Tokens assign names to low-level events, such as "save a file" and "send mail," and allow you to use tokens to operate as programs. While a C3PO lets you extend GroupWise objects, and the Object API lets you see and manipulate the GroupWise information store from outside GroupWise, tokens let your solution command the GroupWise client from DLLs and DDE scripts using the Third-Party Handler. You can also use tokens to create Visual Basic executables that users can run from the client interface.
See the GroupWise Tokens SDK.
