Like Curtis, I was able to find the how but not the where. There are ways to pull the data from within SCCM so it's out there somewhere, but I'm not sure if it's in flat files (there are a bunch of logging files for SCCM - our own Patch Manager pulls and uses some of them) or if it's in the database itself somewhere.
Either way it's technically possible for us to build an integration, one is just more expedient (flat files)
