## Get started with Instant Bank Transfer 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 Instant Bank Transfer.

3. **Configure a Workflow**\

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

### Prepare the client session

Instant Bank Transfer 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. `USD`. |
| 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_INSTANT_BANK_TRANSFER` 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 Instant Bank Transfer 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 Instant Bank Transfer 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 Instant Bank Transfer 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

Instant Bank Transfer 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 Instant Bank Transfer 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_INSTANT_BANK_TRANSFER` 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)**

Instant Bank Transfer 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**

Instant Bank Transfer 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_INSTANT_BANK_TRANSFER` wherever the code below references `YOUR_PAYMENT_METHOD_TYPE`.

**Universal Checkout (drop-in)**

Instant Bank Transfer 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**

Instant Bank Transfer 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).
