# Card Component v4.x.x integration

Add card payments to your existing Components integration.

[View source](/payment-methods/cards/android-component/earlier-versions.md)

This page explains how to add cards to your existing Android Components integration.

Our [Card Component](/online-payments/build-your-integration/sessions-flow?platform=Android\&integration=Components) renders the available cards in your payment form, and securely collects sensitive card information, so it doesn't touch your server.

## Requirements

| Requirement          | Description                                                                                                                                                                       |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Integration type** | Make sure that you have built an Advanced flow [Android Components integration](/online-payments/build-your-integration/advanced-flow/?platform=Android\&integration=Components). |
| **Setup steps**      | Before you begin:- [Aadd the cards that you want to accept in your Customer Area](/payment-methods/add-payment-methods).
- [Get your client key](#get-client-key).                |

### Get your client key

1. Log in to your [Customer Area](https://ca-test.adyen.com/).
2. Go to **Developers** > **API credentials**, and select the credential username for your integration, for example **ws\@Company.\[YourCompanyAccount]**.
3. Under **Client settings** > **Authentication** select the **Client key** tab.
4. Select **Generate client key**.
5. Select the copy icon **and store your client key securely in your system.
6. Under **Add allowed origins**, enter your [domains](/development-resources/client-side-authentication#allowed-origins) and select **Add**.
7. Select **Save changes**.

## Show the available cards in your payment form

For information about the supported locations and currencies for each card, refer to [Payment methods](https://www.adyen.com/payment-methods).

To show the Card Component in your payment form, you need to:

1. Specify in your [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) request a combination of [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) and [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount). This is used to determine which cards are available to the shopper.

2. Deserialize the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) response, and get the object with `type`: **scheme**.\
   For showing stored cards, get the object with `type`: **storedPaymentMethods**.

3. Add the Card Component:

   a. Import the Card Component to your `build.gradle` file.

   ```groovy
     implementation "com.adyen.checkout:card:<latest-version>"
   ```

   For the latest version, refer to our [GitHub](https://github.com/Adyen/adyen-android).

   b. []()Create a `cardConfiguration` object, and pass your client key. You can also include [optional configuration](#optional-configuration), for example to make the cardholder name required.

   ```kotlin
    val cardConfiguration = CardConfiguration.Builder(context, "YOUR_CLIENT_KEY")
         // Makes the cardholder name required
         .setHolderNameRequired(true)
         // When you are ready to accept live payments, change the value to one of our live environments.
         .setEnvironment(Environment.TEST)
         .build()
   ```

   c. []()Initialize the Card Component. Pass the object from the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) response and the `cardConfiguration` object.

   ```kotlin
      val cardComponent = CardComponent.PROVIDER.get(this@YourActivity, paymentMethod, cardConfiguration)
   ```

   d. Add the Card Component view to your layout.

   ```xml
      <com.adyen.checkout.Card.CardView
             android:id="@+id/cardView"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"/>
   ```

   e. Attach the Component to the view to start getting your shopper's payment details.

   ```kotlin
      cardView.attach(cardComponent, this@YourActivity)
   ```

   f. When shoppers enter their payment details, you start receiving updates. If `isValid` is true and the shopper proceeds to pay, pass the `paymentComponentState.data` to your server and [make a payment request](#make-a-payment).

   ```kotlin
    cardComponent.observe(this) { paymentComponentState ->
       if (paymentComponentState?.isValid == true) {
          // When the shopper proceeds to pay, pass the `paymentComponentState.data` to your server to send a /payments request
          sendPayment(paymentComponentState.data)
       }
    }
   ```

### Optional configuration

When you create the [`CardConfiguration` ](https://adyen.github.io/adyen-android/card/com.adyen.checkout.card/-card-configuration/index.html)object, you can optionally add configuration parameters.

#### Address field configuration

Configure the postal code field in `AddressConfiguration.PostalCode`.

Include the following parameter:

| Parameter            | Description                                                                                                                                                                                                                                             | Default value |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- |
| `addressFieldPolicy` | Set if shoppers are required to fill in the fields. Possible values: - **Required** - **Optional** - **OptionalForCardTypes**: include the `brand` parameter, which is a list of values of type `String` to specify which brands input is optional for. | **Required**  |

**Address field settings**

```kotlin
// Create a configuration object for the postal code field.
val addressConfiguration = AddressConfiguration.PostalCode(
    // Set it as optional for specific brands.
    addressFieldPolicy = AddressConfiguration.AddressFieldPolicy.OptionalForCardTypes(
       // Provide a list of strings to specify the brands.
       brands = listOf("jcb", "cup")))

// Set address configuration in card configuration object
val cardConfiguration = CardConfiguration.Builder(context, "YOUR_CLIENT_KEY")
    .setAddressConfiguration(addressConfiguration)
```

## Make a payment

When the shopper proceeds to pay, the Component returns the `paymentComponentState.data.paymentMethod`.

1. Pass the `paymentComponentState.data` to your server.

2. From your server, make a [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request, specifying:

   * `paymentMethod`: The `paymentComponentState.data.paymentMethod` from your client app.

}
```

## Present the payment result

Use the  [resultCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#responses-200-resultCode) from the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response to present the payment result to your shopper. You will also receive the outcome of the payment asynchronously in a [webhook](/development-resources/webhooks).

For card payments, you can receive the following `resultCode` values:

| resultCode     | Description                                                                                                                                               | Action to take                                                                                                                                                                                         |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Authorised** | The payment was successful.                                                                                                                               | Inform the shopper that the payment has been successful. If you are using [manual capture](/online-payments/capture#manual-capture), you also need to [capture](/online-payments/capture) the payment. |
| **Cancelled**  | The shopper cancelled the payment.                                                                                                                        | Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.                                                                                        |
| **Error**      | There was an error when the payment was being processed. For more information, check the [`refusalReason` ](/development-resources/refusal-reasons)field. | Inform the shopper that there was an error processing their payment.                                                                                                                                   |
| **Refused**    | The payment was refused. For more information, check the [`refusalReason` ](/development-resources/refusal-reasons)field.                                 | Ask the shopper to try the payment again using a different payment method.                                                                                                                             |

Additional `resultCode` values are possible in case of the 3D Secure authentication flow. For more information, refer to [Result codes](/online-payments/build-your-integration/payment-result-codes/#3d-secure-authentication).

## Recurring payments

Adyen's [tokenization service](/online-payments/tokenization) allows you to securely store shopper's card details for recurring payments. To make recurring payments, you first need to create a shopper token, and then use the token to make future payments for the shopper.

### Create a token

When a shopper chooses to pay with card, the Card Component renders a switch for saving the card details for future payments. If a shopper selects this option, the `paymentComponentState` from the Component will include `data.storePaymentMethod`. Pass this to your server.

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

* `storePaymentMethod`: The `paymentComponentState.data.storePaymentMethod` from your client app.
* [shopperReference](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments#request-shopperReference): Your unique identifier for the shopper.

If you do not want to show the switch for saving card details, set `showStoredPaymentMethods` to **false** when [creating the `cardConfiguration` object](#create-card-configuration):

```kotlin
     val cardConfiguration = CardConfiguration.Builder(context, "YOUR_CLIENT_KEY")
          // hides the switch for saving card details
          .setShowStorePaymentField(false)
          .build()
```

### Show a stored card in your payment form

When the shopper proceeds to pay, the Component returns the `paymentComponentState.data.paymentMethod`.

1. Pass the `paymentComponentState.data.paymentMethod` to your server.

2. From your server, make a [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) request, specifying:

   * `paymentMethod`: The `paymentComponentState.data.paymentMethod` from your client app.

   **Make a payment with a token**

You can also use tokens to make shopper-not-present payments for subscriptions or contracts. For more information, refer to [Making a payment for a subscription or contract](/online-payments/tokenization/make-token-payments#make-a-subscription-or-unscheduled-card-on-file-payment).

## Test and go live

If your client-side integration isn't ready, you can [test API requests with encrypted card details](/development-resources/test-cards-and-credentials/test-card-numbers#test-encrypted-card-details) by adding a `test_` prefix to the test card details.

Before making live card payments:

1. Test your integration using our [test card numbers](/development-resources/test-cards-and-credentials/test-card-numbers). You can check the status of test payments in your [Customer Area](https://ca-test.adyen.com/) > **Transactions** > **Payments**.

2. [Add the cards that you want to accept](/payment-methods/add-payment-methods) in your [live Customer Area](https://ca-live.adyen.com/).

3. Configure the Component using the [client key](/development-resources/client-side-authentication) from your [live Customer Area](https://ca-live.adyen.com/).

4. Before you can start accepting card payments in the live environment, you need to assess your PCI DSS compliance and submit the required *Self-Assessment Questionnaire A* document. For more information, refer to [PCI DSS compliance guide](/development-resources/pci-dss-compliance-guide#mobile-in-app-online-payments-integration).
