The SDKs and code samples are targeted to programming languages and software platforms, not hardware platforms, since hardware platforms often provide multiple options. Additionally, on a hardware board, it's going to depend on what you have connected to it and whether the login process can even be completed on-device or if it needs to be proxied through an app or website.
We'll definitely put this on our list of possible blog post topics, though. It would be interesting to explore in more depth.
There's a getting started guide, example sketches, and a library that will take care of some of the api calls for you!
Hope it helps!
