Integration

Each credit card has its subscription, meaning there are multiple services supporting credit card payments, one for each type of credit card. However, since all these credit cards work similarly, they are described together here. When referring to generic credit card payment details, we will use "credit card". If something is specific to a single card, the card will be named specifically.

Using the credit card service, a customer can pay using a credit card. The customer is presented with a screen where the credit card information can be provided.

MPI-Enabled Credit Cards

A credit card can be MPI-enabled; in this case, the customer will be redirected to a URL where the 3D Secure info can be provided. After completing this, the payment will proceed. After finishing the payment, the customer will be redirected back to the merchant's website.

The merchant starts by sending the request for a credit card payment to a BPE transaction gateway. The gateway processes the request and sends a response to the merchant. The response will contain a redirect URL to which the customer must be redirected. Once the customer reaches this page, they can enter their credit card details. If the card is not secured with a 3D Secure code, the payment is processed immediately, and the customer will be redirected back to the merchant's website along with the result. If the card is secured with a 3D Secure code, the customer is redirected to the 3D Secure page for their specific credit card, which is an external website of the card issuer. After completing the process on this page, the customer returns to the BPE transaction gateway, and the Payment Engine will process the credit card payment. The customer is then redirected back to the merchant's website along with the payment result. Additionally, the Payment Engine can perform a Transaction Push, updating the status of the payment.
