    <script>
      
	    async function buildCheckout() {
	    
		    const yuno = Yuno.initialize(public_key);
	    
        yuno.startCheckout({
          checkoutSession: checkoutSessionId,
          elementSelector: "#root",
          countryCode: "BR",
          language: "pt",
          showLoading: true,
          keepLoader: true,
          issuersFormEnable: true,
          renderMode: {
            type: "element",
            elementSelector: "#rootElement",
          },
          card: {
            type: "extends",
            cardSaveEnable: true,
          },
       
          onLoading: (args) => {
            console.log(args);
          },
       
          async yunoCreatePayment(oneTimeToken) {
	          console.log("oneTimeToken: " + oneTimeToken)
	          
            **await createPayment();**          
            
            yuno.continuePayment({ showPaymentStatus: true });
          },
          yunoPaymentMethodSelected(data) {
            console.log("onPaymentMethodSelected", data);
          },
          yunoPaymentResult(data) {
            console.log("yunoPaymentResult", data);
            yuno.hideLoader();
          },
          yunoError: (error) => {
            console.log("There was an error", error);
            yuno.hideLoader();
          },
        });

        yuno.mountCheckoutLite({
          paymentMethodType: "{{type}}",
        });
      }
    </script>
  </body>
</html>

```

**Parâmetros**:

* **public\_key:** envie a sua chave pública cadastrada na Yuno;
* **checkoutSessionId**: você deverá enviar o `checkoutSession` que foi retornado na etapa “ [Criar Sessão de Pagamento](/api-reference/wallet-google-pay-e-apple-pay/criar-sessao-de-pagamento.md)”;
* **paymentMethodType:** você passará o `type` retornado na "[Listar Métodos de Pagamento](/api-reference/wallet-google-pay-e-apple-pay/listar-metodos-de-pagamento.md)".
  * ⚠️Possíveis `types`: **GOOGLE\_PAY**, **APPLE\_PAY**

🚨**Nota:** A função **`createPayment()`** deve ser substituída pelo endpoint a seguir:

## **Criar Pedido**

    "title": "Titulo - Lili UfdeDn",
    "payment": {

        }
    ],
    "uuidBuyer": "{{uuidBuyer}}"
}'
 
```

Quando a requisição for processada com sucesso você terá o seguinte retorno:
