Wix Halkbank POS Installation Steps

Halkbank POS installation on Wix can be completed quickly and securely when the correct steps are followed. The first step is to add the API information provided by Halkbank to the Velo backend. Next, the payment initiation endpoint, verification endpoint, and callback URLs are configured.

To ensure the correct operation of 3D Secure redirects, a verification flow is created that checks bank return parameters, hash verification, and transaction result codes. After the customer confirms the transaction on Halkbank's verification screen, the system processes this data and completes the order.

If the installation steps are followed correctly, the Wix store will accept both installment and single payment transactions without any problems, and the payment flow will be completely secure.
