React Native Stripe Checkout

React Native implementation for Stripe.js Checkout.

Description

The library allows you to use Stripe.js Checkout with react-native without ejecting. You can use it with both server-side implementations and client-side implementations. Simply ensure you follow the url structure guidelines below.

Prequisites

• This library relies on React Native Webview. Please follow this guide to install in your project first.

Installation

• Ensure you've completed the setps in prequisites.

• Install package via npm or yarn:

npm install --save react-native-stripe-checkout-webview OR yarn add react-native-stripe-checkout-webview

• Import in your project

import StripeCheckout from 'react-native-stripe-checkout-webview';

Usage

import StripeCheckout from 'react-native-stripe-checkout-webview';

type Props = { STRIPE_PUBLIC_KEY: string, CHECKOUT_SESSION_ID: string };

const MyStripeCheckout = ({ STRIPE_PUBLIC_KEY, CHECKOUT_SESSION_ID }: Props) => (
  <StripeCheckout
    stripePublicKey={STRIPE_PUBLIC_KEY}
    checkoutSessionInput={{
      sessionId: CHECKOUT_SESSION_ID,
    }}
    onSuccess={({ checkoutSessionId }) => {
      console.log(`Stripe checkout session succeeded. session id: ${checkoutSessionId}.`);
    }}
    onCancel={() => {
      console.log(`Stripe checkout session cancelled.`);
    }}
  />
);

export default MyStripeCheckout;

Important Notes about URLs

• successUrl must have the query string params ?sc_checkout=success&sc_sid={CHECKOUT_SESSION_ID}
• sc_sid is optional - must be the last param - when passed results in sessionId being passed to the onSuccess function
• cancelUrl must have the query string params ?sc_checkout=cancel
• A simple way to do this is using url-join. eg: urlJoin(mySuccessUrl, '?sc_checkout=success&sc_sid={CHECKOUT_SESSION_ID}').

Component props

• stripePublicKey (String) - Stripe public key of your project.
• checkoutSessionInput (Object) - Object to be passed to Stripe's redirectToCheckout function. Docs.
• js // Server-side Checkout Session flow { sessionId: string, // optional client-side locale hint - see "A note on locale" below locale?: string, } // Client-only flow | { clientReferenceId: string, successUrl: string, cancelUrl: string, items?: Array<{ plan: string, quantity: string }>, lineItems?: Array<{ price: number, quantity: number }>, mode?: 'payment' | 'subscription', submitType?: string, // common customerEmail?: string, billingAddressCollection?: 'required' | 'auto', shippingAddressCollection?: { allowedCountries: Array<string>, }, locale?: string, }
• When using sessionId, only sessionId is forwarded to Stripe's redirectToCheckout. Stripe.js rejects the call if any other field (successUrl, cancelUrl, locale, ...) is passed alongside sessionId, which would prevent Checkout from loading. Configure those options when you create the Checkout Session server-side instead.
• onSuccess (?Function) - Called upon success of the checkout session with { ...props, checkoutSessionId: 'CHECKOUT_SESSION_ID' }
• onCancel (?Function) - Called upon cancellation of the checkout session with { ...props }
• onLoadingComplete (?Function) - Called when the Stripe checkout session webpage loads successfully.
• options (?Object) - custom options to display content in the webview
• htmlContentLoading (String) - Html string to display a loading indication. - default: <h1 id="sc-loading">Loading...</h1> - note: The loading item is set on the element with id='sc-loading'
• htmlContentError (String) - Html string to display stripe errors. - default: `

- note: The error is set on the element with id='sc-error-message' -htmlContentHead(String) - Html string to inject in head. - default: '' -webViewProps(?Object) - WebView Component props, spread on the WebView Component. -renderOnComplete` (?(props) => React$Node) - Optional rendering function returning a component to display upon checkout completion. note: You don't need this if your onSuccess and onCancel functions navigate away from the component.

A note on locale

• Client-only flow (lineItems/items): pass locale directly in checkoutSessionInput - it is forwarded to redirectToCheckout.
• Server-side Checkout Session flow (sessionId): the displayed language is determined by the locale you set when creating the Checkout Session server-side - this is the authoritative source. Stripe.js does not accept locale alongside sessionId, so it is not forwarded to redirectToCheckout (doing so would prevent Checkout from loading). As a convenience, a locale passed in checkoutSessionInput is still applied as a client-side hint via the Stripe.js constructor (Stripe(key, { locale })), which localizes error strings.

Avoiding a 404 on success / cancel

• The library intercepts the successUrl/cancelUrl redirect via the WebView's onShouldStartLoadWithRequest and prevents the WebView from navigating to it, then calls onSuccess/onCancel. This means your successUrl/cancelUrl can be a placeholder that does not resolve to a real page - the WebView will never render its (potentially 404) content. Just make sure the URLs follow the structure above.

Apple Pay and Google Pay

• This library uses react-native-webview under the hood to render the Stripe Checkout webpage. To get Apple Pay and Google Pay to work we need to pass the context to the browser, here's how to get it working:
• What causes the issue is an injected script by default on webview start named html5HistoryAPIShimSource How to fix (Note that the fix doesn't fully work on expo, but workarounds can be found in the issue thread):
  • Comment this line in /node_modules/react-native-webview/apple/RNCWebView.m like shown below (in v10.9.2 line number is 1270.) WKUserScript *script = [[WKUserScript alloc] initWithSource:html5HistoryAPIShimSource injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:YES]; // [wkWebViewConfig.userContentController addUserScript:script]; // this line that inject "html5HistoryAPIShimSource" on start
