Facing the issue on FHIR

I am facing the Authorization issue. Can anyone please help me?

On the 2nd screenshot, Have you read through the documentation? You are not sending anything in your authorize request with that postman request. Read the documentation to learn how to craft an authorize request.

On your first swagger request, you should turn on the debug logging and check your apache error logs. Most likely you’ve misconfigured your application registration. There are numerous forum threads of people asking these same questions. You’ll find many of your answers there.
