Introduction to
Unified Checkout

Unified Checkout
 provides a single interface with which you can accept numerous types of card, digital, and alternative payments.
Unified Checkout
 calls other follow-on services such as Payments,
Decision Manager
,
Payer Authentication
, and
Token Management Service
 (
TMS
).
Unified Checkout
 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
 can be embedded seamlessly into your existing webpage, simplifying payment acceptance.
When a customer selects a payment method from the button widget,
Unified Checkout
 handles all interactions with the payment method that was chosen.
Unified Checkout
 is also able to orchestrate requests for to follow-on services such as Payments,
Decision Manager
,
Payer Authentication
, and
TMS
 before it provides a response to your e-commerce system.
