Managing mapping rules

Edit online

The mapping rules are JavaScript code that run during the authentication flow. Use the rules to customize the authentication service and the one-time password generation, delivery, and verification.

Before you begin

Attention: Use extreme care when you replace mapping rules. Any change that you make to a mapping rule can affect the entire runtime environment. Always export a copy of the original rule you plan to replace so that you have a backup copy.

About this task

You can customize several components through JavaScript code. For example, you can customize the Authentication Service to modify the content of user credential by modifying the AuthSvcCredential mapping rule.

The JavaScript code is run by the Rhino JavaScript engine. Your JavaScript code must conform to JavaScript 1.7. Your JavaScript code is not run under a browser environment. Therefore, you cannot use objects and functions that are available only in a browser environment. You can, however, use standard JavaScript objects (such as Math) and functions (such as parseInt). In addition, your JavaScript code can use allowed Java classes, which you might need so that you can use operations that are not supported by standard JavaScript functions. You can find the list of these Java classes at JavaScript Allowlist. To find out more about using Java classes in JavaScript, see the Rhino documentation https://developer.mozilla.org/en/docs/Rhino.
