Scripting API

AM provides the following functionality and artifacts for scripting:

(Authentication trees only)

Access data in request headers, shared state, and user session data.

Access the authorization state data, the information pertaining a session, and the user’s profile data in authorization policies.

Customize OAuth 2.0

Extend authorization server behavior with the OAuth 2.0 plugins:

Access token modification Modify the key-value pairs contained within an OAuth 2.0 access token.
Authorize endpoint data provider Return additional data from an authorization request.
Scope evaluation Evaluate and return an OAuth2 access token’s scope information.
Scope validation Customize the set of requested scopes for authorize, access token, refresh token and back channel authorize requests.
OIDC user info claims Map scopes to claims and data for OpenID Connect ID tokens.

Access HTTP services

Configure the parameters for the HTTP client object in any server-side script.

Debug logging

Add debug logging to any server-side script.

Token exchange

Add may_act claims to OAuth 2.0/OpenID Connect exchanged tokens.

Scripted module API

(Deprecated: Authentication chains only)

Access authentication state data, user profile data, request data, and information gathered by client-side scripts.

Reference substituted properties in scripts

The systemEnv binding, available to all AM script types, provides the following methods shown with their Java signatures:

String getProperty(String propertyName);
String getProperty(String propertyName, String defaultValue);
<T> T getProperty(String propertyName, String defaultValue, Class<T> returnType);

where:

propertyName refers to a configuration expression identifier without the ampersand and braces.

The propertyName always starts with a prefix; for example, script.my.variable. The default prefix is script. To change the prefix in the AM admin UI, go to Configure > Global Services > Scripting > Secondary Configurations > Script Type > Secondary Configurations > Engine Configuration > Property Name Prefix, and set the prefix without the trailing .

Make sure the propertyName is specific enough to distinguish it from all other configuration expressions.
defaultValue is a default value to use when no configuration expression identifier matches propertyName.

It must not be null.
returnType is a fully qualified Java class name; one of the following types:
- String
- Integer
- Double
- List
- Map
- Boolean

The following Scripted Decision node examples use the default property name prefix:
