201709 Consumer Centered Data Exchange Implementation Notes for test.fhir.org

Acquiring the JWT

you get the JWT (to use test.fhir.org as the target) by:

 GET http://test.fhir.org/r3/$jwt?source=[uri]

Where [uri] is the address of the source system. Source is a mandatory parameter, though it does not make any difference to test.fhir.org

this returns a 200 OK with a body content type of application/jwt:

Consent

Use this consent resource as the base for authorization (post it to the server):

<Consent xmlns="http://hl7.org/fhir"> 
  <id value="1"/>
 <status value="active"/>
 <patient>
   <reference value="Patient/example"/>
 </patient>
 <policyRule value="http://hl7.org/fhir/ConsentDefinition/simple-oauth"/>  
 <except>  
   <type value="permit"/>
   <action>
     <coding>
       <system value="http://hl7.org/fhir/consentaction"/>
       
     </coding>
   </action>
   <class>
     <system value="http://smarthealthit.org/fhir/scopes"/>
      
   </class>
 </except> 
</Consent>

Authorization

This is what you post to the server as a body to the $authorize routine (this time in json):

{
 "resourceType" : "Parameters",
 "parameter" : [{
    "name" : "duration",
    "valueDuration" : {
      "value" : "3",
      "system" : "http://unitsofmeasure.org",
      "code" : "mo"
    }
  }, {
    "name" : "jwt",
    "valueString" : "{your packed JWT}"
  }  
 ]
}
