Goon IM API - RESTful Services
The IBM Security Identity Manager APIs are complex and require a detailed understanding of both Java and the ISIM data model for development to take place.
IBM have introduced a SOAP based Web Services API which does improve integration options but is still complex and requires a Web Services client to be generated.
GoonIMAPI is a new simple but powerful way of integrating clients and applications with ISIM using RESTful Services. The GoonIMAPI services are called using standard HTTP methods (GET, POST, PUT and DELETE) and are by far the simplest way for developers to integrate with ISIM: -
"REST has had such a large impact on the Web that it has mostly displaced SOAP- and WSDL-based interface design because it's a considerably simpler style to use."
The GoonIMAPI hides the complexity of the ISIM API and allows you to focus on presentation and rapid integration.
