UAPI query messages are POSTed to their recipients using the $process-message operation.
The $process-message operation SHALL contain a single content parameter consisting of a FHIR message (a Bundle containing a MessageHeader resource).
Notes:
Because the Process Message operation does not use the Parameters resource, the “content” parameter is always the body of the HTTP message.
The async and response-url Process Message parameters are not to be used when exchanging UAPI messages.
See Error Handling for instances where the request cannot be processed in part or in whole.
