Introduction to
Click to Pay

Click to Pay
powered by
Unified Checkout
provides an interface for easy acceptance of
Click to Pay
payments from Visa, Mastercard, and American Express cards.
Click to Pay
consists of a server-side component and a client-side JavaScript library.
The server-side component authenticates your merchant identity and instructs the system to act within your payment environment. The response contains limited-use public keys. The keys are used for end-to-end encryption and contain merchant-specific payment information that drives the interaction of the application. The client-side JavaScript library dynamically and securely places digital payment options into your e-commerce page.
The provided JavaScript library enables you to place a payment application within your e-commerce environment. This embedded component offers
Click to Pay
and card entry to your customers.
Whether a customer uses a stored
Click to Pay
card or enters their payment information manually,
Click to Pay
handles all user interactions and provides a response to your e-commerce system.
