## Document Retrieve

To retrieve a document from CDR, HTTP GET is used to retrieve it from its physical location URL. The response will be a FHIR document in the form of a bundle resource with type set to "document". In order to be FHIR conformant, the first resource in the bundle must be a  composition resource that contains the document metadata. Please see the workflow diagram below.
