Payment flow

The flow for the Merchant Acquirer API is as follows: 

  1. Submit a zero-value PaymentRequest to the /authorise endpoint, with the card alias as card number. For more information, see Submit a zero-value auth payment request.
  2. Adyen replace the alias in the PaymentResult with the card number, and submit the PaymentRequest to the merchant acquirer URL. For more information, see Merchant Acquirer request and response.
  3. The merchant acquirer replies to Adyen with a PaymentResult. For more information, see Merchant Acquirer request and response.
  4. Adyen forwards the received PaymentResult to you. The status received in the Merchant Acquirer Response will be the status of the Payment.
