JavaScript API for client-side human service development
Use the following reference information to learn more about the client-side JavaScript system variables that are available in IBM Process Designer for client-side human service development.
These variables are populated when the client-side human service is run and reflect the state of the system at that point in time. These variables are not meant to be updated within the client-side human service.
Additional system data is available by calling a service that retrieves the system variables that you are interested in, and returning them back to the client-side human service.
