Eine ID, die Ereignissen zugewiesen wird, die im Rahmen einer einzelnen Sitzung mit zugehörigen Ereignissen auftreten. Kann zum Konsolidieren von Ereignissen verwendet werden.
string Beispiel: „CjY5Y3VKaTZwR3o4Y19YbTVfMF...“
eventId
Eine mit dem Ereignis verknüpfte ID.
Verwenden Sie ihn mit dem GenerateImage-Befehl, um das Kamerabild herunterzuladen, das sich auf dieses Ereignis bezieht.
Ein Objekt, das Ressourcen angibt, die möglicherweise ähnliche Aktualisierungen wie dieses Ereignis haben. Die Ressource des Ereignisses selbst (aus dem resourceUpdate-Objekt) ist immer in diesem Objekt vorhanden.
