@nativescript/apple-pay

A plugin that allows you to offer Apple Pay in your iOS apps.

Installation

ns plugin add @nativescript/apple-pay

Requirements

For Apple Pay to work in your iOS application, you need to complete the following steps. These steps are also outlined in the Apple PassKit documentation.

Create a merchant ID

A Merchant ID is an identifier you register with Apple that uniquely identifies your business as a merchant able to accept payments. This ID never expires and can be used on multiple websites and iOS apps. See Create a merchant identifier for the setup steps.

Create a Payment Processing certificate

The certificate is associated with your merchant ID and used to secure transaction data. Apple Pay servers use the certificate’s public key to encrypt payment data. You (or your payment service provider) use the private key to decrypt the data to process payments. See Create a payment processing certificate for the setup steps.

Enable Apple Pay in Xcode.

Follow the steps Enable Apple Pay.

For a video showing the configuration steps, see: Configuring Your Developer Account for Apple Pay.

Once that configuration is done for your Apple developer account, you will be able to use the PassKit framework for Apple Pay inside your iOS application.

Use @nativescript/apple-pay

Implement Apple Pay

To implement Apple Pay in your app, follow the following steps:

Register the Apple Pay button and add it to your Page.

<ios>
    <ApplePayBtn
        tap="{{ onApplePayTap }}"
        buttonType="InStore"
    ></ApplePayBtn>
</ios>

Handle the button's tap event

export class ApplePayViewModel extends Observable {
  
  constructor(){
    super()
  }

  onApplePayTap() {

  }
}

In the tap event's callback function(onApplePayTap in this exampl), do the following:

Check if Apple Pay is supported by calling isApplePaySupported()

import { isApplePaySupported } from '@nativescript/apple-pay'

if(isApplePaySupported()){

}

Listen to the DidAuthorizePaymentHandler(and AuthorizationDidFinish) event

applePayBtn.once(ApplePayEvents.DidAuthorizePaymentHandler, async (args: AuthorizePaymentEventData) => {
  // 1. Send the user payment data to your payments services provider(PSP)
  // 2. Use the response from the PSP to further process your transation, or
  // close the payment sheet
}
)

The DidAuthorizePaymentHandler event is emitted when a user authorizes the app to make payments with their payment data.
Make a call to your payments services provider(Stripe, PayPal, etc) sending the user's data and other transactional data(AuthorizePaymentEventData object) received from the event.

If Apple Pay is supported, present the user with the payment sheet by calling the createPaymentRequest() method on the ApplePayBtn instance passing it an ApplePayRequest object.

const request = {
				paymentItems,
				merchantId: <Your_Apple_Pay_Merchant_ID>, // the merchant ID for this app
				merchantCapabilities: ApplePayMerchantCapability.ThreeDS,
				countryCode: 'US',
				currencyCode: 'USD',
				shippingContactFields: [ApplePayContactFields.Name, ApplePayContactFields.PostalAddress],
				billingContactFields: [ApplePayContactFields.Name, ApplePayContactFields.PostalAddress],
				supportedNetworks: [ApplePayNetworks.Amex, ApplePayNetworks.Visa, ApplePayNetworks.Discover, ApplePayNetworks.MasterCard],
			} as ApplePayRequest;

await applePayBtn.createPaymentRequest(request).catch((err) => {
				console.log('Apple Pay Error', err);
			  });
