Ooh. That’s a question better answered by the Kobo folks themselves. (I actually work for OpenFn, a group that focuses on integation—connecting Kobo to other systems/databases/etc—and I am not 100% sure about differences across those servers/plans off the top of my head.)
That said, this post seems to suggest that the humanitarian server has a similar (if not the same) API: KoBo API examples, using new KPI endpoints
Have you tried accessing the same endpoints from your particular implementation’s baseURL? For what it’s worth, we haven’t run into any clients who don’t have access to that API before and we work with lots of folks in the health and humanitarian sectors, so my guess is that it’s the same across the board. Hope this is a helpful start.
