Has anyone successfully integrated Appian with Adobe PDF Services?

Can you shed some lights on the use case?

We successfully integrate with Adobe Sign (our integration is largely manual, iirc it was set up before the more recent / more automated version became available).  It works pretty well from within Appian, though it's a giant pain-in-the-you-know-what doing certain Template management / upkeep items on our remote templates stored in the Adobe Sign system.  I can share more details on this with you if it's actually what you're after.
