Messaging & Communications
FHIR supports messaging workflows through the Communication resource. This resource allows your system to manage message content and metadata in a format independent of its medium (email, sms, chat,etc.).
These Communications can also be structured to support a variety of use cases, including:
- Threaded messages
 - Asynchronous encounters
 - Omni-channel messaging
 - Real-time notifications using Websockets
 
Check out our Contact Center Demo for an in-depth example of a provider messaging app.
