S2S UPI Intent Flow

Customers need not enter VPA or phone numbers as these details are prefilled and submitted along with the other payment details. While making the payment, customers select the UPI PSP app on your UI. The app is launched automatically on their mobile devices where the payment is completed.

Best Practices

If you have a significant amount of payment traffic coming from the Mobile Site, then it is advisable to use the Google Pay Intent flow available for the mSite:

Do not change Intent URL

Do not make changes to the intent URL shared by Razorpay as part of the API response. Making changes to the intent URL can lead to payment failure.

Host UPI apps

It is recommended to host the UPI apps on your page/app instead of just hosting the Intent URI where the apps are shown by the native Android drawer. This improves conversion. 3. Rank UPI Apps by Success Rate Show the UPI PSP apps in the order of their success rate. 4. Mobile site If you have higher traffic via mobile site, then make sure you provide the option of UPI intent payment to your users using our m-site integration. This will help you achieve better success rates. 5. Gpay SDK If your UPI transaction volumes are high, you can also explore integrating Gpay SDK. This provides a better user experience and about a 3-5% improvement in success rate.
