Ich konnte das Plugin problemlos installieren und die Anbindung von PostFinance Checkout an meinen Woo-Commerce Shop hat problemlos funktioniert. Verstehe die negativen Bewertungen überhaupt nicht, da die erwähnten Probleme scheinbar nichts mit dem Plugin zu tun haben. –> Läuft einwandfrei!

We have been using the plug-in for years for our WooCommerce shop demos, it always works perfectly and the plug-ins are free of charge at PostFinance.

Ich muss hier auch eine Warnung aussprechen. Nicht nur ist das Plugin immer stark veraltet und produziert gravierende Fehler, es beeinflusst auch andere Zahlungsarten auf die es garkeinen Zugriff haben sollte! Im Moment lässt es Paypal- und Vorkasse-Zahlungen fehlschlagen, obwohl diese nichts mit dem Postfinance-Plugin zu tun haben. Das ist höchst unprofessionelle Programmierung. Hier fehlen absolut grundlegende Überprüfungen (z.B. ist das überhaupt eine Zahlungsart, die mich etwas angeht).

Seit September 2024 hat das Plugin bei uns schwerwiegende Probleme. Keine Zahlungen kommen durch. Der Support ist leider nutzlos und verwies monatelang auf GitHub. Dort ist leider einsehbar, dass so gut wie keine Sicherheitsmassnahmen aktiv sind. Nun meint der Techniker der Post, dass bei ihnen “alles richtig” läuft und es wird verlangt, dass ALLE ANDEREN Plugins stören. Tests in einer Sandbox zeigen aber, dass die anderen Plugins nichts mit den Störungen zu tun haben. Die Kommunikation ist, obwohl freundlich, absolut lächerlich – die Probleme bestehen nach acht Monaten noch immer. Tragisch. Ein Stern ist noch übertrieben.

Leider treten mit dem Plugin von PostFinance immer wieder gravierende Probleme auf. Für einen Dienstleister dieses Formats ist es enttäuschend, dass man sich mit einer derart mangelhaften Programmierung und unzureichender Qualitätssicherung zufriedengibt. Das Plugin ist äußerst langsam, schlecht optimiert und verursacht regelmäßig Fehler. Seit dem letzten Update funktioniert es erneut nicht zuverlässig – in einem Fall war sogar ein manueller Eingriff in die Datenbank erforderlich, um die Fehlfunktionen zu beheben. Liebe Entwickler: Mit dieser Umsetzung ist weder Ihnen noch Ihren Kunden geholfen. Es besteht dringender Verbesserungsbedarf.
