## Payment methods  <a href="#payment-methods__00a0" id="payment-methods__00a0"></a>

This screen allows the customers to select their preferred payment method. The payment method selection UI component can be customized to display only the methods that your system and business support. This component is optional and you are free to create your own UI.&#x20;
