As explained in this guide, Commerce Cloud integrates with CyberSource for credit card processing and Chase Paymentech for credit card and gift card processing. The security key and account information required for this integration are encrypted using a symmetric 256-bit AES key. For more information on the secure handling of credit and debit card data, refer to Configure Payment Processing.

Oracle Commerce Cloud integrates with PayPal Express Checkout. Calls to PayPal are not encrypted for transmission, as the merchant ID and secret key are never exposed on the storefront. (All calls to PayPal are made over HTTPS and performed on the server side.) For more information, refer to Configure the PayPal integration.

Oracle Commerce Cloud integrates with PayU Latam Web Checkout. Calls to PayU are not encrypted for transmission, as the merchant ID and secret key are never exposed on the storefront.
