You can also request additional attributes with the relatedItemAttributes option. This option can be a CSV string of names or a list of names. You can request the following standard attributes:
request
requester
description
activityName
If you request an attribute name that is not on this list, Waveset assumes that it is an arbitrary workflow variable, and the value will be returned if it exists in the work item. Common variables found in the standard workflows include:
accountId
objectType
objectName
diagramLabel
