I looked at the URL
http://www-10.lotus.com/ldd/lcwiki.nsf/dx/9.0_Using_the_API for documentation for the IBM Connections API. I need to get more details on how I can use the API to get other attributes of an activity. For example, in addition to the title, body text, attachment(s), I also need the user defined fields (label and value). Does anyone know of any other reference materials that explain how to get the information (particularly the user defined fields)?
