# BIZUM via Nuvei

> Let customers pay using BIZUM via Nuvei in Spain.

BIZUM via Nuvei is a Spanish instant mobile payment method linked directly to bank accounts. The customer is redirected to their banking app to authorise the payment in real time. EUR only, targeted at Spanish consumers.

## Get started with BIZUM via Nuvei

### Before you begin

If this is your first payment method, follow the [Get started guide](https://primer.io/docs/get-started/overview.md) to begin processing payments with Primer.

### Configure in the Dashboard

1. **Add Nuvei to your Dashboard**\

   Go to [Integrations](https://dashboard.primer.io/integrations), click **New Integration**, and search for Nuvei. Enter your Nuvei credentials.

2. **Activate on the Checkout**\

   Go to [Checkout](https://dashboard.primer.io/checkout) and activate BIZUM.

3. **Configure a Workflow**\

   Ensure a Workflow with an **Authorization** action is set up to process APMs.

### Prepare the client session

BIZUM via Nuvei leverages the following parameters to process a payment. Pass them when creating the client session.

| Parameter Name | Required | Description |
| - | - | - |
| orderId | ✓ | A unique identifier for the order. Maximum 255 characters. |
| currencyCode | ✓ | 3-letter currency code in ISO 4217 format, e.g. `EUR`. |
| amount | ✓ | A positive integer representing the amount in the smallest currency unit. |

## Prepare the SDK for payments

**Web**

> [!NOTE]
>
> Use the payment method type `NUVEI_BIZUM` wherever the code below references `YOUR_PAYMENT_METHOD_TYPE`.

**Primer Checkout (recommended)**

Primer Checkout is our latest web SDK, built around declarative web components. Once BIZUM is enabled in your [Dashboard](https://dashboard.primer.io/checkout), the default `<primer-checkout>` layout renders it automatically alongside your other methods — no payment-method-specific markup is required.

```html theme={"dark"}
<primer-checkout client-token="your-client-token"></primer-checkout>
```

#### Custom layouts

Only reach for [primer-payment-method](https://primer.io/docs/sdk/primer-checkout-web/components/primer-payment-method.md) if you're building a custom layout and need to place BIZUM at a specific position. The element only renders when the type is enabled in your Dashboard and returned by the server for this checkout.

```html theme={"dark"}
<primer-checkout client-token="your-client-token">
  <primer-main slot="main">
    <div slot="payments">
      <primer-payment-method type="YOUR_PAYMENT_METHOD_TYPE"></primer-payment-method>
    </div>
  </primer-main>
</primer-checkout>
```

For dynamic rendering based on what the server returns, listen to [primer:methods-update](https://primer.io/docs/sdk/primer-checkout-web/events-reference.md) or use [primer-payment-method-container](https://primer.io/docs/sdk/primer-checkout-web/components/primer-payment-method-container.md) for declarative filtering.

**Universal Checkout (legacy)**

##### Set up redirects

If BIZUM can't be shown in a popup, Universal Checkout redirects the customer back to your site using the `returnUrl` passed in the `redirect` options. See [Handle redirects & deep links](https://primer.io/docs/sdk/web/v2.x.x/handle-redirects-and-deeplinks.md#set-up-redirects) for the full flow.

```typescript theme={"dark"}
const options = {
  container: "#checkout-container",
  redirect: {
    returnUrl: "https://mystore.com/checkout",
  },
  onCheckoutComplete({ payment }) {
    console.log("Checkout complete.", payment);
  },
};
```

##### Show Universal Checkout

BIZUM is automatically presented when calling [Primer.showUniversalCheckout](https://primer.io/docs/sdk/web/v2.x.x/primer/methods/showUniversalCheckout.md).

```typescript theme={"dark"}
import { Primer } from "@primer-io/checkout-web";

try {
  await Primer.showUniversalCheckout(clientToken, options);
} catch (e) {
  // handle error
}
```

Check the [customization guide](https://primer.io/docs/checkout/drop-in/customization.md#styling-payment-method-button) to learn how to customize payment method buttons.

**Headless Universal Checkout (legacy)**

Create a `RedirectPaymentMethodManager` for BIZUM using [createPaymentMethodManager](https://primer.io/docs/sdk/web/v2.x.x/primer-headless-checkout/methods/createPaymentMethodManager.md#redirect), then call `start()` to begin the redirect flow.

```typescript theme={"dark"}
const manager = await headless.createPaymentMethodManager("YOUR_PAYMENT_METHOD_TYPE");

if (manager) {
  manager.addEventListener("click", () => {
    // Optional: run custom logic before the redirect flow starts.
  });

  await manager.start();
}
```

Refer to the full guide for [handling payment methods with redirect](https://primer.io/docs/checkout/headless.md#step-4c-handle-payment-methods-with-redirect).

**iOS**

> [!NOTE]
>
> Use the payment method type `NUVEI_BIZUM` wherever the code below references `YOUR_PAYMENT_METHOD_TYPE`.

#### Set up redirects

Redirect-based payment methods present a webpage or open a third-party app for the customer to authorize the payment. To return to your app once the customer has authorized the payment, include the `urlScheme` parameter when configuring `PrimerPaymentMethodOptions`.

```swift theme={"dark"}
let settings = PrimerSettings(
  // ...
  paymentMethodOptions: PrimerPaymentMethodOptions(
    urlScheme: "your-url-scheme://" // e.g. primer://, yourscheme://
  )
  // ...
)
```

When the customer is redirected back to your app, iOS calls `application(_:continue:restorationHandler:)`. Forward the call to the Primer SDK so the checkout can continue the flow.

```swift theme={"dark"}
import PrimerSDK
import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
  // ...
  func application(
    _ application: UIApplication,
    continue userActivity: NSUserActivity,
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
  ) -> Bool {
    return Primer.shared.application(
      application,
      continue: userActivity,
      restorationHandler: restorationHandler
    )
  }
}
```

#### Show the payment method

**Universal Checkout (drop-in)**

BIZUM is automatically presented when calling [Primer.shared.showUniversalCheckout](https://primer.io/docs/sdk/ios/v2.x.x/primer/methods/showUniversalCheckout.md).

```swift theme={"dark"}
class MyViewController: UIViewController {
  func startUniversalCheckout() {
    Primer.shared.showUniversalCheckout(clientToken: self.clientToken)
  }
}
```

Check the [customization guide](https://primer.io/docs/checkout/drop-in/customization.md#styling-payment-method-button) to learn how to customize payment method buttons.

**Headless Universal Checkout**

BIZUM requires a [Native UI Manager](https://primer.io/docs/checkout/headless.md#native-ui-manager) to be presented to the customer.

```swift theme={"dark"}
// 👇 Create the payment method manager
let nativeUIPaymentMethodManager = try PrimerHeadlessUniversalCheckout.NativeUIManager(
  paymentMethodType: "YOUR_PAYMENT_METHOD_TYPE"
)

// 👇 Show the payment method
try nativeUIPaymentMethodManager.showPaymentMethod(intent: .checkout)
```

See [NativeUIManager.init](https://primer.io/docs/sdk/ios/v2.x.x/primer-headless-checkout/native-ui-manager/init.md) for the full API. As many redirect-based payment methods share this approach, we recommend centralizing the implementation — see the worked example in the [Native UI Manager guide](https://primer.io/docs/checkout/headless.md#native-ui-manager).

**Android**

> [!NOTE]
>
> Use the payment method type `NUVEI_BIZUM` wherever the code below references `YOUR_PAYMENT_METHOD_TYPE`.

**Universal Checkout (drop-in)**

BIZUM is automatically presented when calling [Primer.instance.showUniversalCheckout](https://primer.io/docs/sdk/android/v2.x.x/primer/methods/showUniversalCheckout.md).

```kotlin theme={"dark"}
class CheckoutActivity : AppCompatActivity() {
  private fun setupObservers() {
    viewModel.clientToken.observe(this) { clientToken ->
      showUniversalCheckout(clientToken)
    }
  }

  private fun showUniversalCheckout(clientToken: String) {
    Primer.instance.showUniversalCheckout(this, clientToken)
  }
}
```

Check the [customization guide](https://primer.io/docs/checkout/drop-in/customization.md#styling-payment-method-button) to learn how to customize payment method buttons.

**Headless Universal Checkout**

BIZUM requires a [Native UI Manager](https://primer.io/docs/checkout/headless.md#native-ui-manager) to be presented to the customer.

```kotlin theme={"dark"}
// 👇 Create the payment method manager
val nativeUiManager = PrimerHeadlessUniversalCheckoutNativeUiManager.newInstance("YOUR_PAYMENT_METHOD_TYPE")

// 👇 Show the payment method
nativeUiManager.showPaymentMethod(this, PrimerSessionIntent.CHECKOUT)
```

See [NativeUiManager.newInstance](https://primer.io/docs/sdk/android/v2.x.x/primer-headless-checkout/native-ui-manager/newInstance.md) for the full API. As many redirect-based payment methods share this approach, we recommend centralizing the implementation — see the worked example in the [Native UI Manager guide](https://primer.io/docs/checkout/headless.md#native-ui-manager).
