Universal Checkout


The first fully dynamic checkout

Universal Checkout is a drop-in UI for web and mobile, with a no-code interface for product and payments teams. Now payments can be a first-class product area in your organization.

🛒

Accessible and responsive UX that presents the payment methods you choose, along with 3D Secure 2.0 and convenient checkout modules, fully in-context with no redirects, ever!

🎛️

Use the Dashboard to activate a custom set of payment methods and checkout modules based on amount, currency, customer location and more.

🎨

Completely customizable, embedded UI for seamless user experience on your site or in your app

🔐

PCI Level 1 compliant with a centralized vault for recurring payments and one-click checkout

🎉

Low code integration that you won't have to touch when adding new payment methods, processors or other Connections

🚀

Fully dynamic checkout driven by Workflows that let you fully automate end-to-end payment flows for the first time

Payment method tokenization

Universal Checkout securely captures payment method data while fully embedded on your site or in your app. By communicating directly with Primer's PCI-L1 tokenization service, Universal Checkout transforms sensitive customer data into a secure uniform string called a payment method token.

You can safely pass this token to your backend to create payments with the Payments API, with no compliance risk.

🚀

Our agnostic tokenization service and centralized vault enable you to handle recurring payments, fallbacks and retries across processors without compromising UX. No more PSP-specific tokens — now you own your payments data.


So, how does it work?

flow

Whether you're embedding in a website or a mobile app:

  1. 1
    Generate a clientToken on your backend by creating a Client Session.
  2. 2
    Initialize Universal Checkout with the clientToken to render the UI.
  3. 3
    As the user interacts with the checkout, Universal Checkout will propose to update the Client Session using Client Session actions.
  4. 4
    Universal Checkout will generate a paymentMethodToken when the customer submits their payment data.
  5. 5
    Create a payment using the paymentMethodToken via the Payments API.
  6. 6
    If the response indicates a requiredAction , you'll get a new clientToken.
  7. 7
    Pass the clientToken back to Universal Checkout to render next steps, like 3DS, and get a resumeToken.
  8. 8
    Call POST/payments/{id}/resume with the resumeToken to wrap things up. (If a new requiredAction is returned, you'll have to go back to step 5.)
🚨

Universal Checkout can dynamically handle front-end payment flows constructed in Worklows such as 3D Secure, KYC and more, enabling your payments team to craft new commerce experiences with no additional code.


Manage your checkout with no code

The Dashboard features a no-code interface enabling you to simply drag-and-drop payment methods and checkout modules and create conditions that determine when and how they are displayed on Universal Checkout.

Generate a client token to initialize the SDK

The clientToken is a temporary key used to initialize Universal Checkout, and render the checkout options you've configured with the Dashboard.

Generate the first client token by creating a Client Session.

If a payment method or checkout module requires additional information passed in the Client Session this will be documented in the Connection setup in the Dashboard.

🚨

Data you pass when requesting a clientToken is persisted in the payment request unless explicitly overwritten.
