What is the Nayax Spark API?

Spark (formerly Cortina Remote Start) is a server-to-server payment microservice designed for EV charging networks, unattended retail, and any deployment where a third-party backend system needs direct control over the payment flow.

Unlike a standard terminal where the user interacts directly with the physical device, Spark gives your CSMS programmatic control over the payment flow. The Nayax device functions purely as a secure payment processor. Your CSMS retains full ownership of the user experience, business logic, loyalty programs, and dynamic pricing Nayax handles only the compliant payment processing and settlement.
