Getting Started
Checkout V1 requires a url to be generated using the checkout API and using it to start the intent provided by the SDK.
Checkout V2 requires setting options of type AfterpayCheckoutV2Options
and creating handler methods for user interactions.
Both V1 and V2 involves configuring the SDK with the response from the /configuration
API endpoint as well as selecting and implementing a checkout method (V1 or V2).
Checkout V3 does not require direct SDK interaction with /configuration
API endpoint.
