Wiederkehrende Zahlungen

Zahlungen Bezahlfunktionen Wiederkehrende Zahlungen

Novalnet selbst bietet eine Abonnementsverwaltung als eine unserer Kernkompetenzen an. Wenn Sie jedoch selbst wiederkehrende Zahlungen in Ihrem Webshop verarbeiten und spätere Zahlungen nach einem Zeitplan einreichen wollen, können Sie unser serverseitiges Tokenisierungsverfahren einsetzen.

Um mehr über Tokenisierung zu erfahren, sehen Sie sich dies hier an >>Link<<

Die Buchungen können für wiederkehrende Transaktionen durchgeführt werden, indem man das Token einsetzt, welches bei dem Aufruf für die erste Abonnementszahlung erzeugt wurde.

Unterstützte Zahlungsarten

Kredit- / Debitkarte
SEPA-Lastschrift
SEPA-Lastschrift mit Zahlungsgarantie
Lastschrift ACH
PayPal
Apple Pay
Google Pay

Um das Tokenisierungsverfahren für die Zahlungsart PayPal zu verwenden, müssen Sie die Funktion zur Abbuchungsvereinbarung bei PayPal aktivieren

Generierung eines Tokens

Befolgen Sie die Schritte unten, um den Tokenisierungs-Prozess anzustoßen, die Rückmeldung zu identifizieren und das Token zu speichern.

Schritt 1: Benachrichtigen Sie den Novalnet-Server, um ein Token zu generieren

Übergeben Sie den Parameter transaction.create_token in Ihrem Zahlungsaufruf (auf der Grundlage Ihres Einbindungstyps), um ein Token anzulegen. Sehen Sie sich die Schritte unten an, je nach Ihrem Einbindungstyp,

Wenn Sie die gehostete Zahlungsseite einbinden, sehen Sie sich bitte dies an >>Link<< zu den Parameterdetails.
Wenn Sie die direkte Anbindung an die API verwenden, sehen Sie sich bitte dies an >>Link<< zu den Parameterdetails.

Ausführen

Schritt 2: Speicherung des Tokens nach einer erfolgreichen Rückmeldung (für die zukünftige Verwendung)

Das Token wird nur angelegt, wenn der Zahlungsaufruf in dem oben erwähnten Schritt 1 erfolgreich durchgeführt wurde. Überprüfen Sie dazu in der Rückmeldung zu Ihrer Zahlung, ob der Wert für den Parameter result.status SUCCESS ist .

Für die zurückgemeldeten Fehler überprüfen Sie die Fehlerdetails bitte anhand des Parameters result.status_text. Um mehr über die Statuscodes und ihre Bedeutung zu erfahren, sehen Sie sich bitte dies an >>Link<<.

Bei einer erfolgreichen Rückmeldung finden Sie das neu generierte Token in der Rückmeldung im Parameter transaction.payment_data.token, welches Sie in Zukunft verwenden können.

Führen Sie Folgezahlungen aus, indem sie Tokenisierung einsetzen (ohne Interaktion mit dem Kunden).

Um das Token auf der Grundlage Ihres Geschäftsmodells zu verwenden, muss das Token zuerst angelegt werden (wie beschrieben in dem Schritt Anlegen eines Tokens). Ist das Token zur Absicherung schon generiert, ist es nicht notwendig, die Zahlungsdetails zu übertragen. Stattdessen muss das Token im Parameter transaction.payment_data.token übergeben werden, um die Zahlung abzuschließen.
