REST JSON APIs
Lightweight but feature-rich JSON-based APIs, implementing the RESTful standard, allow easier integration and a faster time-to-live for your business.
Sometimes a [payment page integration] (https://docs.ngenius-payments.com/v2.0/docs/hosted-payment-page) just isn't enough.
If you intend to use a Direct API integration model, make sure you consider PCI- DSS compliance to safely capture and transmit card details.
