Im Vergleich zur Methode GetTripOptions bietet die Methode GetBulkTripOptions folgende Vorteile:
- Ermöglicht eine effizientere Befüllung des Google-Cache, da weniger Anfragen erforderlich sind und die Upstream-APIs von Betreibern besser berücksichtigt werden. Partner können diese APIs verwenden, um die Daten selbst abzurufen.
- Partner mit einer vorgegebenen Anzahl verfügbarer Fahrten können ihre Daten einfacher bereitstellen, ohne dass eine detaillierte Überprüfung der Reiseroute erforderlich ist.
- Auch anspruchsvollere Partner erhalten eine Liste bekannter Reisepläne, um den Abgleich von Partnerbestand und von der Google-Routing-Engine erstellten Reiseplänen zu maximieren. So werden Partnerpreise für möglichst viele Reisepläne angezeigt.
- Ermöglicht die Aufnahme von Routen, die Google noch nicht anbietet, um die Google-Routing-Engine in Zukunft möglicherweise besser an das Partnerinventar anzupassen.

Typische Szenarien
Wir stellen uns die folgenden Szenarien mit bestimmten Anfrageformen für die API vor:
Für weniger technisch versierte Partner wird nur ein
market_datebereitgestellt. Diese Partner können eine aufmarket_datebasierende Abfrage für ihre Upstream-Daten verwenden und alle Ergebnisse zurückgeben, die unserem Datenformat zugeordnet sind. Google kann die Ergebnisse filtern, sodass nur die erwarteten Reisepläne angezeigt werden.Für technisch versiertere Partner ist es sinnvoll, sowohl
market_dateals auchknown_itinerariesbereitzustellen. Der Partner kann eine detaillierte Suche in internen Datenbanken durchführen, um die erwarteten Reisepläne genau zu bepreisen. Alle angefordertenknown_itinerarieswerden Nutzern angezeigt. Partner können so die Anzahl der Reisepläne maximieren, für die ihr Preis und Buchungslink angezeigt werden. Partner haben weiterhin die Möglichkeit, zusätzliche Routen zurückzugeben, damit Google ihr eigenes (beworbenes) Inventar besser abgleichen kann.
Fehlerberichte
Fehler sollten für jede Fahrt einzeln gemeldet werden. Die bevorzugte Antwort ist daher BulkTripOptionsResult (HTTP 200), die Fehler pro Fahrt in bulk_trip_options_result.itinerary_responses[i].trip_options_error angibt. Wenn die gesamte Anfrage unerwartet fehlgeschlagen ist, verwenden Sie bulk_trip_options_error mit BulkTripOptionsErrorType.INTERNAL_ERROR (HTTP 500).
Weitere Informationen finden Sie unter TripOptionsErrorType.
Informationen zum Zurückgeben von Statuscodes in HTTP-Antworten finden Sie unter Statuscodes und Fehlerbehandlung.
Anmerkungen
MarketDate.departure_date gibt einen Kalendertag an. Um die Operator-APIs besser abzugleichen, wird hier die Zeitzone am Ursprung verwendet. SegmentKey gibt jedoch weiterhin die Ein- und Ankunftszeiten in UTC an, um die Konsistenz mit GetTripOptions zu wahren.
