# Multibanco Web Drop-in

Add Multibanco to your Drop-in integration.

[View source](/payment-methods/multibanco/web-drop-in.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 Drop-in

### Drop-In-Before-You-Begin

## Requirements

| Requirement          | Description                                                                                                                                                           |   |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type** | Make sure that you have an existing Sessions flow [Web Drop-in integration](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Drop-in). |   |
| **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).                                                                       |   |

### Drop-In-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=Drop-in#create-a-payment-session).

### Drop-In-Import-Optional

## Import Multibanco (optional)

When you [import Adyen Web](/online-payments/build-your-integration/sessions-flow?platform=Web\&integration=Drop-in#get-adyen-web), you can optionally import individual payment methods to optimize performance by using [tree shaking](https://developer.mozilla.org/en-US/docs/Glossary/Tree_shaking). To do this, include `Multibanco`.

**Import**

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

### Drop-In-Test-And-Go-Live

## 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/).
