Trying to get the auth code using
(yes, identity[email] is displayed here incorrectly, is is URL-encoded in the request)
results in an HTTP 500 error and a patreon error page that is not helpful at all. I haven’t changed anything on my side, and besides some user reports indicating changed API URLs, no official information can be found.
I know API v2 is in beta, but that cannot mean that there is no information flow at all! My users have access on some data based on that auth, so you are basically shutting my “business” down.
