edX has made available the integration of Stripe for payments on its platform.
edX uses CyberSource and PayPal to accept payments, but the codebase now contains support for Stripe.
This development includes support for charges via credit card entry, Apple Pay, Pay with Google, and Payment Request API (which is a W3C browser standard that provides Apple Pay-like behavior across different browsers).
These payment methods use tokenization. Sensitive data–credit card number, card expiration date, and CVC is relayed to Stripe in exchange for a token. This token is sent to the e-commerce service in order to complete the checkout process.
