`Unified Checkout` Flow

To integrate Unified Checkout into your platform, you must follow several integration steps. This section gives a high-level overview of how to integrate and launch Unified Checkout on your webpage and process a transaction. You can find the detailed specifications of the APIs later in this document.

Information that is captured by Unified Checkout, including the billing and shipping address, can be retrieved using the Payment Details API.

The figure below shows the Unified Checkout payment flow using the Sessions API to generate the capture context:

For more information on the specific APIs referenced, see these topics:

Sessions API: This generates the capture context and determines what fields are displayed to the customer in the UI during checkout.

Payment Details API: This API can be used to retrieve personally identifiable information that is associated with a Unified Checkout transient token, such as the cardholder name and billing and shipping details, without retrieving payment credentials.

Enabling `Unified Checkout` in the `Smartpay Fuse Portal`

To begin using Unified Checkout, you must first ensure that your merchant ID (MID) is configured to use the service and that any payment methods you intend to use are properly set up.
