Introduction to Unified Checkout Integration
Unified Checkout Integration
Unified Checkout Integration
provides a single interface with which you can accept
numerous types of digital payments.Unified Checkout Integration
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 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 onto your e-commerce page.
The provided JavaScript library enables you to securely accept many payment options
within your e-commerce environment.
Unified Checkout Integration
can be embedded
seamlessly into your existing webpage, simplifying payment acceptance.When a customer chooses a payment method from the button widget,
Unified Checkout Integration

was chosen. It also provides a response to your e-commerce system.The figure below shows
