I’m having trouble setting up an Okta native app that uses pkce. I have a .net core 2 web api that is set up to accept jwt tokens per the documentation. In the Okta app, I have set up a native application that uses com.oktapreview.dev-169299:/callback as the login redirect uri. When we construct the call to the authorization url, it returns a session token in a json object after the login. If I put in a redirect_uri that I know will 404, I can get the code from the url and supply that to the /token endpoint in a post, but that returns
“error_description”: “PKCE verification failed.”
Is there a way to test the flow through postman or a web browser?
Also, is there a tutorial that shows how to set up the client in c# (for xamarin)?
