Checkout

Invoking Checkout causes consumers to enter the Paze^SM user interface (UI) via popup.

The SDK will render the following screens:
- Consumer authentication
- Card selection
- Shipping address selection or entry (if configured in the Checkout request)
The response of Checkout will contain masked card, consumer, and billing & shipping address, per the corresponding Checkout API request.
