off topic, sorry: Looking at the docs and I don't find a quick answer. I really want an API client that will do OAuth and handle token refresh, and I haven't found one. The use case is that (obviously) I control the redirect URI, so I'd like to map it back to client (some kind of proxy that I run and make external with all of the requisite DNS and TLS) or maybe via a hosted service (which I'm willing to accept for the convenience.)

I haven't used postman or insomnia in a while since they went to the cloud, so I could just be missing it, but that's also a non-starter for me.
