Thanks for posting- and great question!
We were just talking about this at Igloo HQ- The first step is over the next few weeks we are revamping and improving the existing documentation to make it more platform and language agnostic, and more thoroughly detailed.
The next step after that is to create a Postman Collection. We will at minimum have the important stuff- Authentication, Blog/Calendar/Wiki/Forum/Object, etc, and build it from there. We definitely recognize the value in having that Collection available, and I have used Postman a few times myself!
The format it is currently published in, is the wonderful industry-standard Slate API documentation library, but our own custom in-house version.
