Hi @Steven for the most part that is the complete list when viewing Help > API Docs. It is typically up to date within a couple weeks in conjunction with what's on GitHub, but probably wouldn't hurt to check in both places. The API is being enhanced all the time. One of the most recent additions maybe 2 weeks ago was the ability to add a cloneid to the addnetwork function to be able to clone existing networks into new ones, which translates back to the new copyFromNetworkId parameter when looking at Help > API Docs.
So if you haven't already bookmarked, in addition to Help > API Docs, I'd check out:
https://github.com/meraki/dashboard-api-python
and
https://github.com/meraki/dashboard-api-python/blob/master/meraki.py
and just to show an example of that recent addition:
