Integrations with Third-Party Tools¶ Here you can find a list of contributed integrations of the Sqreen API with other services that you can use in your own apps. Devise¶ Devise is a popular authentication library for Rails. Now you can use the Sqreen API to screen out risky signups to your Rails app. devise_sqreener passes to you metadata from the Sqreen API about email and IP addresses, and allows you to configure rules around that metadata to reject signups based on their risk to your app's security. And you…? Built something cool with the Sqreen API you'd like to share with the world? We'd love to help! Drop us a line, and we'll include your project right here.
