Direct Messaging

Direct Message

If your organization's account is set up with Direct Secure Messaging (see https://directtrust.org/what-we-do/direct-secure-messaging) support enabled in Health Gorilla then you can send and receive Direct Messages using DirectMessage resource. A message is a composite object that can contain a sender and recipients, a subject, a message body and attachments. Users may send messages to (and receive from) any Direct address.

A DirectMessage can contain arbitrary files as well as DiagnosticReport, RequestGroup, DocumentReference and ReferralRequest resources as attachments.
