ENV.fetch('BOX_CLIENT_SECRET')
end

• Box developer console: https://developer.box.com/
• Register callback URL (example): https://your-app.example.com/auth/box/callback

• callback_url
• Request-phase query options can be passed directly to /auth/box when supported by Box OAuth endpoints.

Example payload from request.env['omniauth.auth'] (real flow shape, anonymized):

{
  "uid": "123456789",
  "info": {
    "name": "Sample User",
    "email": "sample@example.test"
  },
  "credentials": {
    "token": "sample-access-token",
    "refresh_token": "sample-refresh-token",
    "expires": false,
    "scope": "root_readonly"
  },
  "extra": {
    "raw_info": {
      "type": "user",
      "id": "123456789",
      "name": "Sample User",
      "login": "sample@example.test",
      "created_at": "2012-05-09T09:12:30-07:00",
      "modified_at": "2026-03-04T19:21:50-08:00",
      "language": "en",
      "timezone": "Europe/Amsterdam",
      "space_amount": 999999999999999,
      "space_used": 74112195069,
      "max_upload_size": 53687091200,
      "status": "active",
      "job_title": "CEO",
      "phone": "+390000000000",
      "address": "",
      "avatar_url": "https://example.app.box.com/api/avatar/large/123456789",
      "notification_email": null
    }
  }
}

Notes:

• uid is mapped from raw_info.id (as string)
• info.name is mapped from raw_info.name
• info.email is mapped from raw_info.login
• credentials includes token, plus refresh_token when provided by Box
• extra.raw_info is the full users/me response

The strategy uses current Box OAuth and API endpoints:

• Authorize URL: https://account.box.com/api/oauth2/authorize
• Token URL: https://api.box.com/oauth2/token
• User info URL: https://api.box.com/2.0/users/me
