Google Pay Now Fully Supported Inside Android WebView: A Game-Changer for Mobile Payments

In the fast-evolving world of mobile apps, offering seamless and secure payment options is key to delivering great user experiences. Android developers embedding web checkout processes inside their apps through WebView now have a powerful new tool at their disposal. Google has announced official support for Google Pay within Android WebView starting with version 137. This update leverages the Payment Request API, enabling native payment apps to launch directly from the embedded web content. The result is a smooth, integrated payment flow that uses device-stored tokens, making checkout faster and more secure for users.

This new feature is available with Google Play Services 25.18.30 and above. When triggered inside a WebView, Google Pay now brings up the native payment sheet, ensuring users can complete transactions just as easily as they would in a standalone app or mobile browser. However, developers need to take a few straightforward steps to enable this functionality: updating build dependencies to androidx.webkit:webkit version 1.14.0-rc01 or later, adding specific intent queries in their AndroidManifest.xml, and enabling the Payment Request API on their WebView instance. The process supports both Kotlin (including Compose) and Java implementations, making integration accessible for all Android developers.

By embracing this update, app creators can elevate their checkout process without redesigning their entire payment flow, reducing friction for customers and increasing conversion rates. To move into production, developers must request access via the Pay & Wallet console. Google also encourages developers to reach out for support through the developer community on Discord or by tagging @GooglePayDevs on X.

With this update, Android developers gain a robust, easy-to-implement solution for embedding Google Pay in web checkouts inside apps. This not only brings consistency to the payment experience across platforms but also taps into the growing user preference for digital wallets over traditional payment methods. The Payment Request API serves as the backbone, allowing web content to invoke native payment UIs securely and efficiently, even when displayed inside an app’s WebView.

This integration removes the old friction points such as redirecting users out of the app to complete payments or relying on cumbersome form-filling. Instead, payments become a native, streamlined experience with access to saved payment methods, device tokens, and biometric authentication where supported. The move signals Google’s broader strategy to unify payment experiences across browsers, apps, and devices while maintaining user security and privacy.

Developers, however, should pay attention to the details: enabling Payment Request API is off by default and requires explicit configuration. Ensuring correct manifest declarations and dependencies will be crucial to avoid issues. Also, requesting production access early will prevent deployment delays. The provided Kotlin and Java code snippets demonstrate how simple these changes can be, even for teams unfamiliar with the WebView API’s intricacies.

What Undercode Say:

Google’s decision to enable Google Pay inside Android WebView marks a significant advancement for mobile commerce. It bridges the gap between web-based checkout flows and native payment experiences, which has long been a challenge for hybrid apps or apps embedding third-party web content. The Payment Request API is a well-established web standard designed to facilitate quick, secure payments; enabling it inside WebView expands its reach dramatically.

This update is a win for developers aiming to reduce drop-offs during payment, which is a critical conversion bottleneck. Since the native payment sheet leverages device tokens and user authentication, it naturally offers enhanced security and user trust. Additionally, integrating Google Pay in WebView keeps users within the app environment, improving retention and the overall user journey.

The requirement to add intent filters and update dependencies could be a slight hurdle, but Google’s clear documentation and sample code mitigate this. It will be interesting to observe how quickly adoption happens in real-world apps, particularly in industries like retail, food delivery, or ride-sharing, where embedded web payments are common.

Moreover, Google’s push for developer engagement via Discord and Twitter suggests an ongoing commitment to refining this experience. Future updates might include broader payment method support or enhancements to the Payment Request API’s capabilities in WebView. For now, this feature aligns perfectly with trends favoring digital wallets and contactless payments worldwide.

The move also indicates a subtle shift in how Google envisions app development: embracing hybrid models where web content and native code coexist smoothly, rather than forcing a fully native or purely web approach. This hybrid flexibility can speed development cycles and bring more robust features to market faster.

However, developers must remain vigilant about security best practices. While Google Pay offers secure tokenization, the surrounding app and WebView configurations must be kept up to date to prevent vulnerabilities. Ensuring that WebView settings like JavaScript enablement are handled carefully is essential.

Overall, this update signals a maturing ecosystem where mobile payments become frictionless regardless of whether users are in a browser, a native app, or a hybrid environment. It reflects Google’s broader vision of seamless, secure, and user-friendly digital commerce.

Fact Checker Results:

Google Pay support inside Android WebView begins with WebView version 137 and Google Play Services 25.18.30. ✅
Payment Request API must be explicitly enabled in WebView settings for Google Pay to function. ✅
Developers need to update dependencies and add specific intent queries in the AndroidManifest.xml. ✅

Prediction:

As this integration becomes more widely adopted, expect a surge in apps offering streamlined, native-like payment experiences without building fully native checkout flows. This will likely accelerate the shift toward digital wallets in mobile commerce, boosting conversion rates and user satisfaction. Over time, Google may expand support to other payment methods through the Payment Request API in WebView, creating a versatile, unified payment ecosystem across Android apps. This development could also encourage other platform providers to follow suit, standardizing embedded web payments industry-wide.
