# Multibanco Web Component

Add Multibanco to your Components integration.

[View source](/payment-methods/multibanco/web-component.md)

You can add Multibanco to your existing integration. The following instructions show only what you must add to your integration specifically for Multibanco.

If an instruction on this page corresponds with a step in the main integration guide, it includes a link to that corresponding step of the main integration guide.

What you must add to your integration depends on the [server-side flow](/online-payments/build-your-integration) that your integration uses:

## Sessions flow Component

| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type** | Make sure that you have an existing Sessions flow [Web Components integration](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Components). |   |
| **Checkout API**     | Make sure that you use Checkout API v68 or later.                                                                                                                           |   |
| **Setup steps**      | Before you begin, [add Multibanco in your Customer Area](/payment-methods/add-payment-methods).                                                                             |   |

### Add-Parameters-Sessions-Request

## Add additional parameters to your /sessions request

You do not need to add any parameters when you [create a payment session](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Components#create-a-payment-session).

### Import

## Import Multibanco

When you [import Adyen Web](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Components#get-adyen-web), include `Multibanco`.

**Import**

```javascript
import { AdyenCheckout, Multibanco } from '@adyen/adyen-web';
```

### Add-Configuration

## Add additional configuration for Multibanco

You do not need to add any configuration parameters for Multibanco.

### Initialize

## Initialize the Component for Multibanco

To [initialize](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Components#initialize-the-payment-session) Multibanco, use the `Multibanco` class.

**Initialize the Component**

```javascript
const multibancoComponent = new Multibanco(checkout,
    {
    // The configuration object for Multibanco that you created.
    // Mount the Component to a container.
    }).mount('#multibanco-container')
```

## Test and go live

Before you can test Multibanco payments, you need to [submit a request for Multibanco](/payment-methods/add-payment-methods) in your [test Customer Area](https://ca-test.adyen.com/).

In the test environment, you can simulate a Multibanco payment by promoting the pending payment to a sale.

1. Log in to your [test Customer Area](https://ca-test.adyen.com/).
2. Go to **Transactions** > **Offers**.
3. Select the **PSP reference** of the pending Multibanco payment.
4. Select **Promote offer to sale** button.

Multibanco payments that have been paid (including test offers that you manually promoted to sale) are under **Transactions** > **Payments**.

Test the reconciliation process by promoting test payments from offer to sale in your [test Customer Area](https://ca-test.adyen.com/).

Before you can accept live Multibanco payments, you need to [submit a request for Multibanco](/payment-methods/add-payment-methods) in your [live Customer Area](https://ca-live.adyen.com/).
