Communication
$communication-create

Communication $communication-create

post/Communication/$communication-create
Page View

This resource contains messages, notifications, and alerts sent to patients or other parties. Each communication entry contains the content, sender, recipient, status, and date information.

You can review or retrieve communications with FHIR® passthrough.

Supported fields and schema examples

We support any valid FHIR® field. However, we only display fields we’ve defined in our schema, which are usually based on what’s included in the U.S. Core profile. We recommend relying on U.S. Core requirements.

Our schema examples show the shape and possibility of each FHIR® resource; they aren’t code for real-time API calls. We don’t currently recommend copying and pasting these schema examples for your API calls. Consider reviewing FHIR® API actions for realistic examples for particular use cases.

$communication-create

Send a new communication record (e.g., a message to a provider's inbox) to the destination system. The Patient resource is optional.
