Integration

Initiating a SOFORT payment request

The merchant begins by sending a SOFORT payment request to the BPE transaction gateway. The gateway processes this request and returns a response to the merchant.

• Without customer redirect: If the request is sent to a gateway that does not handle customer redirection, the response includes a redirect URL. The customer must be redirected to this URL manually.
• With customer redirect: If the original request redirects the customer to the Buckaroo public gateway, the transaction gateway automatically redirects the customer to the SOFORT payment page.
• Payment execution: Upon reaching the payment page, the customer inputs their banking details. Once these details are entered and verified, the payment is executed immediately. The customer is then redirected back to the merchant's website along with the payment result. Additionally, the payment engine sends a transaction push with the payment status.
