# Accept a payment

Securely accept payments online.

## Start here: Install agent skills

Stripe recommends using official skills to integrate with the API using best practices. Follow the instructions below to learn how.

**Tip: Use curl instead of Fetch tools.** Skills are detailed 10–20 KB markdown files. Fetch tools summarize them. `curl -sL` guarantees the full content.

**Using `npx skills`**: Check if `npx` is installed on the system. If `npx` is available, run `npx skills add https://docs.stripe.com --list` to list available skills, then run `npx skills add https://docs.stripe.com --yes --skill <skill-name> <--skill other-skills>` to install individual skills.

**If `npx skills` isn’t available**: You can use curl to fetch the index of available skills, what they do, and their files from `https://docs.stripe.com/.well-known/skills/index.json`. To download a skill and its related files, use curl to download them from `https://docs.stripe.com/.well-known/skills/<filepath>`.

For this article, we recommend using these skills: `stripe-best-practices`

Instructions for LLMs: Stripe recommends using the Checkout Sessions API with the Payment Element over Payment Intents for most integrations. Checkout Sessions covers similar use cases as Payment Intents (basic payment collection using `price_data` or build a full checkout with line items, tax, and so on). Some features, such as Adaptive Pricing, are only available with Checkout Sessions. Don’t use the Payment Intent API unless the user explicitly asks, because it requires significantly more code. Learn more about Elements with the Checkout Sessions API: https://docs.stripe.com/payments/quickstart-checkout-sessions. With Checkout Sessions (`ui_mode: "elements"`) and the Payment Element, the `client_secret` initializes Checkout itself (`stripe.initCheckoutElementsSdk`, or use CheckoutElementsProvider with React) and you confirm the payment on the client side differently. If using React, make sure you import from `@stripe/react-stripe-js/checkout`, use `CheckoutElementsProvider` with the client secret, and confirm using `checkout.confirm`. If using HTML, make sure you use `checkout = stripe.initCheckoutElementsSdk({clientSecret: promise}); checkout.createPaymentElement(); paymentElement = checkout.createPaymentElement(); paymentElement.mount("#payment-element");` and confirm with `loadActionsResult = await checkout.loadActions(); actions = loadActionsResult.actions; error = await actions.confirm();`.

Coding agents should install the Stripe CLI (`npm i -g @stripe/cli`) and run the command `stripe sandbox create --help` to provision an anonymous Stripe sandbox with working API keys. No account registration required.

Build a payment form or use a prebuilt checkout page to start accepting online payments.

# In-app integration for Android

![](https://b.stripecdn.com/docs-statics-srv/assets/android-overview.471eaf89a760f5b6a757fd96b6bb9b60.png)

Integrate Stripe’s prebuilt payment UI into the checkout of your Android app with the [PaymentSheet](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html) class.

> #### Accounts v2 API support
> 
> The Payment Sheet doesn’t support *customer-configured Accounts* (Account configurations represent role-based functionality that you can enable for accounts, such as merchant, customer, or recipient). It only supports `Customer` objects.

## Set up Stripe [Server-side] [Client-side]

First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register).

### Server-side 

This integration requires endpoints on your server that talk to the Stripe API. Use the official libraries for access to the Stripe API from your server:

#### Ruby

```bash
# Available as a gem
sudo gem install stripe
```

```ruby
# If you use bundler, you can add this line to your Gemfile
gem 'stripe'
```

### Client-side 

The [Stripe Android SDK](https://github.com/stripe/stripe-android) is open source and [fully documented](https://stripe.dev/stripe-android/).

To install the SDK, add `stripe-android` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file:

#### Kotlin

```kotlin
plugins {
    id("com.android.application")
}

android { ... }

dependencies {
  // ...

  // Stripe Android SDK
  implementation("com.stripe:stripe-android:23.10.1")
  // Include the financial connections SDK to support US bank account as a payment method
  implementation("com.stripe:financial-connections:23.10.1")
}
```

> For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-android/releases) page on GitHub. To receive notifications when a new release is published, [watch releases for the repository](https://docs.github.com/en/github/managing-subscriptions-and-notifications-on-github/configuring-notifications#configuring-your-watch-settings-for-an-individual-repository).

## Enable payment methods

View your [payment methods settings](https://dashboard.stripe.com/settings/payment_methods) and enable the payment methods you want to support. You need at least one payment method enabled to create a *PaymentIntent* (The Payment Intents API tracks the lifecycle of a customer checkout flow and triggers additional authentication steps when required by regulatory mandates, custom Radar fraud rules, or redirect-based payment methods).

By default, Stripe enables cards and other prevalent payment methods that can help you reach more customers, but we recommend turning on additional payment methods that are relevant for your business and customers. See [Payment method support](https://docs.stripe.com/payments/payment-methods/payment-method-support.md) for product and payment method support, and our [pricing page](https://stripe.com/pricing/local-payment-methods) for fees.

## Add an endpoint [Server-side]

> #### Note
> 
> To display the PaymentSheet before you create a PaymentIntent, see [Collect payment details before creating an Intent](https://docs.stripe.com/payments/accept-a-payment-deferred.md?type=payment).

This integration uses three Stripe API objects:

1. [PaymentIntent](https://docs.stripe.com/api/payment_intents.md): Stripe uses this to represent your intent to collect payment from a customer, tracking your charge attempts and payment state changes throughout the process.

2. (Optional) A [customer-configured Account](https://docs.stripe.com/api/v2/core/accounts/object.md#v2_account_object-applied_configurations) or a [Customer](https://docs.stripe.com/api/customers.md) object: To set up a payment method for future payments, you must attach it to a customer. Create an object to represent your customer when they create an account with your business. If your customer makes a payment as a guest, you can create an `Account` or `Customer` object before payment and associate it with your own internal representation of the customer’s account later.

3. (Optional) [CustomerSession](https://docs.stripe.com/api/customer_sessions.md): Information on the object that represents your customer is sensitive, and can’t be retrieved directly from an app. A `CustomerSession` grants the SDK temporary scoped access to the `Account` or `Customer` and provides additional configuration options. See a complete list of [configuration options](https://docs.stripe.com/api/customer_sessions/create.md#create_customer_session-components).

> If you never save cards for customers and don’t allow returning customers to reuse saved cards, you can omit the `Account` or `Customer` object and the `CustomerSession` object from your integration.

For security reasons, your app can’t create these objects. Instead, add an endpoint on your server that:

1. Retrieves the `Account` or `Customer`, or creates a new one.
2. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the `Account` or `Customer`.
3. Creates a `PaymentIntent` with the [amount](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-amount), [currency](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-currency), and either the [customer_account](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer_account) or the [customer](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer).
4. Returns the `PaymentIntent`’s *client secret* (The client secret is a unique key returned from Stripe as part of a PaymentIntent. This key lets the client access important fields from the PaymentIntent (status, amount, currency) while hiding sensitive ones (metadata, customer)), the `CustomerSession`’s `client_secret`, the ID of the `Account` or `Customer`, and your [publishable key](https://dashboard.stripe.com/apikeys) to your app.

The payment methods shown to customers during the checkout process are also included on the PaymentIntent. You can let Stripe pull payment methods from your Dashboard settings or you can list them manually. Regardless of the option you choose, know that the currency passed in the PaymentIntent filters the payment methods shown to the customer. For example, if you pass `eur` on the PaymentIntent and have OXXO enabled in the Dashboard, OXXO won’t be shown to the customer because OXXO doesn’t support `eur` payments.

Unless your integration requires a code-based option for offering payment methods, Stripe recommends the automated option. This is because Stripe evaluates the currency, payment method restrictions, and other parameters to determine the list of supported payment methods. Payment methods that increase conversion and that are most relevant to the currency and customer’s location are prioritized.

#### Manage payment methods from the Dashboard

You can manage payment methods from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods). Stripe handles the return of eligible payment methods based on factors such as the transaction’s amount, currency, and payment flow. The PaymentIntent is created using the payment methods you configured in the Dashboard. If you don’t want to use the Dashboard or if you want to specify payment methods manually, you can list them using the `payment_method_types` attribute.

#### curl

```bash
# Create a Customer (use an existing Customer ID if this is a returning customer)
curl https://api.stripe.com/v1/customers \
  -u <<YOUR_SECRET_KEY>>: \
  -X "POST" \
  -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}"

# Create an CustomerSession for the Customer
curl https://api.stripe.com/v1/customer_sessions \
  -u <<YOUR_SECRET_KEY>>: \
  -X "POST" \
  -d "customer"="{{CUSTOMER_ID}}" \
  -d "components[mobile_payment_element][enabled]"=true \
  -d "components[mobile_payment_element][features][payment_method_save]"=enabled \
  -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \
  -d "components[mobile_payment_element][features][payment_method_remove]"=enabled

# Create a PaymentIntent

  -d "customer"="{{CUSTOMER_ID}}" \
  -d "amount"=1099 \
  -d "currency"="eur" \

  -d "automatic_payment_methods[enabled]"=true \
```

#### Listing payment methods manually

#### curl

```bash
# Create a Customer (use an existing Customer ID if this is a returning customer)
curl https://api.stripe.com/v1/customers \
  -u <<YOUR_SECRET_KEY>>: \
  -X "POST" \
  -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}"

# Create an CustomerSession for the Customer
curl https://api.stripe.com/v1/customer_sessions \

  -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \
  -d "components[mobile_payment_element][features][payment_method_remove]"=enabled

# Create a PaymentIntent
curl https://api.stripe.com/v1/payment_intents \
  -u <<YOUR_SECRET_KEY>>: \
  -X "POST" \
  -d "customer"="{{CUSTOMER_ID}}" \
  -d "amount"=1099 \
  -d "currency"="eur" \
  -d "payment_method_types[]"="bancontact" \
  -d "payment_method_types[]"="card" \
  -d "payment_method_types[]"="ideal" \
  -d "payment_method_types[]"="klarna" \
  -d "payment_method_types[]"="sepa_debit" \
```

> Each payment method needs to support the currency passed in the PaymentIntent and your business needs to be based in one of the countries each payment method supports. See the [Payment method integration options](https://docs.stripe.com/payments/payment-methods/integration-options.md) page for more details about what’s supported.

## Collect payment details [Client-side]

Before displaying the mobile Payment Element, your checkout page should:

- Show the products being purchased and the total amount
- Collect any required shipping information using the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=android)
- Include a checkout button to present Stripe’s UI

#### Jetpack Compose

[Initialize](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-builder/index.html) a `PaymentSheet` instance inside `onCreate` of your checkout Activity, passing a method to handle the result.

```kotlin
import androidx.compose.runtime.Composable
import androidx.compose.runtime.remember
import com.stripe.android.paymentsheet.PaymentSheet
import com.stripe.android.paymentsheet.PaymentSheetResult

@Composable
fun App() {
  val paymentSheet = remember { PaymentSheet.Builder(::onPaymentSheetResult).build() }
}

private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {
  // implemented in the next steps
}
```

Next, fetch the PaymentIntent client secret, Customer Session client secret, Customer ID, and publishable key from the endpoint you created in the previous step. Set the publishable key using `PaymentConfiguration` and store the others for use when you present the PaymentSheet.

```kotlin
import androidx.compose.runtime.Composable
import androidx.compose.runtime.rememberimport androidx.compose.runtime.LaunchedEffect
import androidx.compose.runtime.getValue
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.setValue
import androidx.compose.ui.platform.LocalContext
import com.stripe.android.PaymentConfiguration
import com.stripe.android.paymentsheet.PaymentSheet
import com.stripe.android.paymentsheet.PaymentSheetResult

@Composable
fun App() {
  val paymentSheet = remember { PaymentSheet.Builder(::onPaymentSheetResult) }.build()val context = LocalContext.current
  var customerConfig by remember { mutableStateOf<PaymentSheet.CustomerConfiguration?>(null) }
  varpaymentIntentClientSecret by remember { mutableStateOf<String?>(null) }

  LaunchedEffect(context) {
    // Make a request to your own server and retrieve payment configurations
    val networkResult = ...
    if (networkResult.isSuccess) {paymentIntentClientSecret = networkResult.paymentIntent
        customerConfig = PaymentSheet.CustomerConfiguration.createWithCustomerSession(
          id = networkResult.customer,
          clientSecret = networkResult.customerSessionClientSecret
        )PaymentConfiguration.init(context, networkResult.publishableKey)}
  }
}

private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {
  // implemented in the next steps
}
```

When the customer taps your checkout button, call [presentWithPaymentIntent](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html#1814490530%2FFunctions%2F2002900378) to present the payment sheet. After the customer completes the payment, the sheet dismisses and the [PaymentSheetResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html) is called with a [PaymentSheetResult](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result/index.html).

        customerConfig = PaymentSheet.CustomerConfiguration.createWithCustomerSession(
          id = networkResult.customer,
          clientSecret = networkResult.customerSessionClientSecret
        )
        PaymentConfiguration.init(context, networkResult.publishableKey)
    }
  }Button(
    onClick = {
      val currentConfig = customerConfig
      val currentClientSecret =paymentIntentClientSecret

      if (currentConfig != null && currentClientSecret != null) {
        presentPaymentSheet(paymentSheet, currentConfig, currentClientSecret)
      }
    }
  ) {
    Text("Checkout")
  }
}private fun presentPaymentSheet(
  paymentSheet: PaymentSheet,
  customerConfig: PaymentSheet.CustomerConfiguration,paymentIntentClientSecret: String
) {
  paymentSheet.presentWithPaymentIntent(paymentIntentClientSecret,
    PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name")
      .customer(customerConfig)
      // Set `allowsDelayedPaymentMethods` to true if your business handles
      // delayed notification payment methods like US bank accounts.
      .allowsDelayedPaymentMethods(true)
      .build()
  )
}
private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {when(paymentSheetResult) {
    is PaymentSheetResult.Canceled -> {
      print("Canceled")
    }
    is PaymentSheetResult.Failed -> {
      print("Error: ${paymentSheetResult.error}")
    }
    is PaymentSheetResult.Completed -> {
      // Display for example, an order confirmation screen
      print("Completed")
    }
  }
}
```

#### Views (Classic)

[Initialize](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html#-394860221%2FConstructors%2F2002900378) a `PaymentSheet` instance inside `onCreate` of your checkout Activity, passing a method to handle the result.

#### Kotlin

```kotlin
import com.stripe.android.paymentsheet.PaymentSheet

class CheckoutActivity : AppCompatActivity() {
  lateinit var paymentSheet: PaymentSheet

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    paymentSheet = PaymentSheet.Builder(::onPaymentSheetResult).build(this)
  }

  fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {
    // implemented in the next steps
  }
}
```

Next, fetch the PaymentIntent client secret, Customer Session client secret, Customer ID, and publishable key from the endpoint you created in the previous step. Set the publishable key using `PaymentConfiguration` and store the others for use when you present the PaymentSheet.

#### Kotlin

```kotlin
import com.stripe.android.paymentsheet.PaymentSheet

class CheckoutActivity : AppCompatActivity() {
  lateinit var paymentSheet: PaymentSheetlateinit var customerConfig: PaymentSheet.CustomerConfiguration
  lateinit varpaymentIntentClientSecret: String

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    paymentSheet = PaymentSheet.Builder(::onPaymentSheetResult).build(this)lifecycleScope.launch {
      // Make a request to your own server and retrieve payment configurations
      val networkResult = MyBackend.getPaymentConfig()
      if (networkResult.isSuccess) {paymentIntentClientSecret = networkResult.paymentIntent
        customerConfig = PaymentSheet.CustomerConfiguration.createWithCustomerSession(
          id = networkResult.customer,
          clientSecret = networkResult.customerSessionClientSecret
        )PaymentConfiguration.init(context, networkResult.publishableKey)}
    }
  }

  fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {
    // implemented in the next steps
  }
}
```

When the customer taps your checkout button, call [presentWithPaymentIntent](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html#1814490530%2FFunctions%2F2002900378) to present the payment sheet. After the customer completes the payment, the sheet dismisses and the [PaymentSheetResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html) is called with a [PaymentSheetResult](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result/index.html).

#### Kotlin

```kotlin
// ...
class CheckoutActivity : AppCompatActivity() {
  lateinit var paymentSheet: PaymentSheet
  lateinit var customerConfig: PaymentSheet.CustomerConfiguration
  lateinit var paymentIntentClientSecret: String
  // ...fun presentPaymentSheet() {
    paymentSheet.presentWithPaymentIntent(paymentIntentClientSecret,
      PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name")
        .customer(customerConfig)
        // Set `allowsDelayedPaymentMethods` to true if your business handles
        // delayed notification payment methods like US bank accounts.
        .allowsDelayedPaymentMethods(true)
        .build()
    )
  }

  fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {when(paymentSheetResult) {
      is PaymentSheetResult.Canceled -> {
        print("Canceled")
      }
      is PaymentSheetResult.Failed -> {
        print("Error: ${paymentSheetResult.error}")
      }
      is PaymentSheetResult.Completed -> {
        // Display for example, an order confirmation screen
        print("Completed")
      }
    }
  }
}
```

Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful.

## Handle post-payment events [Server-side]

Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the [Dashboard webhook tool](https://dashboard.stripe.com/webhooks) or follow the [webhook guide](https://docs.stripe.com/webhooks/quickstart.md) to receive these events and run actions, such as sending an order confirmation email to your customer, logging the sale in a database, or starting a shipping workflow.

Listen for these events rather than waiting on a callback from the client. On the client, the customer could close the browser window or quit the app before the callback executes, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events is what enables you to accept [different types of payment methods](https://stripe.com/payments/payment-methods-guide) with a single integration.

In addition to handling the `payment_intent.succeeded` event, we recommend handling these other events when collecting payments with the Payment Element:

| Event                                                                                                                           | Description                                                                                                                                                                                                                                                                         | Action                                                                                                                                                                                           |

See [Testing](https://docs.stripe.com/testing.md) for additional information to test your integration.

## Optional: Enable Link

Enable Link in your [Payment Method settings](https://dashboard.stripe.com/settings/payment_methods) to allow your customers to securely save and reuse their payment information using Link’s one-click express checkout button.

### Pass your customer’s email to the Mobile Payment Element

Link authenticates a customer using their email address. Stripe recommends prefilling as much information as possible to streamline the checkout process.

To prefill the customer’s name, email address, and phone number, supply `defaultBillingDetails` with your customer information when initializing `PaymentSheet.Configuration`.

#### Kotlin

```kotlin
val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "Example, Inc.")
  .defaultBillingDetails(
    PaymentSheet.BillingDetails(
        name = "Jenny Rosen",
        email = "jenny.rosen@example.com",
        phone = "888-888-8888"
    )
  )
  .build()
```

### Handle user logout

`PaymentSheet` stores some information locally to remember whether a user has used Link within an app. To clear the internal state of `PaymentSheet`, call the `PaymentSheet.resetCustomer()` method when your user logs out.

#### Kotlin

```kotlin
class MyActivity: Activity {

  fun onLogoutButtonClicked() {
    PaymentSheet.resetCustomer(this)
    // Other logout logic required by your app
  }
}
```

## Optional: Enable Google Pay

### Set up your integration

To use Google Pay, first enable the Google Pay API by adding the following to the `<application>` tag of your **AndroidManifest.xml**:

```xml
<application>
  ...
  <meta-data
    android:name="com.google.android.gms.wallet.api.enabled"
    android:value="true" />
</application>
```

For more details, see Google Pay’s [Set up Google Pay API](https://developers.google.com/pay/api/android/guides/setup) for Android.

### Add Google Pay

To add Google Pay to your integration, pass a [PaymentSheet.GooglePayConfiguration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-google-pay-configuration/index.html) with your Google Pay environment (production or test) and the [country code of your business](https://dashboard.stripe.com/settings/account) when initializing [PaymentSheet.Configuration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html).

#### Kotlin

```kotlin
val googlePayConfiguration = PaymentSheet.GooglePayConfiguration(
  environment = PaymentSheet.GooglePayConfiguration.Environment.Test,
  countryCode = "US",
  currencyCode = "USD" // Required for Setup Intents, optional for Payment Intents
)
val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name")
  .googlePay(googlePayConfiguration)
  .build()
```

### Test Google Pay

Google allows you to make test payments through their [Test card suite](https://developers.google.com/pay/api/android/guides/resources/test-card-suite). The test suite supports using Stripe [test cards](https://docs.stripe.com/testing.md).

You must test Google Pay using a physical Android device instead of a simulated device, in a country where Google Pay is supported. Log in to a Google account on your test device with a real card saved to Google Wallet.

## Optional: Enable card scanning

To enable card scanning support, [request production access](https://developers.google.com/pay/api/android/guides/test-and-deploy/request-prod-access) to the Google Pay API from the [Google Pay and Wallet Console](https://pay.google.com/business/console?utm_source=devsite&utm_medium=devsite&utm_campaign=devsite).

- If you’ve enabled Google Pay, the card scanning feature is automatically available in our UI on eligible devices. To learn more about eligible devices, see the [Google Pay API constraints](https://developers.google.com/pay/payment-card-recognition/debit-credit-card-recognition)
- **Important:** The card scanning feature only appears in builds signed with the same signing key registered in the [Google Pay & Wallet Console](https://pay.google.com/business/console). Test or debug builds using different signing keys (for example, builds distributed through Firebase App Tester) won’t show the **Scan card** option. To test card scanning in pre-release builds, you must either:
  - Sign your test builds with your production signing key
  - Add your test signing key fingerprint to the Google Pay and Wallet Console

If your app doesn’t support Google Pay, you can use the Stripe card scanner.

> The Stripe card scanner is in public preview.

To enable card scanning support, add `stripecardscan` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file:

#### Groovy

```groovy
implementation 'com.stripe:stripecardscan:23.10.1'
```

## Optional: Enable ACH payments

To enable ACH debit payments include Financial Connections as a dependency for your app.

The [Stripe Android SDK](https://github.com/stripe/stripe-android) is open source and [fully documented](https://stripe.dev/stripe-android/).

To install the SDK, add `financial-connections` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file:

#### Kotlin

```kotlin
plugins {
    id("com.android.application")
}

android { ... }

dependencies {
  // ...

  // Financial Connections Android SDK
  implementation("com.stripe:financial-connections:23.10.1")
}
```

> For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-android/releases) page on GitHub. To receive notifications when a new release is published, [watch releases for the repository](https://docs.github.com/en/github/managing-subscriptions-and-notifications-on-github/configuring-notifications#configuring-your-watch-settings-for-an-individual-repository).

## Optional: Customize the sheet

All customization is configured using the [PaymentSheet.Configuration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html) object.

### Appearance

Customize colors, fonts, and more to match the look and feel of your app by using the [appearance API](https://docs.stripe.com/elements/appearance-api/mobile.md?platform=android).

### Payment method layout

Configure the layout of payment methods in the sheet using [paymentMethodLayout](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/-builder/index.html#2123253356%2FFunctions%2F2002900378). You can display them horizontally, vertically, or let Stripe optimize the layout automatically.
![](https://b.stripecdn.com/docs-statics-srv/assets/android-mpe-payment-method-layouts.3bcfe828ceaad1a94e0572a22d91733f.png)

#### Kotlin

```kotlin
PaymentSheet.Configuration.Builder("Example, Inc.")
  .paymentMethodLayout(PaymentSheet.PaymentMethodLayout.Automatic)
  .build()
```

### Collect users addresses

Collect local and international shipping or billing addresses from your customers using the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=android).

### Business display name

Specify a customer-facing business name by setting [merchantDisplayName](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html#-191101533%2FProperties%2F2002900378). By default, this is your app’s name.

#### Kotlin

```kotlin
PaymentSheet.Configuration.Builder(
  merchantDisplayName = "My app, Inc."
).build()
```

### Dark mode

By default, `PaymentSheet` automatically adapts to the user’s system-wide appearance settings (light and dark mode). You can change this by setting light or dark mode on your app:

#### Kotlin

```kotlin
// force dark
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
// force light
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)
```

### Default billing details

To set default values for billing details collected in the payment sheet, configure the `defaultBillingDetails` property. The `PaymentSheet` pre-populates its fields with the values that you provide.

#### Kotlin

```kotlin
val address = PaymentSheet.Address(country = "US")
val billingDetails = PaymentSheet.BillingDetails(
  address = address,
  email = "foo@bar.com"
)
val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "Merchant, Inc.")
  .defaultBillingDetails(billingDetails)
  .build()
```

### Configure collection of billing details

Use `BillingDetailsCollectionConfiguration` to specify how you want to collect billing details in the PaymentSheet.

You can collect your customer’s name, email, phone number, and address.

If you want to attach default billing details to the PaymentMethod object even when those fields aren’t collected in the UI, set `billingDetailsCollectionConfiguration.attachDefaultsToPaymentMethod` to `true`.

#### Kotlin

```kotlin
val billingDetails = PaymentSheet.BillingDetails(
  email = "foo@bar.com"
)
val billingDetailsCollectionConfiguration = BillingDetailsCollectionConfiguration(
  attachDefaultsToPaymentMethod = true,
  name = BillingDetailsCollectionConfiguration.CollectionMode.Always,
  email = BillingDetailsCollectionConfiguration.CollectionMode.Never,
  address = BillingDetailsCollectionConfiguration.AddressCollectionMode.Full,
)
val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "Merchant, Inc.")
  .defaultBillingDetails(billingDetails)
  .billingDetailsCollectionConfiguration(billingDetailsCollectionConfiguration)
  .build()
```

> Consult with your legal counsel regarding laws that apply to collecting information. Only collect phone numbers if you need them for the transaction.

## Optional: Complete payment in your UI

You can present Payment Sheet to only collect payment method details and complete the payment back in your app’s UI. This is useful if you have a custom buy button or require additional steps after payment details are collected.
![](https://b.stripecdn.com/docs-statics-srv/assets/android-multi-step.84d8a0a44b1baa596bda491322b6d9fd.png)

> A sample integration is [available on our GitHub](https://github.com/stripe/stripe-android/blob/master/paymentsheet-example/src/main/java/com/stripe/android/paymentsheet/example/samples/ui/paymentsheet/custom_flow/CustomFlowActivity.kt).

1. First, initialize [PaymentSheet.FlowController](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html) instead of `PaymentSheet` using one of the [Builder](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/-builder/index.html) methods.

#### Android (Kotlin)

```kotlin
class CheckoutActivity : AppCompatActivity() {
  private lateinit var flowController: PaymentSheet.FlowController

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    val flowController = PaymentSheet.FlowController.Builder(
      resultCallback = ::onPaymentSheetResult,
      paymentOptionResultCallback = ::onPaymentOption,
    ).build(this)
  }
}
```

1. Next, call `configureWithPaymentIntent` with the Stripe object keys fetched from your backend and update your UI in the callback using [getPaymentOption()](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#-2091462043%2FFunctions%2F2002900378). This contains an image and label representing the customer’s currently selected payment method.

#### Android (Kotlin)

```kotlin
flowController.configureWithPaymentIntent(
  paymentIntentClientSecret = paymentIntentClientSecret,
  configuration = PaymentSheet.Configuration.Builder("Example, Inc.")
    .customer(PaymentSheet.CustomerConfiguration(
      id = customerId,
      ephemeralKeySecret = ephemeralKeySecret
    ))
    .build()
) { isReady, error ->
  if (isReady) {
    // Update your UI using `flowController.getPaymentOption()`
  } else {
    // handle FlowController configuration failure
  }
}
```

1. Next, call [presentPaymentOptions](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#449924733%2FFunctions%2F2002900378) to collect payment details. When the customer finishes, the sheet is dismissed and calls the [paymentOptionCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-option-callback/index.html) passed earlier in `create`. Implement this method to update your UI with the returned `paymentOption`.

#### Android (Kotlin)

```kotlin
// ...
  flowController.presentPaymentOptions()
// ...
  private fun onPaymentOption(paymentOptionResult: PaymentOptionResult) {
    val paymentOption = paymentOptionResult.paymentOption
    if (paymentOption != null) {
      paymentMethodButton.text = paymentOption.label
      paymentMethodButton.setCompoundDrawablesRelativeWithIntrinsicBounds(
        paymentOption.drawableResourceId,
        0,
        0,
        0
      )
    } else {
      paymentMethodButton.text = "Select"
      paymentMethodButton.setCompoundDrawablesRelativeWithIntrinsicBounds(
        null,
        null,
        null,
        null
      )
    }
  }
```

1. Finally, call [confirm](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#-479056656%2FFunctions%2F2002900378) to complete the payment. When the customer finishes, the sheet is dismissed and calls the [paymentResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html#237248767%2FFunctions%2F2002900378) passed earlier in `create`.

#### Android (Kotlin)

```kotlin
  // ...
    flowController.confirmPayment()
  // ...

  private fun onPaymentSheetResult(
    paymentSheetResult: PaymentSheetResult
  ) {
    when (paymentSheetResult) {
      is PaymentSheetResult.Canceled -> {
        // Payment canceled
      }
      is PaymentSheetResult.Failed -> {
        // Payment Failed. See logcat for details or inspect paymentSheetResult.error
      }
      is PaymentSheetResult.Completed -> {
        // Payment Complete
      }
    }
  }
```

Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful.

## Optional: Enable CVC recollection on confirmation

The following instructions for re-collecting the CVC of a saved card during PaymentIntent confirmation assume that your integration includes the following:

- Creation of PaymentIntents before collecting payment details

### Update parameters of the intent creation

To re-collect the CVC when confirming payment, include `require_cvc_recollection` during the creation of the PaymentIntent.

#### curl
