[galaxy-dev] Using API to identify all datasets that were part of a workflow?

Hello, I'm still relatively new to galaxy. I'm trying to use the API to identify the string of jobs/datasets that were created as part of executing a workflow. So far as I can tell, the API gives me the ID of the job, which corresponds to one step in the workflow. Each of these has inputs/outputs. I can walk outwards and try to connect any other jobs that happen to use one of these files as an input or output; however, I am not seeing any key that provides a more direct indication that a set of steps was executed as part of a given workflow. Am I missing something? Thanks in advance, Ben
