Easily connect Google Pay with your preferred payment processor
Adding Google Pay as a payment method to your website or Android application provides a secure and fast checkout option for your users. To enable Google Pay, you will first need a Payment Service Provider (PSP). For the integration this means understanding how your payments processing stack works with Google Pay APIs.
End-to-end PSP samples
A recent study by 451 Research showed that for merchants with over 50% of sales occurring online, 69% of merchants used multiple PSPs. With these new samples, we demonstrate how you can implement an entirely consistent interface to multiple PSPs, streamlining your codebase while also providing more flexibility for the future.
Lastly, we've also added support to both the Web and Android Google Pay sample applications, making it easy to demonstrate the new PSP samples. Simply run the PSP samples project, and configure the Web or Android samples to send their cart information and Google Pay token to the PSP samples app, which will then send the relevant data to the PSP's API and return the PSP's response back.
To start with, we've included support for 6 popular PSPs: Adyen, Braintree, Checkout.com, Cybersource, Square, and Stripe. But that's just the beginning. If you're involved with a PSP that isn't yet included, we've made adding new PSPs to the open source project as simple as possible. Just head on over to the GitHub repository which contains instructions on contributing your preferred PSP to the project.
Launching Google Pay for your website
When you’ve completed your testing, submit your website integration in the Google Pay Business Console. You will need to provide your website’s URL and screenshots to complete the submission.
Summing it up
Integrating Google Pay into your website is a great way to increase conversions and to improve the purchasing experience for your customers, and with these new open source samples, the process is even easier.
