// Adyen Node API Library v30.0.1
import { Client, CheckoutAPI, Types } from "@adyen/api-library";

// For the LIVE environment, also include your liveEndpointUrlPrefix.
const config = new Config({
  apiKey: "ADYEN_API_KEY",
  environment: EnvironmentEnum.TEST
});

const client = new Client(config);

// Create the request object(s)
const amount: Types.checkout.Amount = {
  currency: "EUR",
  value: 1000
};

const paymentRequest: Types.checkout.PaymentRequest = {
  reference: "YOUR_ORDER_NUMBER",
  amount: amount,
  merchantAccount: "ADYEN_MERCHANT_ACCOUNT",
  shopperEmail: "s.hopper@@example.com",
  returnUrl: "https://your-company.com/checkout?shopperOrder=12xy.."
};

// Send the request
const checkoutAPI = new CheckoutAPI(client);
const response = checkoutAPI.PaymentsApi.payments(paymentRequest, { idempotencyKey: "UUID" });
```

The response includes `action.type`: **redirect**.

**Example response with a redirect action**

```json
{
    "resultCode":"RedirectShopper",
    "action":{
        "paymentMethodType":"ebanking_FI",
        "method":"GET",
        "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
        "type":"redirect"
    }
}
```
