Diese Dokumentation soll verschiedenen POS-Partnern die Spezifikationen der Computop Paygate POS API zur Verfügung stellen, damit sie POS-Zahlungen über verschiedene Acquirer-Anbindungen integrieren und verarbeiten können.

WICHTIG: Je nach gewünschter Anbindungsart (z. B. P2PE, VNP oder SSL) sind bestimmte Parameter obligatorisch und umgekehrt. Dies gilt auch für die Implementierung bestimmter Zahlungsmethoden wie SEPA ELV, CLV+, Girocard oder MTT ATB, für die zusätzliche Daten aus der Standardanfrage benötigt werden.

Für detailliertere Empfehlungen zu den Datenanforderungen für bestimmte Produkte oder Integrationsarten wenden Sie sich bitte an das Computop-Team.

Antwort-Tags bei SEPA-ELV

Bei SEPA-ELV kann die Antwort optional folgende Tags enthalten:

5F53 (IBAN)
DF65 (Gläubiger-ID)

Hinweis: Sofern diese Felder vorhanden sind, müssen sie auch auf dem Dokument ausgedruckt werden.
5F53 (IBAN)
Länge: 34 Byte, Format: on
Die IBAN kann optional im BMP55 der Antwortnachricht (210,1410) enthalten sein. Sie ist maximal 34 Ziffern lang und darf keine Sonderzeichen und Kleinbuchstaben enthalten. In Deutschland wird eine 22-stellige IBAN verwendet.
Ist die IBAN im BMP55 enthalten, wird sie vollständig ausgedruckt oder vom Terminal aus dem BMP55, der auf dem Händler- und Kundenbeleg unter den Kartendaten erfasst wurde, mithilfe der Maskierungsregel (Tag DF25) maskiert.
Beispiel für eine Maskierung:
IBAN DE8553-0002
5F53 16 44 45 35 35 33 32 39 32 33 34 30 32 34 30 30 30 30 30 32
"DE85532912340123600002"
DF65 (Gläubiger-ID)
Länge: 8 - 35 Byte, Format: ans
Bei Online-Transaktionen kann der Bedienercomputer optional eine Gläubiger-ID in die Antwortnachricht (BMP55, Tag DF65-) einfügen. Wenn die BMP55 der Antwortnachricht eine Gläubiger-ID (DF65) enthält, wird diese im Händlerdokument oder anstelle des konfigurierten Kundendokuments (mit dem Konkretisierungszeichen „Gl“) ausgedruckt.
Beispiel:
DF65 12 444539385A5A5A3039393939393939393939393939393939393939

Bildung des DUKPTMAC

Zur Nachrichtenauthentifizierung fügt der Absender der Nachricht einen MAC (Message Authentication Code) hinzu, der vom Empfänger verifiziert wird.

Der Eingabeblock zur Berechnung des MAC ist wie folgt aufgebaut: Berechnung eines SHA-256-Codes über die Nachricht; einschließlich des Felds MessageType, des Felds MerchantID bis zum Feld DUKPTMAC (DMAC ausgeschlossen).
Das Ergebnis ist ein 32 Byte großer Eingabeblock, der zur Berechnung des MAC verwendet wird.

Der MAC wird mithilfe eines Arbeitsschlüssels generiert, der aus dem 3-DES-DUKPT-Sicherheitsschema abgeleitet wurde. Das Ergebnis der MAC-Berechnung ist ein 8-Byte-Nachrichtenauthentifizierungsblock (MAB), bestehend aus einem MAC (höchste 4 Byte) und einem verbleibenden MAC (niedrigste 4 Byte). Das MAC-Feld der Nachricht wird auf den MAB gesetzt. Die MAC-Generierung und -Verifizierung erfolgt gemäß ANSI X9.19.
