# MoMo Android Component

Add MoMo to your Components integration.

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

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.

The additions you must make depends on the [server-side flow](https://docs.adyen.com/online-payments/build-your-integration) that your integration uses:

## Sessions flow Component

## Requirements

| Requirement           | Description                                                                                                                                                                                                                                       |   |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type**  | Make sure that you have an existing Sessions flow [Android Components integration](https://docs.adyen.com/online-payments/build-your-integration/sessions-flow?platform=Android).                                                                  |   |
| **Checkout API**      | Make sure that you use Checkout API v68 or later.                                                                                                                                                                                                 |   |
| **Redirect handling** | Make sure that your existing integration is set up to [handle the redirect](https://docs.adyen.com/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Components#handle-the-redirect). `action.type`: **redirect** |   |
| **Setup steps**       | Before you begin, [add MoMo in your Customer Area](https://docs.adyen.com/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](https://docs.adyen.com/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Components#create-a-payment-session).

### Import-Component

## Import the Component for MoMo

To [import the library](https://docs.adyen.com/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Components#import) and include the module for MoMo.

### Tab: With Jetpack Compose

**Import the module with Compose**

```java
implementation "com.adyen.checkout:instant:YOUR_VERSION"
implementation "com.adyen.checkout:components-compose:YOUR_VERSION"
```

### Tab: Without Jetpack Compose

**Import the module without Compose**

```java
implementation "com.adyen.checkout:instant:YOUR_VERSION"
```

### Add-Configuration

## Add additional configuration for MoMo

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

### Launch-And-Show

## Launch and show the Component for MoMo

To [create the Component](https://docs.adyen.com/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Components#launch-and-show) for MoMo, use the `InstantPaymentComponent` class.

### Tab: With Jetpack Compose

**Launch and show the Component**

```kotlin
import com.adyen.checkout.components.compose.get

// Get the payment method.
val paymentMethod = checkoutSession.getPaymentMethod("momo_wallet")

@Composable
private fun ComposableInstantPaymentComponent() {
  // Keep a reference to this Component in case you need to access it later.
  val instantComponent = InstantPaymentComponent.PROVIDER.get(
      checkoutSession = checkoutSession,
      paymentMethod = paymentMethod,
      configuration = checkoutConfiguration, 
      componentCallback = callback,
      // This key is required to ensure a new Component gets created for each different screen or payment session.
      // Generate a new value for this key every time you need to reset the Component.
      key = "YOUR_UNIQUE_KEY_FOR_THIS_COMPONENT",
  )

  // This is your composable, a wrapper around our xml view.
  AdyenComponent(
     component = instantComponent,
     modifier = YOUR_MODIFIER,
  )
}
```

### Tab: Without Jetpack Compose

```kotlin
// Get the payment method.
val paymentMethod = checkoutSession.getPaymentMethod("momo_wallet")

val instantComponent = InstantPaymentComponent.PROVIDER.get(
    activity, // Your activity or fragment.
    checkoutSession,
    paymentMethod,
    checkoutConfiguration, 
    componentCallback
)

// Attach the Component to your view.
binding.instantView.attach(instantComponent, activity) // Your activity or fragment.
```

### Recurring

## Recurring payments

MoMo supports recurring transactions. To make recurring transactions, you need to:

1. [Create a shopper token](https://docs.adyen.com/payment-methods/momo-wallet/android-component#create-a-token).
2. [Use the token to make future payments for the shopper](https://docs.adyen.com/payment-methods/momo-wallet/android-component#make-payment-with-token).

### Create a token

To create a token, include in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `storePaymentMethod`: **true**
* [shopperReference](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#request-shopperReference): Your unique identifier for the shopper.

When the payment has been settled, you receive a [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) [webhook](https://docs.adyen.com/development-resources/webhooks) containing:

* `type`: **recurring.token.created**
* `shopperReference`: your unique identifier for the shopper.
* `eventId`: the `pspReference` of the initial payment.
* `storedPaymentMethodId`: the token that you need to make recurring payments for this shopper.

Make sure that your server is able to receive the [Recurring tokens life cycle events](https://docs.adyen.com/development-resources/webhooks/webhook-types/#other-webhooks) webhook. You can [set up this webhook in your Customer Area](https://docs.adyen.com/development-resources/webhooks/#set-up-webhooks-in-your-customer-area).

### Make a payment with a token

To make a payment with the token, include in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `paymentMethod.storedPaymentMethodId`: The `storedPaymentMethodId` from the [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) webhook.

  You can also get this value using the [/listRecurringDetails](https://docs.adyen.com/api-explorer/Recurring/latest/post/listRecurringDetails) endpoint.

* `shopperReference`: the unique shopper identifier that you specified when creating the token.

* `shopperInteraction`: **ContAuth**

* `recurringProcessingModel`: Use **Subscription** for a series of transactions following a fixed time interval or **UnscheduledCardOnFile** for contracts with non-fixed time interval.

## Test and go live

To make MoMo payments in the test environment:

1. Download the MoMo test app for iOS or Android at <https://test-payment.momo.vn/download/>. If you are testing on a mobile browser, you see a link to download the test app. If you are testing on a desktop browser, use the test app to scan the QR code.
2. Use [MoMo's test credentials](https://developers.momo.vn/v3/docs/payment/onboarding/test-instructions) to log in to the test app. MoMo provides different credentials depending on the scenario that you want to test (for example, failed scenarios).

Check the status of MoMo test payments in your [Customer Area](https://ca-test.adyen.com/) > **Payments** > **Payment list**.

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

### Add Configuration

## Add additional configuration for MoMo

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

### Launch And Show

## Launch and show the Component for MoMo

To [create the Component](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Android\&integration=Components#launch-and-show) for MoMo, use the `InstantPaymentComponent` class.

### Tab: With Jetpack Compose

**Launch and show the Component**

```kotlin
import com.adyen.checkout.components.compose.get

// Create the payment method object from the /paymentMethods response.
val paymentMethod = paymentMethodsApiResponse?.paymentMethods.orEmpty().firstOrNull {
  it.type == "momo_wallet"
}

@Composable
private fun ComposableInstantPaymentComponent() {
    // Keep a reference to this Component in case you need to access it later.
    val instantComponent = InstantPaymentComponent.PROVIDER.get(
        paymentMethod = paymentMethod,
        configuration = checkoutConfiguration,
        componentCallback = callback,
        // This key is required to ensure a new Component gets created for each different screen or payment session.
        // Generate a new value for this key every time you need to reset the Component.
        key = "UNIQUE_KEY_PER_COMPONENT",
    )

    // This is your composable, a wrapper around our xml view.
    AdyenComponent(
        component = instantComponent,
        modifier = YOUR_MODIFIER,
    )
}

    activity, // Your activity or fragment.
    paymentMethod,
    checkoutConfiguration,
    componentCallback,
)

//Attach the Component to your view.
binding.instantView.attach(instantComponent, activity) // Your activity or fragment.
```

### Add Parameters Payments Request

## Add additional parameters to your /payments request

You do not need to add any parameters to the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request when you [make a payment](https://docs.adyen.com/online-payments/build-your-integration/advanced-flow/?platform=Android\&integration=Components#make-a-payment).

### Recurring

## Recurring payments

MoMo supports recurring transactions. To make recurring transactions, you need to:

1. [Create a shopper token](https://docs.adyen.com/payment-methods/momo-wallet/android-component#create-a-token).
2. [Use the token to make future payments for the shopper](https://docs.adyen.com/payment-methods/momo-wallet/android-component#make-payment-with-token).

### Create a token

To create a token, include in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `storePaymentMethod`: **true**
* [shopperReference](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#request-shopperReference): Your unique identifier for the shopper.

When the payment has been settled, you receive a [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) [webhook](https://docs.adyen.com/development-resources/webhooks) containing:

* `type`: **recurring.token.created**
* `shopperReference`: your unique identifier for the shopper.
* `eventId`: the `pspReference` of the initial payment.
* `storedPaymentMethodId`: the token that you need to make recurring payments for this shopper.

Make sure that your server is able to receive the [Recurring tokens life cycle events](https://docs.adyen.com/development-resources/webhooks/webhook-types/#other-webhooks) webhook. You can [set up this webhook in your Customer Area](https://docs.adyen.com/development-resources/webhooks/#set-up-webhooks-in-your-customer-area).

### Make a payment with a token

To make a payment with the token, include in your [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request:

* `paymentMethod.storedPaymentMethodId`: The `storedPaymentMethodId` from the [recurring.token.created](https://docs.adyen.com/api-explorer/Tokenization-webhooks/latest/post/recurring.token.created) webhook.

  You can also get this value using the [/listRecurringDetails](https://docs.adyen.com/api-explorer/Recurring/latest/post/listRecurringDetails) endpoint.

* `shopperReference`: the unique shopper identifier that you specified when creating the token.

* `shopperInteraction`: **ContAuth**

* `recurringProcessingModel`: Use **Subscription** for a series of transactions following a fixed time interval or **UnscheduledCardOnFile** for contracts with non-fixed time interval.

1. Download the MoMo test app for iOS or Android at <https://test-payment.momo.vn/download/>. If you are testing on a mobile browser, you see a link to download the test app. If you are testing on a desktop browser, use the test app to scan the QR code.
2. Use [MoMo's test credentials](https://developers.momo.vn/v3/docs/payment/onboarding/test-instructions) to log in to the test app. MoMo provides different credentials depending on the scenario that you want to test (for example, failed scenarios).

Check the status of MoMo test payments in your [Customer Area](https://ca-test.adyen.com/) > **Payments** > **Payment list**.

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