How can I receive confirmation of payment on my server and handle card authentication requests?

All your incoming and outgoing transactions will be displayed in the Transactions tab on the left pane of the Arc portal, complete with statuses and other important details.

You can integrate your billing or CRM system with NayaPay Arc using APIs as well. 

Card authentication requests are handled by your customer’s bank. When the customer submits card details on the Checkout page, the information is sent to the customer’s bank’s 3D Secure system for OTP or mobile app-based authentication. Upon success, the card and transaction details are sent to the card schemes such as Visa, MasterCard, PayPak, etc. The card schemes send this information to the customer’s bank for the authorization of card transactions. On successful authorization, the card transaction is processed.
