Thanks for responding.
I have the OAuth stuff working using the code flow. It only returns a “code”. I assume that is the “token” you are referring to? It does not return a “refresh_token” when I use the code flow for OAuth - do I need to take more steps?
When I connect to the API, it sounds like I just use this returned “code” or “token” and that will allow the API to know that payments go into this customer’s account and the app fees go into mine?
