Locating the HCL Link connections

Each Link connection is available as a catalog in the Service Definition dialog, in the first category Select from Service Catalog.
Note: The actions are configured using HCL Link. For more information, see Defining Link artifacts.

Each service has its own unique inputs and outputs as defined by Link. Map the inputs and outputs from your form to the selected service. Then setup how to trigger the service (for example: a field onChange event, button click, etc).
