# Nuvei - Wero

> Configure Wero via Nuvei as a payment method in Gr4vy.

Nuvei is a global payment provider that provides comprehensive payment processing solutions across multiple payment methods and regions.

Wero is a digital wallet payment method available in Belgium and Germany that allows customers to make instant payments using their Wero account. It provides a fast and secure checkout experience for online purchases.

## Setup

Please follow the [common Nuvei instructions](./nuvei) to get set up with Nuvei.

After setting up your Nuvei account, make sure Wero is enabled as a payment method on your account.

Nuvei requires the following fields to be collected during checkout for Wero transactions:

* First name and last name
* Billing country
* Email address

## Features

Nuvei Wero payments support the following features:

* **Refunds** - Refund transactions in full or in part
* **Transaction synchronization** - Keep payment statuses synchronized with Nuvei

## Supported countries

Nuvei supports transactions from buyers in `BE` and `DE`.

## Supported currencies

Nuvei supports processing payments in `EUR`.

## Limitations

The following features are not supported by this connector:

* **Delayed capture** - Authorization and capture must happen together
* **Partial capture** - Cannot capture a portion of the authorized amount
* **Void** - Cannot cancel transactions once initiated
* **Payment method tokenization** - Cannot store payment methods for recurring transactions
* **Zero auth** - Zero-dollar verification transactions are not supported
* **Settlement reporting** - Settlement reporting is not available

## Integration

For Wero, the default integration for Nuvei is through a redirect to a hosted payments page.

Start by creating a new transaction with the following required fields.

<CodeGroup>
  ```csharp C# theme={"system"}
  var transaction = await client.Transactions.CreateAsync(
    transactionCreate: new TransactionCreate()
    {
      Amount = 1299,
      Currency = "EUR",
      Country = "DE",
      PaymentMethod =
        TransactionCreatePaymentMethod.CreateCheckoutSessionWithUrlPaymentMethodCreate(
          new RedirectPaymentMethodCreate()
          {
            Method = "wero",
            RedirectUrl = "https://example.com/callback",
          }
        ),
    }
  );
  ```

  ```go Go theme={"system"}
  amount := int64(1299)
  currency := "EUR"
  country := "DE"
  method := "wero"
  redirectUrl := "https://example.com/callback"

  redirectPaymentMethodCreate := components.RedirectPaymentMethodCreate{
    Method: method,
    RedirectUrl: redirectUrl,
  }
  paymentMethod := components.CreateTransactionCreatePaymentMethodRedirectPaymentMethodCreate(redirectPaymentMethodCreate)

  transactionCreate := components.TransactionCreate{
    Amount:        amount,
    Currency:      currency,
    Country:       &country,
    PaymentMethod: &paymentMethod,
  }

  transaction, err := client.Transactions.Create(ctx, transactionCreate, nil, nil)
  ```

  ```java Java theme={"system"}
  CreateTransactionResponse transactionResponse = gr4vyClient.transactions().create()
    .transactionCreate(TransactionCreate.builder()
      .amount(1299L)
      .currency("EUR")
      .country("DE")
      .paymentMethod(TransactionCreatePaymentMethod.of(RedirectPaymentMethodCreate.builder()
        .method("wero")
        .redirectUrl("https://example.com/callback")
        .build()))
      .build())
    .call();

  Transaction transaction = transactionResponse.transaction().orElse(null);
  ```

  ```php PHP theme={"system"}
  $transactionCreate = new TransactionCreate(
    amount: 1299,
    currency: 'EUR',
    country: 'DE',
    paymentMethod: new RedirectPaymentMethodCreate(
      method: 'wero',
      redirectUrl: 'https://example.com/callback'
    )
  );
  $response = self::$sdk->transactions->create($transactionCreate);
  $transaction = $response->transaction;
  ```

  ```python Python theme={"system"}
  transaction: models.Transaction = client.transactions.create(
    amount=1299,
    currency="EUR",
    country="DE",
    payment_method={
      "method": "wero",
      "redirect_url": "https://example.com/callback",
    }
  )
  ```

  ```ts TypeScript theme={"system"}
  const transaction = await gr4vy.transactions.create({
    amount: 1299,
    currency: "EUR",
    country: "DE",
    paymentMethod: {
      method: "wero",
      redirectUrl: "https://example.com/callback"
    }
  })
  ```
</CodeGroup>

After the transaction is created, the API response includes `payment_method.approval_url` and the `buyer_approval_pending` status.

```json theme={"system"}
{
  "type": "transaction",
  "id": "ea1efdd0-20f9-44d9-9b0b-0a3d71e9b625",
  "payment_method": {
    "type": "payment-method",
    "approval_url": "https://cdn.sandbox.spider.gr4vy.app/connectors/nuvei/apm.html?token=..."
  },
  "method": "wero"
}
```

Redirect the buyer to the `approval_url` so they can complete authentication and approve the payment. After approval the buyer is redirected to the `redirect_url` you provided when creating the transaction. Do not rely solely on the redirect - either poll the transaction or (recommended) rely on webhooks to detect the final status (for example `capture_succeeded` or failure states).

## Testing

Testing Wero transactions in the Nuvei sandbox requires using the **Wero Simulator**.

1. **Initiate a Transaction:** Start a Wero payment in your checkout using the Nuvei sandbox credentials.
2. **Locate the Short Code:** On the Wero checkout page (or in the redirection), identify the **10-character Short Code** (for example, `536-6CRN-CBT`).
   * *Note:* You do not need to decode the full QR string; the simulator requires the short text code.
3. **Access the Simulator:** Open the [Wero Example Consumer PSP portal](https://example-consumer-psps.int.epi.engineering/) for the integration environment.
4. **Create a Test Consumer:**
   * In the simulator, go to **Quick Tools** > **Local Profiles**.
   * Create a new consumer or select an existing one.
   * Ensure the consumer has a linked **Account** (Payment Mean). If not, add one (select **SCT Inst** and any country/bank).
5. **Approve Payment:**
   * Click on the **Consents** tab for your consumer.
   * Click **Give Consent**.
   * Enter the **Short Code** you retrieved in Step 2.
   * Confirm the transaction.

Your Nuvei Wero transaction should now be approved and automatically complete.
