The Object API lets you see, use, and manipulate the GroupWise information store from outside GroupWise. With the Object API, you can create your own client application. It provides access to the GroupWise Address Book, documents, mail messages, appointments, tasks, notes, and phone messages. It supports OLE Automation, which is an industry standard for interfacing applications. It is simple to use with languages such as Delphi and Visual Basic, and can also be used with C/C++ languages.
