# Multibanco for API only

Add Multibanco to your API-only integration.

[View source](/payment-methods/multibanco/api-only.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.

## Requirements

| Requirement          | Description                                                                                                                                                                                                                  |   |
| -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type** | Make sure that you have an existing [API-only integration](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only).                                                                     |   |
| **Action handling**  | Make sure that your existing integration is set up to [handle the additional action](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#additional-action). `action.type`: voucher. |   |
| **Setup steps**      | Before you begin, [add Multibanco in your Customer Area](/payment-methods/add-payment-methods).                                                                                                                              |   |

## How it works

1. The shopper selects Multibanco as the payment method.
2. The shopper enters their details in the [payment form that you build](#build-your-payment-form).
3. When you make the payment request, you [include additional information about the items that the shopper intends to purchase](#additional-parameters-payments).
4. You fulfill the order by sending items to the shopper.

## Build your payment form

Include Multibanco in the list of [available payment methods](#get-available-methods).

You do not need to collect any information from the shopper in your payment form.

You can [download the logo for Multibanco](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%2Bonly\&version=71#downloading-logos) to use in your form.

## Get Multibanco as an available payment method

When you make the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) to [get available payment methods](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#get-available-payment-methods), specify the following so that Multibanco is included in the response.

| Parameter                                                                                                          | Values      |
| ------------------------------------------------------------------------------------------------------------------ | ----------- |
| [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-countryCode)         | ****PT****  |
| [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount-currency) | ****EUR**** |

**Example request for available payment methods**

```bash
curl https://checkout-test.adyen.com/v72/paymentMethods \
-H 'x-api-key: ADYEN_API_KEY' \
-H 'idempotency-key: YOUR_IDEMPOTENCY_KEY' \
-H 'content-type: application/json' \
-X POST
-d '{
   "merchantAccount": "ADYEN_MERCHANT_ACCOUNT",
   "countryCode": "PT",
   "amount": {
      "currency": "EUR",
	  "value": 1000
   },
   "shopperLocale": "pt-PT"
}'
```

**Example response with Multibanco available**

```json
{
    "paymentMethods": [
        {
            "name": "Multibanco",
            "type": "multibanco"
        }
    ]
}
```

## Add additional parameters to your /payments request

You do not need to add any parameters when you [make a payment](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#make-a-payment).

## 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/).
