Native API Integration

Introduction:

In this integration method, all front-end pages must be developed by the merchant, allowing users to complete payments entirely within the merchant’s interface.

Supports both onramp and offramp scenarios:

• For onramp, the ACH response provides a link that directly redirects to the payment gateway page.Currently, onramp only supports Credit Cards, Google Pay, and Apple Pay.
• For offramp, the ACH response provides the receiving wallet address of the order.
• Require PCI certificate(Payment Card Industry Data Security Standard, PCI DSS) to integrate.
