Verwenden Sie diesen Endpunkt, um den Kunden genau zu zeigen, was ihnen bei einem Upgrade oder Downgrade ihres Abonnements berechnet wird, wodurch die Transparenz verbessert und Supportanfragen reduziert werden.

​
Anwendungsfälle

  • Checkout-Bestätigung: Zeigen Sie die anteilige Gebühr an, bevor Kunden eine Planänderung bestätigen
  • Preisrechner: Erstellen Sie Upgrade-/Downgrade-Rechner in Ihrer Anwendung
  • Kunden-Selbstbedienung: Ermöglichen Sie es Kunden, Tarifoptionen mit genauen Preisen zu erkunden
  • Rabattvalidierung: Zeigen Sie an, wie gestapelte Rabattcodes die Preisgestaltung bei der Planänderung beeinflussen
Sie können discount_codes (ein Array von bis zu 20 Codes, in der Reihenfolge angewendet) in der Vorschauanforderung einfügen, um zu sehen, wie die gestapelten Rabatte die sofortige Gebühr und die neue Tarifpreisgestaltung beeinflussen, bevor Sie die Änderung vornehmen. Das einzelne discount_code Feld ist veraltet, wird aber aus Gründen der Abwärtskompatibilität weiterhin unterstützt; wir empfehlen discount_codes für die Zukunft.

​
Antwortfelder

Die Vorschau-Antwort enthält:
FeldBeschreibung
immediate_chargeDie Gebühr, die sofort erstellt würde, einschließlich Posten und Zusammenfassung
new_planDas vollständige Abonnementobjekt, das zeigt, wie es nach der Planänderung aussehen würde
Der immediate_charge.summary enthält den Gesamtbetrag, der berechnet werden würde. Verwenden Sie dies, um Ihren Kunden die Preise anzuzeigen, bevor sie die Planänderung bestätigen.
