Overview

Cortina API allows third-party integrators, such as payment providers or Payment Gateways, to process payment transactions securely and efficiently. It acts as a communication layer that enables Nayax’s devices to interact with external payment platforms through well-defined request/response flows.

See the diagram below:

Where:

1. Customer: Customers initiate payment by presenting their payment method at the POS (Point of Sale) terminal.
2. POS (Point of Sale): The POS terminal receives the credit card details and the transaction amount. It then sends the card and transaction details to the Nayax server for further processing.
3. Nayax: Nayax receives the payment request and uses the Cortina API to verify the transaction. The API handles the transaction's authentication, authorization, and final settlement.
4. Payment Gateway: The Payment Gateway processes the transaction details, authorizes the payment, and clears funds.

Nayax uses the Cortina API to authorize and clear the transaction, ensuring that the payment is valid and processing it securely.
