Developing case management applications with the REST protocols
You can use the REST protocols to incorporate IBM® Case Manager features in your custom application. You use the IBM Case Manager REST protocol to access case-specific objects. You use the Process Engine REST Service to access workflow-related aspects of tasks.
The REST protocols are provided for compatibility with previous releases of IBM Case Manager. If you are developing a new custom case management application, use the JavaScript APIs that are provided with IBM Case Manager and IBM Content Navigator.
