API Spec
Down below we have a detailed specification for PaymentRequest and instructions for configuring Apple Pay and Google Pay, which is hopefully enough to get you started.
We also have some legacy example projects in the examples
directory that will be rewritten soon and linked above.
Bear with us while we organize things a bit.
Roadmap
Completed
- Apple Pay Stripe
Completed, untested
- Apple Pay Braintree
- Google Pay (Stripe, Braintree)
- Web
In progress
- Stripe: Payment Intents (for SCA)
Planned
- Tutorial docs
Naoufal, the original author of this library, has done a lot of the hard work integrating iOS, Android, Web platforms and Stripe and Braintree gateways.
The library has fallen out of regular maintenance and we're working to test and update all parts to be compatible for RN in the 2020s.
If you're feeling brave give the untested platforms a try and let us know how it worked.

Setting up Apple Pay/Android Pay
Before you can start accepting payments in your App, you'll need to setup Apple Pay and/or Android Pay.
Apple Pay
- Register as an Apple Developer
- Obtain a merchant ID
- Enable Apple Pay in your app
Apple has a documentation on how to do this in their Configuring your Environment guide.
Android Pay
- Add Android Pay and Google Play Services to your dependencies
- Enable Android Pay in your Manifest
Google has documentation on how to do this in their Setup Android Pay guide.
Importing the Library
Once Apple Pay/Android Pay is enabled in your app, jump into your app's entrypoint and make the PaymentRequest
globally available to your app.
// index.ios.js
global.PaymentRequest = require('react-native-payments').PaymentRequest;
Initializing the Payment Request
To initialize a Payment Request, you'll need to provide PaymentMethodData
and PaymentDetails
.
Payment Method Data
The Payment Method Data is where you defined the forms of payment that you accept. To enable Apple Pay, we'll define a supportedMethod
of apple-pay
. We're also required to pass a data
object to configures Apple Pay. This is where we provide our merchant id, define the supported card types and the currency we'll be operating in.
const METHOD_DATA = [{
supportedMethods: ['apple-pay'],
data: {
merchantIdentifier: 'merchant.com.your-app.namespace',
supportedNetworks: ['visa', 'mastercard', 'amex'],
countryCode: 'US',
currencyCode: 'USD'
}
}];
const METHOD_DATA = [{
supportedMethods: ['android-pay'],
data: {
supportedNetworks: ['visa', 'mastercard', 'amex'],
currencyCode: 'USD',
environment: 'TEST', // defaults to production
paymentMethodTokenizationParameters: {
tokenizationType: 'NETWORK_TOKEN',
parameters: {
publicKey: 'your-pubic-key'
}
}
}
}];
Payment Details
Payment Details is where define transaction details like display items, a total and optionally shipping options.
Google has excellent documentation for Defining Payment Details.
const DETAILS = {
id: 'basic-example',
displayItems: [
{
label: 'Movie Ticket',
amount: { currency: 'USD', value: '15.00' }
}
],
total: {
label: 'Merchant Name',
amount: { currency: 'USD', value: '15.00' }
}
};
Once you've defined your methodData
and details
, you're ready to initialize your Payment Request.
const paymentRequest = new PaymentRequest(METHOD_DATA, DETAILS);
🚨 Note: On Android, display items are not displayed within the Android Pay view. Instead, the User Flows documentation suggests showing users a confirmation view where you list the display items. When using React Native Payments, show this view after receiving the PaymentResponse
.
Displaying the Payment Request
Now that you've setup your Payment Request, displaying it is as simple as calling the show
method.
paymentRequest.show();
Aborting the Payment Request
You can abort the Payment Request at any point by calling the abort
method.
paymentRequest.abort();
🚨 Note: Not yet implemented on Android Pay
Requesting Contact Information
Some apps may require contact information from a user. You can do so by providing a PaymentOptions
as a third argument when initializing a Payment Request. Using Payment Options, you can request a contact name, phone number and/or email.
Requesting a Contact Name
Set requestPayerName
to true
to request a contact name.
const OPTIONS = {
requestPayerName: true
};
🚨 Note: On Android, requesting a contact name will present the user with a shipping address selector. If you're not shipping anything to the user, consider capturing the contact name outside of Android Pay.
Requesting a Phone Number
Set requestPayerPhone
to true
to request a phone number.
const OPTIONS = {
requestPayerPhone: true
};
🚨 Note: On Android, requesting a phone number will present the user with a shipping address selector. If you're not shipping anything to the user, consider capturing the phone number outside of Android Pay.
Requesting an Email Address
Set requestPayerEmail
to true
to request an email address.
const OPTIONS = {
requestPayerEmail: true
};
You can also request all three by setting them all to true
.
const OPTIONS = {
requestPayerName: true,
requestPayerPhone: true,
requestPayerEmail: true
};
Requesting a Shipping Address
Requesting a shipping address is done in three steps.
First, you'll need to set requestShipping
to true
within PaymentOptions
.
const OPTIONS = {
requestShipping: true
};
Second, you'll need to include shippingOptions
in your Payment Details.
const DETAILS = {
id: 'basic-example',
displayItems: [
{
label: 'Movie Ticket',
amount: { currency: 'USD', value: '15.00' }
}
],
+ shippingOptions: [{
+ id: 'economy',
+ label: 'Economy Shipping',
+ amount: { currency: 'USD', value: '0.00' },
+ detail: 'Arrives in 3-5 days' // `detail` is specific to React Native Payments
+ }],
total: {
label: 'Merchant Name',
amount: { currency: 'USD', value: '15.00' }
}
};
Lastly, you'll need to register event listeners for when a user selects a shippingAddress
and/or a shippingOption
. In the callback each event, you'll need to provide new PaymentDetails
that will update your PaymentRequest.
paymentRequest.addEventListener('shippingaddresschange', e => {
const updatedDetails = getUpdatedDetailsForShippingAddress(paymentRequest.shippingAddress;
e.updateWith(updatedDetails);
});
paymentRequest.addEventListener('shippingoptionchange', e => {
const updatedDetails = getUpdatedDetailsForShippingOption(paymentRequest.shippingOption);
e.updateWith(updatedDetails);
});
For a deeper dive on handling shipping in Payment Request, checkout Google's Shipping in Payment Request.
🚨 Note: On Android, there are no shippingaddresschange
and shippingoptionchange
events. To allow users to update their shipping address, you'll need to trigger a new PaymentRequest
. Updating shipping options typically happens after the receiving the PaymentResponse
and before calling its getPaymentToken
method.
Processing Payments
Now that we know how to initialize, display, and dismiss a Payment Request, let's take a look at how to process payments.
When a user accepts to pay, PaymentRequest.show
will resolve to a Payment Response.
paymentRequest.show()
.then(paymentResponse => {
// Your payment processing code goes here
return processPayment(paymentResponse);
});
There are two ways to process Apple Pay/Android Pay payments -- on your server or using a payment processor.
Processing Payments on Your Server
If you're equipped to process Apple Pay/Android Pay payments on your server, all you have to do is send the Payment Response data to your server.
⚠️ Note: When running Apple Pay on simulator,
paymentData
equals tonull
.
import { NativeModules } from 'react-native';
paymentRequest.show()
.then(paymentResponse => {
const { transactionIdentifier, paymentData } = paymentResponse.details;
return fetch('...', {
method: 'POST',
body: {
transactionIdentifier,
paymentData
}
})
.then(res => res.json())
.then(successHandler)
.catch(errorHandler)
});
paymentRequest.show()
.then(paymentResponse => {
const { getPaymentToken } = paymentResponse.details;
return getPaymentToken()
.then(paymentToken => {
const { ephemeralPublicKey, encryptedMessage, tag } = paymentResponse.details;
return fetch('...', {
method: 'POST',
body: {
ephemeralPublicKey,
encryptedMessage,
tag
}
})
.then(res => res.json())
.then(successHandler)
.catch(errorHandler)
});
});
You can learn more about server-side decrypting of Payment Tokens on Apple's Payment Token Format Reference documentation.
Processing Payments with a Payment Processor
When using a payment processor, you'll receive a paymentToken
field within the details
of the PaymentResponse
. Use this token to charge customers with your payment processor.
paymentRequest.show()
.then(paymentResponse => {
const { paymentToken } = paymentResponse.details; // On Android, you need to invoke the `getPaymentToken` method to receive the `paymentToken`.
return fetch('...', {
method: 'POST',
body: {
paymentToken
}
})
.then(res => res.json())
.then(successHandler)
.catch(errorHandler);
});
paymentRequest.show()
.then(paymentResponse => {
const { getPaymentToken } = paymentResponse.details;
return getPaymentToken()
.then(paymentToken => fetch('...', {
method: 'POST',
body: {
paymentToken
}
})
.then(res => res.json())
.then(successHandler)
.catch(errorHandler);
});
});
For a list of supported payment processors and how to enable them, see the Add-ons section.
Dismissing the Payment Request
Dismissing the Payment Request is as simple as calling the complete
method on of the PaymentResponse
.
paymentResponse.complete('success'); // Alternatively, you can call it with `fail` or `unknown`
🚨 Note: On Android, there is no need to call paymentResponse.complete
-- the PaymentRequest dismisses itself.
Testing Payments
Apple Pay
The sandbox environment is a great way to test offline implementation of Apple Pay for apps, websites, and point of sale systems. Apple offers detailed guide for setting up sandbox environment.
⚠️ Note: It is also important to test Apple Pay in your production environment. Real cards must be used in the production environment. Test cards will not work.
⚠️ Note: There are known differences when running Apple Pay on simulator and real device. Make sure you test Apple Pay on real device before going into production.
Apple Pay Button
Provides a button that is used either to trigger payments through Apple Pay or to prompt the user to set up a card. Detailed docs and examples
Add-ons
Here's a list of Payment Processors that you can enable via add-ons:
🚨 Note: On Android, Payment Processors are enabled by default.
