pubsubTopic property

The Pub/Sub topic that notifications of changes are published on.

Supplied by the client. The notification is a PubsubMessage with the following fields: * PubsubMessage.Data contains the resource name. * PubsubMessage.MessageId is the ID of this notification. It is guaranteed to be unique within the topic. * PubsubMessage.PublishTime is the time when the message was published. * PubsubMessage.Attributes contains the following attributes: * action: The name of the endpoint that generated the notification. Possible values are StoreInstances, SetBlobSettings, ImportDicomData, etc. * lastUpdatedTime: The latest timestamp when the DICOM instance was updated. * storeName: The resource name of the DICOM store, of the form projects/{project_id}/locations/{location_id}/datasets/{dataset_id}/dicomStores/{dicom_store_id}.

• studyInstanceUID: The study UID of the DICOM instance that was changed. * seriesInstanceUID: The series UID of the DICOM instance that was changed. * sopInstanceUID: The instance UID of the DICOM instance that was changed. * versionId: The version ID of the DICOM instance that was changed. * modality: The modality tag of the DICOM instance that was changed. * previousStorageClass: The storage class where the DICOM instance was previously stored if the storage class was changed. * storageClass: The storage class where the DICOM instance is currently stored. Note that notifications are only sent if the topic is non-empty. Topic names must be scoped to a project. The Cloud Healthcare API service account, service-@gcp-sa-healthcare.iam.gserviceaccount.com, must have the pubsub.topics.publish permission (which is typically included in roles/pubsub.publisher role) on the given Pub/Sub topic. Not having adequate permissions causes the calls that send notifications to fail (https://cloud.google.com/healthcare-api/docs/permissions-healthcare-api-gcp-products#dicom_fhir_and_hl7v2_store_cloud_pubsub_permissions). If a notification can't be published to Pub/Sub, errors are logged to Cloud Logging. For more information, see Viewing error logs in Cloud Logging.
