Stripe Tutorial

Integrating Stripe Payment Module from One React Native App to Another​

This tutorial outlines the steps to integrate the Stripe payment module from an existing React Native app into another app.

Step 1: Install Required Dependencies​

Make sure you have the necessary Stripe dependencies installed in your target app. Run the following command:

npm install @stripe/stripe-react-native

Step 2: Copy Payment Logic

  1. Copy Payment API: – Copy the payment processing logic from src/Core/payments/api/paymentProcessor/paymentRequestClient.js to your target app. This includes functions like chargeStripeCustomer, setupStripe, etc.

  2. Copy Hooks:

    – Copy the usePaymentRequest and usePaymentSheetManager hooks from src/Core/payments/usePaymentRequest.js and src/Core/payments/usePaymentSheetManager.js respectively.

  3. Copy Redux Actions:

    – If your payment module uses Redux, copy the relevant actions and reducers from src/Core/payments/redux/checkout.js to your target app.

Step 3: Update Configuration​

  1. Stripe Configuration:

    – Ensure that your target app has the necessary Stripe configuration. This includes the publishable key and any other required settings. Set this up in your app’s configuration file.

  2. Google Services:

    – If your app uses Firebase, ensure that the googleServicesFile is correctly set up in your app.json or AndroidManifest.xml.

Step 4: Implement Payment Logic​

  1. Create Payment Form:

    – In your target app, create a payment form component where users can enter their payment details. Use the StripeProvider to wrap your app or the specific component where you handle payments.


  import React from ‘react’;

  import { StripeProvider } from ‘@stripe/stripe-react-native’;

  import App from ‘./App’; // Your main app component

  const AppWrapper = () => {

    return (

      <StripeProvider

        publishableKey=”your-publishable-key”

        merchantIdentifier=”merchant.identifier” // Optional

      >

        <App />

      </StripeProvider>

    );

  };

  export default AppWrapper;

  1. Use Payment Hooks:

    – Use the usePaymentRequest and usePaymentSheetManager hooks in your payment form component to handle payment requests and manage the payment sheet.


 import React, { useState } from ‘react’;

 import { Button, View } from ‘react-native’;

 import usePaymentRequest from ‘./path/to/usePaymentRequest’;

 const PaymentForm = () => {

   const appConfig = {}; // Your app configuration

   const { chargeStripeCustomer, setupStripe } = usePaymentRequest(appConfig);

   const [loading, setLoading] = useState(false);

   const handlePayment = async () => {

     setLoading(true);

     const email = ‘[email protected]’; // Get this from your form

     const setupResponse = await setupStripe(email);

     

     if (setupResponse.success) {

       const chargeResponse = await chargeStripeCustomer({

         amount: 1000, // Amount in cents

         currency: ‘usd’,

         token: setupResponse.data.token, // Get token from your form

       });

       // Handle charge response

     }

     setLoading(false);

   };

   return (

     <View>

       <Button title=”Pay” onPress={handlePayment} disabled={loading} />

     </View>

   );

 };

 export default PaymentForm;

Step 5: Test the Integration​

  1. Run Your App:

    – Start your target app and navigate to the payment form.

  2. Test Payments:

    – Use test card numbers provided by Stripe to test the payment flow.

Step 6: Handle Errors and Edge Cases​

Make sure to handle errors gracefully, such as network issues or payment failures. Use alerts or notifications to inform users of any issues.
