## Audit Event Service: Query API

Die **Query API: AuditEvent** ermöglicht den Abruf protokollierter Ereignisse und Zugriffe auf das Aktenkonto eines Versicherten im ePA-Aktensystem.

### Einsatzbereich

Das ePA-FdV oder das ePA-Client-System einer Ombudsstelle nehmen Einsicht in die Protokolldaten zum Zwecke der Datenschutzkontrolle für den Akteninhaber.

### Nachricht

Die Nachricht zum Abruf von Protkolldaten wird als HTTP GET-Anfrage an den Audit Event Service gesendet, um eine Liste von *Audit*-Ereignislisten abzurufen.

#### Auslösung

Wenn das ePA-FdV oder ePA-Client-System eine Suche über protokollierte Ereignisse und ePA-Zugriffe durchführen und dazu die korrespondierenden **AuditEvent**-Ressourcen ermitteln möchte, sendet es eine **Query API: AuditEvent**-Nachricht an den Audit Event Service.

#### Resource API

Anfragen an die *AuditEvent*-Ressource werden über die RESTful API mittels HTTP GET-Anfragen durchgeführt werden. Dabei können spezifische Suchparameter genutzt werden, um die Anfragen zu verfeinern.

Bei Anfragen an die Query API für die *AuditEvent*-Ressource wird die Antwort als ein FHIR Bundle des Typs *searchset* zurückgegeben. Dieses Bundle enthält eine Sammlung von Einträgen, die jeweils eine Instanz der *AuditEvent*-Ressource enthalten.

Der Audit Event Service MUSS die Suchparameter, die in dem
*[CapabilityStatement](./CapabilityStatement-epa-audit-event-server.md)*mit dem Namen
*EPAAuditEventServer*verarbeiten können.

Die Standardsortierung des Audit Event Service MUSS anhand des Attributs
*recorded*in absteigender Reihenfolge, sodass die neuesten Daten zuerst angezeigt werden.
#### Instance API

Um spezifische Details zu einem einzelnen Ereignis mittels der RESTful API zu erhalten, wird die **AuditEvent Instance API** verwendet, indem eine HTTP GET-Anfrage an den Endpunkt */AuditEvent/[id]* gestellt wird.

   
```

#### Verarbeitung

Der Audit Event Service verarbeitet die Anfrage, um die **AuditEvent**-Einträge zu ermitteln, die den angegebenen Suchparametern entsprechen. Darüber hinaus gibt er einen zur Verarbeitung passenden HTTP Status Code sowie ein [FHIR Bundle](https://hl7.org/fhir/R4/bundle.html) der passenden [AuditEvent](./StructureDefinition-epa-auditevent.md)-Ressourcen zurück.

### Sicherheitsanforderungen

Generelle Sicherheitsanforderungen werden [hier](./privacy-security.md) festgehalten.
