InterSystems FHIR Server does not support accepting an OAuth 2.0 access token via request URL parameter.

For the FHIR Server, the only supported vehicle for the access token is the HTTP Authorization header ("Bearer", plus space, plus the token string).

Hi Paul,

I have come across same issue. I can successfully generate an access token as you can se in the following image:

And I am also supplying the access token as Bearer token for authorization as in the image below:

But, I am still getting the '401 Unauthorized' error.

What shall the cause be?

Hi Piyush,

Is the token an opaque token, or is it a JWT? FHIRServer currently does not handle opaque tokens.

Best regards,

Paul
