Hi, I am implementing an authorization from Cerner to my desktop application.
The workflow is user clicks on a link and authorizes itself using its credentials.
And redirect to a URL where its auth_code is used for retrieving of access_token.
I successfully retrieved the access_token.
Now I want to retrieve data from Cerner, using this access token.
I am using the Spring rest template to call Cerner's data endpoints.
But problem is that I need to validate the token as after some time the access_token expires.
So before every request to Cerner, I want to validate the access_token.
Is there is any way I can validate access_token?
I have gone through this post from google group.
but in metadata there is no endpoint for /tokeninfo.
I am using fhir dstu2 specification and cerner sandbox for development.
