How does the authentication server respond asynchronously to my authentication request, when the client is the browser?
The (always incomplete) answer is that the user (me human, not the client, being the browser) need to provide the “callback” via the Okta application panel shown below:
Does the path
http://localhost:3000/users/callback have to exist - or is the “substring”
http://localhost:3000 the only information used by Okta SDK?
In other words, is the behavior described as “the auth server provides the requested data to localhost at port 3000” and it is the SDK responsible to install a listener at port 3000, which (listener) delivers the data to my app?
