# NotificationUpsertRequest

Model ID: `NotificationUpsertRequest`

HC transport shape for creating/updating a patient notification.

All fields are optional: a create may carry the full shape, while the
app's "mark read" sends only ``{read: true}`` via PUT. The service layer
merges partial updates over the existing FHIR Communication
(read-modify-write), so a partial body never wipes stored fields.

Type: `object`
