Verifying rules helps isolate the source of authentication issues in Auth0. Review rule configurations, catch potential errors, and use debugging tools to ensure rules execute correctly.

NOTE: The End of Life (EOL) date for Rules and Hooks is November 18, 2026, and they are no longer available to new tenants created after October 16, 2023. Existing tenants with active Hooks will retain Hooks product access through the end of life.

Auth0 highly recommends using Actions to extend Auth0. Actions offers access to rich type information, inline documentation, and public npm packages, and can connect external integrations that enhance the overall extensibility experience. To learn more about what Actions offer, refer to Understand How Auth0 Actions Work.

To assist with migration, guides are available to help migrate from Rules to Actions and migrate from Hooks to Actions. Additionally, a dedicated Move to Actions page that highlights feature comparisons, an Actions demo, and other resources is available to support the migration journey.

IPv6 addresses are exposed in Auth0's public endpoints (for example, travel0.us.auth0.com). If a request arrives from a machine that supports IPv6, then the context.request.ip property will contain an IPv6 address. For manual IP address manipulation, the ipaddr.js@1.9.0 library is recommended.

What checks are needed to verify rules during troubleshooting?

Rule failures often cause authentication issues. Perform the following checks to determine whether rules are causing the issue.

• Turn rules off and determine whether the issue still occurs.
• Verify that the rules catch all possible errors that might return. Uncaught errors cause failures.
• Verify that the rules call the callback function only once for each logical branch in the code.
• Add console.log() statements to the rules to debug and check the state (for example, console.log("output = " + some_variable);).
• Select Debug Rule in the Dashboard to view the output from the console.log statements.
• View the output in Actions Real-time Logs to obtain more information about the execution of the rules.

NOTE: Review the Monitoring page for more details on each log event that can assist with troubleshooting.
