OmniAuth Spotify Strategy

omniauth-spotify provides a Spotify OAuth2 strategy for OmniAuth.

Add this line to your application's Gemfile:

gem 'omniauth-spotify'

Then run:

bundle install

Configure OmniAuth in your Rack/Rails app:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :spotify, ENV.fetch('SPOTIFY_CLIENT_ID'), ENV.fetch('SPOTIFY_CLIENT_SECRET'),
           scope: 'user-read-email user-read-private'
end

• Spotify developer dashboard: https://developer.spotify.com/dashboard
• OAuth scopes reference: https://developer.spotify.com/documentation/web-api/concepts/scopes
• Register callback URL (example): https://your-app.example.com/auth/spotify/callback
• The redirect URI must match exactly in Spotify's dashboard.
• Spotify requires HTTPS redirect URIs except for loopback IP literals such as http://127.0.0.1:3000/auth/spotify/callback; localhost is not accepted.

• scope
• show_dialog

Spotify may skip the permission dialog when the user already granted access. To force it:

• set request.env['rack.session']['omniauth_spotify_force_approval?'] = true, or
• pass show_dialog=true on the auth request URL.

Backward compatibility is preserved for the historical misspelled key: ommiauth_spotify_force_approval?.

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

{
  "uid": "1234567890",
  "info": {
    "name": "1234567890",
    "nickname": "1234567890",
    "email": "user@example.test",
    "urls": {
      "spotify": "https://open.spotify.com/user/1234567890"
    },
    "country_code": "IT",
    "product": "free",
    "follower_count": 24
  },
  "credentials": {
    "token": "sample-access-token",
    "refresh_token": "sample-refresh-token",
    "expires_at": 1710000000,
    "expires": true,
    "scope": "user-read-email user-read-private"
  },
  "extra": {
    "raw_info": {
      "country": "IT",
      "display_name": "1234567890",
      "email": "user@example.test",
      "explicit_content": {
        "filter_enabled": false,
        "filter_locked": false
      },
      "external_urls": {
        "spotify": "https://open.spotify.com/user/1234567890"
      },
      "followers": {
        "href": null,
        "total": 24
      },
      "href": "https://api.spotify.com/v1/users/1234567890",
      "id": "1234567890",
      "images": [],
      "product": "free",
      "type": "user",
      "uri": "spotify:user:1234567890"
    }
  }
}

info.email, info.image, info.birthdate, info.country_code, info.product, and info.follower_count are included only when Spotify returns those fields.

The strategy still uses Spotify's authorization-code flow and GET https://api.spotify.com/v1/me for the current user profile.

Recent changelog items reviewed:

• February 2026 Development Mode changes: Spotify deprecated country, email, explicit_content, followers, and product and may omit them from GET /me user payloads for affected development-mode apps. The gem treats these fields as optional and omits absent values from info.
• March 2026 changelog: Spotify reverted the February removal of Album and Track external_ids. This gem does not call Album or Track endpoints and does not map external_ids, so no code change is required for that reversal.
• February 2025 redirect URI security changes: Spotify rejects localhost redirect URIs and requires HTTPS except for explicit loopback IP literals.
• Development Mode access changes: if GET /me returns 403 with a message requiring Spotify Premium for the app owner, OAuth token exchange may still be working; the Web API call is blocked by Spotify account/app policy, not by this strategy's auth-hash mapping.
