PayPal Integration

PayPal Logo

This guide walks you through integrating the DNA Payments PayPal Component (a PayPal Smart Payment Button rendered by our SDK) into your web application.

The PayPal merchant account, gateway configuration, and the server-side communication with the PayPal backend are handled by DNA Payments. You only need a terminal with PayPal enabled and a public HTTPS-hosted page.
