Introduction

With Payment Service Directive 2 (PSD2) it's required that all credit card payments have to be authenticated by the customer using strong customer authentication (SCA). See 3-D Secure.

Of course, this is only possible if the end customer is also present at the time of payment and can carry out an SCA (like 3-D Secure 1.0 or 3-D Secure 2.x).

This is precisely not the case with subscription models and micropayments (virtual account / billing), since these are carried out in the absence of the customer. For this purpose, the model "cards on file" or "credentials on file" (CoF in short) is offered, with which such payments are specially marked and then excluded from the SCA. Likewise, the first, initial payment must be authenticated using SCA to meet the PSD2 guidelines. Subsequent payment transactions can be initiated with reference to the initial payment transaction. The reference to the initial transaction will then be handled by the PAYONE platform.

CoF can also be used to speed checkout by first depositing a credit card for a customer and then referencing it for follow-up payments. This function has already been offered for a long time by the pseudo card number of the PAYONE Platform - but now CoF also makes it PSD2-compliant.

With CoF you may re-use a credit card number for recurring transactions where the customer can not proceed to the SCA process. To do so the initial payment process has to be authenticated via SCA and the customer has to be informed that their credit card number will be stored for subsequent payments, the purpose of payment and the amount that is expected. the CoF consent token will be stored referencing to the combination of merchantid (MID) and creditcardnumber (PPAN).

All online merchants who initiate recurring transactions in the form of CoF payments and have their customers' card data stored by themselves or their PSP storing the data must obtain the explicit consent of the cardholder / customer. This approval must include the following elements:

  •  The confirmation of the stored card number (PCI compliant, e.g., as a masked card number indicating the last four digits of the card number)
  •  The purpose for which the card data is used and the duration of the agreement
  •  Confirmation from the merchant that the cardholder will be notified of any changes in an agreed way

CoF and PAYONE Platform

With the support for CoF Payments we want to make the transition for our merchants as smooth as possible. To do this, we need to take care of the many different implementation ways our merchants are using today. We decided to deliver the CoF integration in different steps.

The first steps will be based on the already known parameters recurrence und customer_is_present. With this parameters, the merchant is able to set the use-case that needs to be processed.

After this step, we take care of our current integrations. We want to make sure that integrations based on ecommercemode=internet will still work in the beginning of 2021. With this step the merchants are able to plan the implementation of recurrence and customer_is_present while still being able to process with ecommercemode=internet.

For every transaction with ecommercemode=internet, we will internally set recurrence=recurring and customer_is_present=no, to flag that transaction as a subsequent recurring transaction.

The last step will be a more detailed way of integrating the CoF use cases. That will give our merchants every possible way of setting up exact recurring cycles and define for themselves, if a transaction is an initial transaction or not. We will deliver new parameters, that the merchant can use for a more detailed definition of CoF use cases. For this last step we already made some preparations in our api and you can take a closer look on the parameters, but the functionality in the PAYONE Platform is not finished yet.

So if you want to update your integration right now, you're fine with using the parameters recurrence and customer_is_present. An updated documentation with more details to the upcoming extensions will be coming soon.

While the solution for our merchants with ecommercemode=internet is based on our internal interpretation of recurrence and customer_is_present, this documentation will describe the definition of the use cases and how to set the 2 parameters.

Using recurrence and customer_is_present for CoF use cases

The PAYONE Platform already supports parameters for:

These parameters will be used for credit card payments to indicate CoF payments.

Here's an overview of different use cases with credit card payments and recurring transactions.

Initial transaction, followed by recurring payment

Description: The customer wants to save their credit card for future payments. the first initial transaction will be handled with 3-D Secure. The following transactions will be without 3-D Secure.

Subscription / contract / abo (recurring) - PAYONE contract module

Description: This use case applies if you want to use our Contract module to handle subscriptions where the amount for a trail period and subsequential periods are fixed and known when starting the contract.

Step Use case Server-API request Mandatory Parameters Comments
1

Initial create access - customer is present

createaccess
  • customer_is_present=yes
  • Success-URL
  • Back-URL
  • Error-URL
  • Merchant must obtain consent that data will be stored and be used for subsequent payments
  • Customer has to agree to CoF
  • Initial payment will be handled with 3-D secure
Important Note:

If Success-, Error and Back-URL are not provided or empty in the createaccess request, 3-D Secure will not be triggered and issuers will most likely respond with a soft-decline (error -120).

In the future, createaccess requests without those parameters or empty values will be declined over the Server- and Client-API.

handled automatically
  • Subsequent payments will be handled with CoF if customer agreed to the initial create access
