Payment Flows

Spark supports multiple payment flows to handle different use cases depending on how the payment process is initiated.

• Remote Start: The transaction is initiated by the integrator's server remotely, often triggered by a consumer action outside the physical payment device (e.g., plugging in an EV charger).
• Device Start: The transaction begins directly from the Nayax payment terminal, where the consumer interacts with the device to select a service point or product.

Each flow involves a specific sequence of API calls and device interactions tailored for either integrator-driven or device-driven control, and uses a standard set of Spark API methods, such as StartAuthentication, TriggerTransaction, and Settlement. But the timing and responsibility differ depending on the initiator and logic owner. To learn more about each one, see the following pages.
