Unter Änderungsereignis finden Sie eine detaillierte Aufschlüsselung der Änderungen in Ihrem Konto. Bei der Berichterstellung zu einem Erstellungsvorgang werden alle neuen Feldwerte zurückgegeben. Bei Berichten zu einem Aktualisierungsvorgang werden sowohl neue als auch alte Werte zurückgegeben. So erhalten Sie ein vollständiges Bild der einzelnen Änderungen.
Außerdem wird der für die Änderung verwendete Clienttyp (z. B. API oder Webclient) angegeben und der Nutzer, der die Änderung vorgenommen hat, vorausgesetzt, dass diese Informationen auch im Änderungsverlauf des Webclients sichtbar sind.

Abfrage
Die Liste mit Änderungen muss nach Datum gefiltert werden. Der Zeitraum muss innerhalb der letzten 30 Tage liegen.
Die Abfrage muss außerdem eine LIMIT-Klausel enthalten,die die Ergebnisse auf maximal 10.000 Zeilen beschränkt. Wenn Sie an mehr als 10.000 Ergebnissen interessiert sind,notieren Sie sich den Zeitstempel des letzten Eintrags im zurückgegebenen Ergebnissatz. Legen Sie dann den Zeitraum in der folgenden Abfrage so fest, dass er nach diesem Zeitpunkt beginnt. Sie können dann dort fortfahren, wo Sie aufgehört haben.
Es kann bis zu drei Minuten dauern, bis eine Änderung in den Ergebnissen des Änderungsereignisses sichtbar wird.
Das folgende Beispiel zeigt, wie Änderungsereignisse abgerufen und verarbeitet werden. Dazu gehört, zu ermitteln, wer die Änderung vorgenommen hat, welchen Clienttyp sie für die Änderung verwendet haben und wie die alten und neuen Werte der einzelnen Felder in der Änderung aussehen:

Beschränkungen
Ein Änderungsereignis enthält möglicherweise nicht jede Zeile aus dem Änderungsverlauf im Webclient. Für eine ähnliche Ansicht wie den Änderungsverlauf können Sie stattdessen die Änderungsstatusressource verwenden.
Die Änderungsereignisressource ist dazu gedacht, die Details einer einzelnen Änderung aufzuschlüsseln. Sie können Daten abrufen, z. B. bestimmte geänderte Feldwerte, wer die Änderung vorgenommen hat und welcher Clienttyp für die Änderung verwendet wurde. Es gibt jedoch nicht für alle Änderungen an Ihrem Konto einen entsprechenden Eintrag.
Zu den wichtigen Clienttypen, die ihre Änderungen zur Verwendung mit Änderungsereignissen aufzeichnen, gehören:
- Google Ads API
- Google Ads-Webclient
