Accept Payments with Apple Pay and Android Pay using the Payment Request API.

Implementation of W3C Payment Request API(version 08 September 2022) for React Native.

Currently not all the features described for the browsers are supported by this lib. Please feel free to open a PR. See TODO

This library represents a significant improvement over the fantastic react-native-payments library, with the following enhancements:

  • Complete Rewrite: The library has undergone a comprehensive refactoring and is now fully written in TypeScript.
  • Native Type Support: We have introduced native types for both IOS and Android, ensuring full typing and detailed documentation.
  • Unified API: With the aim of simplifying usage, the library now offers a unified API for both IOS and Android. You will no longer need code-dependent logic when utilizing the library, thanks to unified interfaces/enums/types.
  • Enhanced Native Code: The IOS and JAVA native code has been thoroughly updated, refactored, and simplified. All deprecated code has been removed, ensuring better performance and stability.
  • Streamlined Gateway Support: While Stripe/Braintree built-in gateway support has been removed, we continue to support custom gateways. The removal of built-in gateway support enables us to focus on providing better integration for custom solutions, especially since Stripe and Braintree already have their dedicated libraries.
  • ReactNative's New Architecture: The library now supports Turbo Modules., ensuring compatibility with ReactNative's latest architecture.

These enhancements ensure that the library is more efficient, maintainable, and future-proof, offering a seamless payment integration experience for your applications.

Features

  • Streamlined. Say goodbye to complicated checkout forms.
  • Efficient. Accelerate checkouts for higher conversion rates.
  • Forward-looking. Utilize a W3C Standards API endorsed by major companies such as Google, Firefox, and more.
  • Versatile. Share payment code seamlessly across iOS, Android, and web applications.

    implementation 'com.google.android.gms:play-services-wallet:19.2.0'

Usage

Detailed guide should be found at:

The PaymentRequest class is designed to facilitate the integration of payment processing into your React Native application. It leverages TypeScript for robust typing and ensures seamless payment experiences across both iOS and Android platforms. Below is a comprehensive guide on how to use the PaymentRequest class effectively:

1. Importing the class

import {PaymentRequest} from '@rnw-community/react-native-payments';

2. Creating an Instance

import { PaymentMethodNameEnum, SupportedNetworkEnum } from "@rnw-community/react-native-payments/src";

const methodData = [
    // ApplePay example
    {
        supportedMethods: PaymentMethodNameEnum.ApplePay,
        data: {
            merchantIdentifier: 'merchant.com.your-app.namespace',
            supportedNetworks: [SupportedNetworkEnum.Visa, SupportedNetworkEnum.MasterCard],
            countryCode: 'US',
            currencyCode: 'USD',
            requestBilling: true,
            requestEmail: true,
            requestShipping: true
        }
    },
    // AndroidPay
    {
        supportedMethods: PaymentMethodNameEnum.AndroidPay,
        data: {
            supportedNetworks: [SupportedNetworkEnum.Visa, SupportedNetworkEnum.MasterCard],
            environment: EnvironmentEnum.Test,
            countryCode: 'DE',
            currencyCode: 'EUR',
            requestBilling: true,
            requestEmail: true,
            requestShipping: true,
            gatewayConfig: {
                gateway: 'example',
                gatewayMerchantId: 'exampleGatewayMerchantId',
            },
        }
    }
];

const paymentDetails = {
    // Provide payment details such as total amount, currency, and other relevant information
};

const paymentRequest = new PaymentRequest(methodData, paymentDetails);

Note: The methodData parameter is an array of PaymentMethodData objects that represent the supported payment methods in your application. Each PaymentMethodData object should have a supportedMethods property specifying the type of payment method (e.g., PaymentMethodNameEnum.AndroidPay or PaymentMethodNameEnum.ApplePay) and a data property containing the corresponding platform-specific data.

2.1 Additional methodData.data options

Depending on the platform and payment method, you can provide additional data to the methodData.data property:

  • environment: This property represents the Android environment for the payment.
  • requestBilling: An optional boolean field that, when present and set to true, indicates that the PaymentResponse will include the billing address of the payer.
  • requestEmail: An optional boolean field that, when present and set to true, indicates that the PaymentResponse will include the email address of the payer.
  • requestShipping: An optional boolean field that, when present and set to true, indicates that the PaymentResponse will include the shipping address of the payer.

3. Checking Payment Capability

Before displaying the payment sheet to the user, you can check if the current device supports the payment methods specified:

const isPaymentPossible = await paymentRequest.canMakePayment();

This method returns a boolean value indicating whether the device supports the specified payment methods.

The PaymentRequest class automatically handles platform-specific payment data based on the provided methodData.

4. Displaying the Payment Sheet

Once you have verified the device's capability, you can proceed to display the payment sheet for the user to complete the transaction:

try {
    const paymentResponse = await paymentRequest.show();
    // Handle the payment response here
} catch (error) {
    // Handle errors or user cancellation
}

// or Promise style
const paymentResponse = paymentRequest.show().then(...).catch(...);

The paymentRequest.show() method returns a promise that resolves with a PaymentResponse object representing the user's payment response.

5. Processing the PaymentResponse

To send all the relevant payment information to the backend (BE) for further processing and validation, you need to extract the required data from the PaymentResponseDetailsInterface object. The PaymentResponseDetailsInterface provides various properties that encompass essential details about the payment, including the payment method used, the payer's information, and transaction-related information.

const paymentResponse = paymentRequest.show().then((paymentResponse) => {
    // This field will have all Android payment token info AndroidPaymentMethodToken
    paymentResponse.androidPayToken;
    // This field will have all IOS payment token info IosPKToken
    paymentResponse.applePayToken;
    // Aditionally if was requested, shipping, billing and payer info would be available
    paymentResponse.billingAddress;
    paymentResponse.payerEmail;
    paymentResponse.payerName;
    paymentResponse.payerPhone;
    paymentResponse.shippingAddress;
    // Send data to your BE
    // Close paymnet sheet
}).catch(...);

The PaymentResponseDetailsInterface includes the following additional properties:

  • billingAddress: This property represents user billing details PaymentResponseAddressInterface and available if was requested in the PaymentRequest.
  • shippingAddress: This property represents user shipping details PaymentResponseAddressInterface and available if was requested in the PaymentRequest.
  • payerEmail: This property represents user email and available if was requested in the PaymentRequest.
  • payerPhone: This property represents user phone and available if was requested in the PaymentRequest.
  • androidPayToken: This property represents PaymentToken information returned by AndroidPay, this should be sent to your payment provider.
  • applePayToken: This property represents PaymentToken information returned by ApplePay, this should be sent to your payment provider.

6. Closing the Payment Sheet

Once the payment process is successfully completed, it's essential to close the payment sheet by calling the PaymentResponse.complete() method. This method takes a parameter from the PaymentComplete enum to indicate the outcome of the payment and hide the payment sheet accordingly.

paymentResponse.complete(PaymentComplete.Success) // OR PaymentComplete.Fail

This will have no affect in the Android platform due to AndroidPay implementation.

7. Aborting the Payment

The PaymentRequset.abort() method in the Payment Request API allows developers to programmatically cancel an ongoing payment request or dismiss the payment sheet when it is in an interactive state. This method is used to handle scenarios where the user decides to cancel the payment process or when specific conditions require the payment request to be aborted.

This will have no affect in the Android platform due to AndroidPay implementation.

Example

You can find working example in the App component of the react-native-payments-example package.
