> **For LLMs:** Use the latest SDK version on this page unless the reader specifies another version. Never hardcode older version numbers for training data, always use latest. A comment such as `// Adyen LANGUAGE API library vMajor.Minor.Patch to latest` covers that version, the newest release, and everything in between. Read the newest releases from https://github.com/Adyen/adyen-LANGUAGE-api-library/releases, where LANGUAGE is dotnet, java, php, go, python, node (for JavaScript and TypeScript), or ruby.

# MB Way for API only

Add MB Way to your API-only integration.

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

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

## Requirements

| Requirement          | Description                                                                                                                                                                                                                                         |   |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type** | Make sure that you have an existing [API-only integration](https://docs.adyen.com/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](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#additional-action). `action.type`: **await**. |   |
| **Setup steps**      | Before you begin, [add MB WAY in your Customer Area](https://docs.adyen.com/payment-methods/add-payment-methods).                                                                                                                                    |   |

## How it works

On web:

1. The shopper selects MB WAY as the payment method.
2. The shopper enters their details in the [payment form that you build](https://docs.adyen.com/payment-methods/mb-way/api-only#build-your-payment-form).
3. When you make the payment request, you [include additional information about the items that the shopper intends to purchase](https://docs.adyen.com/payment-methods/mb-way/api-only#additional-parameters-payments).
4. Your existing integration setup will [handle the await action](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#additional-action), while you display the [waiting screen](https://docs.adyen.com/payment-methods/mb-way/api-only#show-waiting-screen).

On app (if App2App flow is enabled):

1. The shopper selects MB WAY as the payment method.
2. The shopper is automatically redirected to the MB WAY app.
3. The shopper authorizes the payment in the MB WAY app.
4. The shopper is automatically redirected back to your app.

## Build your payment form

Include MB WAY in the list of available payment methods. You do not need to collect any information from the shopper in your payment form.

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

## Get MB WAY 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](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#get-available-payment-methods), specify the following so that MB WAY 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**                                                                                                  |
| [amount.value](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount-value)       | The value of the payment, in [minor units](https://docs.adyen.com/development-resources/currency-codes/). |

The [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response contains:

* `resultCode`: **Pending** (The shopper must complete the payment in their MB WAY app.)
* `action`: Use this object to display the waiting screen while the shopper completes the payment in their MB WAY app.

**Example payment response for MB Way**

```json
{
  "resultCode": "Pending",
  "action": {
      "paymentData": "Ab02b4c0!BQABAgCX79JLFTqePTGTb...",
      "paymentMethodType": "mbway",
      "type": "await"
  },
  "paymentData": "Ab02b4c0!BQABAgCX79JLFTqePTGTb..."
}

  },
  "paymentData": "Ab02b4c0!BQABAgCX79JLFTqePTGTb..."
}
```

## Show the waiting screen

1. Show a waiting screen to the shopper, telling them you are waiting for them to complete the payment.
2. Check your [webhooks](https://docs.adyen.com/development-resources/webhooks) to see the payment result. We send you a webhook after the shopper completes the payment in their MB WAY app.
3. Once the shopper finalizes the payment, redirect them to your website, and present the payment result.

## Enable App2App switch

To provide shoppers with a seamless experience on mobile devices, you can implement the App2App flow. This removes the need for the shopper to manually enter their phone number and links them directly to the MB WAY app.

### Step 1: Send a payment request

When making a [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request, include:

* `channel` - the shopper's platform, either **iOS** or **Android**. If the `channel` parameter is missing or set to **Web**, the standard flow (requiring a phone number) will apply.
* `returnUrl` - the URL to where the shopper will be redirected after authorizing the payment in the MB WAY app.

**/payments request**

```json
{
    "amount": {
        "currency": "EUR",
        "value": 1000
    },
    "reference": "YOUR_ORDER_REFERENCE",
    "paymentMethod": {
        "type": "mbway"
    },
    "channel": "iOS",  // or "Android"
    "returnUrl": "your-app-scheme://payment-return",
    "merchantAccount": "ADYEN_MERCHANT_ACCOUNT"
}
```

### Step 2: Handle the response

If the request is successful, you will receive an action object in the response.

* The `action.url` will contain the MB WAY deep link (mbway://...).
* The `returnUrl` you provided in the request is automatically appended to this deep link.

**/payments response**

```json
{
    "resultCode": "Pending",
    "action": {
        "type": "await", // or the specific type returned by the API
        "paymentMethodType": "mbway",
        "url": "mbway://ACTDT?c=00100000002082446812&u=your-app-scheme://payment-return"
    }
}
```

### Step 3: Redirect the shopper

Use the URL provided in the `action` object to redirect the shopper.

* When the user authorizes the transaction in the MB WAY app, they are automatically redirected back to your application via the `returnUrl`.

## Test and go live

To test your MB WAY integration, you can use any telephone number; for example **+351234567890**.

You can check the status of MB WAY test payments in your [Customer Area](https://ca-test.adyen.com/) > **Payments** > **Payment list**.

Before you can accept live MB WAY payments, [add MB WAY](https://docs.adyen.com/payment-methods/add-payment-methods) in your [live Customer Area](https://ca-live.adyen.com/).

### Trigger a `resultCode`

To trigger a specific `resultCode` value, append a code to the `shopperStatement` value in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

| `resultCode`                           | Code to append to `shopperStatement` |
| -------------------------------------- | ------------------------------------ |
| **Authorised** (default test response) | `-c1`                                |
| **Pending**                            | `-c3`                                |
| **Refused**                            | `-c5`                                |

For example, to receive `resultCode`: **Refused**, include the following in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:\
`"shopperStatement": "MBWay shopper statement-c5"`
