I've received developer tokens from my institution and I'm trying to follow the steps at OAuth2 - Canvas LMS REST API Documentation, but I don't quite know how to work it.
I'm developing on .netcore 2.0 and I can't open an authentication web page for the user to select. This will be all done remotely through an API wrapper. I always get back the login url, <Domain>/login/canvas, instead of http://www.example.com/oauth2response?code=XXX&state=YYY which is supposed to be redirected to. Help would be appreciated. This is a "native" app and so I'm using the string "urn:ietf:wg:oauth:2.0:oob" as the redirect_uri.
