How to Confirm a Stripe PaymentIntent in Your Expo React-Native Application

In today's digital landscape, ensuring seamless payment processing is crucial for businesses. If you’re using Stripe for handling payments in your Expo React-Native application, you might be facing challenges when shifting from using expo-payments-stripe to the PaymentIntent API. This guide will walk you through the steps needed to confirm a PaymentIntent effectively in your Expo app.

The Problem: Transitioning to PaymentIntents

Previously, the payment processing in your application was straightforward, utilizing methods like paymentRequestWithCardFormAsync. With the new implementation using PaymentIntent, however, you may find yourself needing a PaymentMethodId instead of a simple token. The challenge arises when:

You don’t have the client’s payment method initially.

The first PaymentIntent needs to be confirmed on the client-side.

There is no dedicated library for Expo React-Native that can facilitate this process.

This scenario can be perplexing, especially if you had managed to do this easily with a web client using Stripe Elements.

The Solution: Leverage a WebView

Since there is no direct library available for this functionality in Expo, the best workaround is to integrate a WebView to utilize the Stripe.js library effectively. Below, we break down how you can achieve this.

Step 1: Setting Up the WebView

You will need to create a WebView component in your React-Native application that loads an HTML page where Stripe Elements can be used. Here’s an example of how to set it up:

Step 2: Rendering HTML for Stripe Elements

Here's how to structure the HTML that will be displayed in the WebView. This code integrates Stripe Elements along with error handling and subscription logic.

Step 3: Handle the Payment Process

After setting up the WebView and the HTML, handle payment processing in your JavaScript inside the HTML. Use the Stripe library to create a PaymentMethod and confirm the PaymentIntent, then communicate the result back to your React Native app.

Benefits of This Approach

Cross-Platform Compatibility: Utilizing a WebView allows you to access web-specific libraries and functionalities.

Flexibility: You can easily modify the HTML and JavaScript to suit your specific needs, including styling and handling user feedback.

Effective Communication: By using window.ReactNativeWebView.postMessage, you can communicate seamlessly between your React Native application and the WebView.

Conclusion

Transitioning your Expo React-Native application to support Stripe's PaymentIntent through a WebView may seem daunting, but with the right setup, it can lead to an efficient payment process. This method not only simplifies client-side payment confirmations but also opens up new possibilities for handling subscriptions directly within your app.

Implement this approach to streamline your payment functionalities using Stripe, enhancing user experience and operational efficiency.
