DISCLAIMER: Not endorsed by, affiliated with, or sponsored by Ivanti, Workato, Zapier, BMC Remedy.  Any use of the software product names is descriptive of the fact that we have experience with the mentioned ITSM and CRM products Although the term Integration Platform as a Service was invited in 2011, the first such services didn't surface in the Ivanti Neurons for ITSM/ITAM world until about 5 years ago with Zapier, a company that provides integrations for web applications. At that time API was, and to a degree still is, very difficult and time-consuming to implement and maintain, so Zapier was touted as a great solution and possibly the future of integrations. However, a lack of features (at least in the Ivanti universe) as well as cost were the main factors for its fizzling out. I have to say that I was really impressed by the Workato integration that Ivanti demonstrated on a recent show-and-tell webinar.
