Thanks for including the response header. It looks like no token was provided in the request, resulting in a 401.

I'm a bit confused as I thought this request was being used to retrieve an access token.. i am providing a client id and secret, where should i be obtaining the token from to provide in this request?

The request you posted is for the Patient resource. The authorization process [1] should be followed to obtain the token.

After working with someone else we found the issue was the client secret we were passing was incorrect...
