Frequently asked questions
Are Auth0 Actions developer-friendly?
Auth0 Actions are highly developer-friendly, featuring an in-browser IDE, version control, and support for the full Node.js ecosystem. Developers can test their custom logic in a sandbox environment before deploying it to production, helping ensure that identity customizations are reliable, maintainable, and highly performant for millions of users. Auth0 provides Actions Types NPM which allows coding with Actions TypeScript definitions in external IDEs. This in combination with CLI, CI/CD, or API tooling can be used to develop Actions outside of the Auth0 Dashboard. Actions Types NPM also helps AI Agents to understand how Actions objects and interfaces are defined, improving the accuracy of the generated code.

Can Auth0 Actions integrate with third-party integrations?
Yes, Auth0 Actions supports custom Actions that can be used to integrate with 3rd Party applications or services. In addition, there is also Auth0 Marketplace which provides a series of pre-built integrations with tools like Slack, Segment, and Salesforce. This allows developers to easily connect identity events to the rest of their tech stack, automating security responses and data synchronization without writing custom API integration code from scratch, accelerating time-to-market. https://auth0.com/docs/customize/actions/use-cases
Can I use Auth0 Actions for fraud detection?
Yes, Auth0 Actions can be used to integrate third-party risk engines and fraud detection tools directly into the authentication pipeline. For example, you can write an Action that calls an external service to check a user's IP reputation or verify their identity against a global database, automatically blocking high-risk attempts before the login is completed. https://auth0.com/docs/customize/actions/use-cases
Do Auth0 Actions support public and private npm packages?
Auth0 Actions supports Public NPM packages, but it doesn’t support using Private NPM packages. It also supports Actions Modules which is a way to code, share, and reuse functions between different Actions. https://auth0.com/docs/customize/actions/manage-dependencies https://auth0.com/docs/customize/actions/modules/actions-modules-overview
How do Auth0 Actions improve extensibility?
Auth0 Actions improve extensibility as a pro-code solution. Users can use custom code to allow variations of workflows outcome based on contextual information. https://auth0.com/docs/customize/actions/actions-overview https://auth0.com/docs/customize/actions/use-cases
How do I migrate from Auth0 Rules and Hooks to Actions?
Migrating from Rules and Hooks to Actions involves identifying your existing logic and refactoring it into the Actions trigger-based system. Auth0 provides dedicated migration guides and a visual editor to help developers transition their code. https://auth0.com/docs/customize/actions/migrate
What are Auth0 Actions?
Auth0 Actions are serverless functions that allow developers to customize and extend the Auth0 platform during the authentication and authorization process. Developers can build custom logic—such as real-time fraud checks, progressive profiling, and step up authentication—directly into the login flow. https://auth0.com/docs/customize/actions/actions-overview
How do Auth0 Actions replace legacy Rules and Hooks?
Auth0 Actions serve as the modern, Node.js-based successor to legacy Rules and Hooks, offering a more robust and maintainable extensibility model. Actions enable teams to implement complex user data enrichment and security policies with higher performance and easier debugging throughout the identity lifecycle. https://auth0.com/docs/customize/actions/actions-overview https://auth0.com/docs/customize/actions/migrate
