FHIR Messaging Overview

The Pan-Canadian eReferral-eConsult Messaging Interoperability Specification, enables a bi-directional exchange of information about referral requests, appointments, referral related tasks and communications between two trusted systems using FHIR messaging, and is the basis of integrations that connect systems participating in eReferral-eConsult related exchanges to one another.

In FHIR messaging, a message is sent from a source application to a destination application when an event happens. A message is a Bundle resource of type message, that conforms to specific rules.

For details, see HL7 FHIR Messaging documentation.

A popular way to transfer messages is using HTTP based $process-message FHIR operation, that includes RESTful interactions. For details, see $process-message operation definition.
