| **What does it do?**                | Checkout renders all payment buttons in a checkout list. The list order is determined by the order they are passed in the Sessions API.                                           | The trigger method launches into the payment screen without the need to have a separate `Unified Checkout` hosted payment button.                                               | The components method enables the client to compartmentalize and embed the checkout UI without the need for a separate `Unified Checkout` hosted payment button.                                                |
