Info

The international online bank transfer with PIN/TAN from Sofort GmbH is now available in 13 countries. As part of the Klarna Group Sofort offers the integration of payment in the webshop, so that a customer is forwarded to his/her bank and can make the transfer with input of PIN and TAN.

TypePayments by Online Bank Transfer


Further information can be found on the webpage of Sofort (https://www.sofort.com/ger-DE/verkaeufer/su/e-payment-sofort-ueberweisung).

Sofort has several advantages: This method is a prepayment which minimizes the date of payment for the merchant. The customer is using the familiar and trustworthy online banking of its own financial institution, just the same as with online banking.

Computop Paygate supports Sofort of Sofort GmbH in many countries in Europe. Currently supported countries can be found on the webpage https://www.sofort.com/ger-DE/verkaeufer/su/e-payment-europaweit-mit-sofort-xxl/.

Sofort is a method of bank transfers and is based on online banking. A big advantage is: The customer doesn’t need to register and does not need to create a virtual account, a so called wallet. As the name suggests it is an immediate bank transfer and thus a direct bank transfer. The customer selects Sofort as payment method for their online purchase and is then forwarded to the secure payment form. The bank transfer data is transferred automatically and the customer only has to select his or her bank and enter their login details for online banking. Finally he releases the bank transfer by means of an approval code. All data is send encrypted to the online banking account. The online merchant receives a real-time confirmation of the executed bank transfer. The merchant can execute and dispatch the order immediately delivering goods/services faster. There is no waiting time until the dispatch of the goods like it would be for example in the case of prepayment via bank transfer.

In the Netherlands iDEAL is established as a method for direct bank transfers. The process is similar to other methods for direct bank transfers. Prerequisite for using iDEAL via Sofort is a business account with the Deutsche Handelsbank for receiving payments.

As usual with online banking, the data disclosed in Sofort are encrypted with SSL (Secure Sockets Layer).

Credit with Sofort

Credits (refunds) are possible via a Server-to-Server connection. Paygate permits credits which relate to a capture previously activated by Paygate and allows merchants to carry out credits without a reference transaction. In order to make a credit you need to have an account with the Deutsche Handelsbank.

The necessary API key for communication you will find in the menu of your Sofort account in the section Further services at API-Key:

To carry out a credit with a reference transaction, please use the following URL:


Notice: For security reasons, Computop Paygate rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter.

ReqId

ans..32

O

To avoid double payments / actions, enter an alphanumeric value which identifies your transaction and may be assigned only once. If the transaction / action is submitted again with the same ReqID, Computop Paygate will not carry out the payment or new action, but will just return the status of the original transaction / action. Please note that the Computop Paygate must have a finalized transaction status for the first initial action. Submissions with identical ReqID for an open status will be processed regularly.

Um Doppelzahlungen zu vermeiden, übergeben Sie einen alphanumerischen Wert, der Ihre Transaktion / Aktion identifiziert und nur einmal vergeben werden darf. Falls die Transaktion oder auch jede Aktion mit derselben ReqID erneut eingereicht wird, führt das Computop Paygate keine Zahlung / weitere Aktion aus sondern gibt nur den Status der ursprünglichen Transaktion / Aktion zurück. Bitte beachten Sie, dass das Computop Paygate für die erste initiale Aktion einen abgeschlossenen Transaktionsstatus haben muss. Einreichungen mit identischer ReqID auf einen offenen Status werden regulär verarbeitet.
