Integrate Google Pay for in-app payments

AI-generated Key Takeaways

• Follow the Android guide and prepend gpay:// to the URI to generate the iOS intent for Google Pay integration.

• The URI structure for iOS and Android intents is almost identical, with the iOS version requiring gpay:// at the beginning.

• After completing a payment, iOS users need to manually switch back to the merchant app, which is a current limitation of the collect/intent flows.

• Refer to the NPCI UPI Linking Specification for detailed information about request and response argument specifications.

Follow the Android guide for generating the URI for iOS intent and integrating Google Pay with your app.

Important: The URI for iOS intent is similar to that of Android intent. The only difference is that you need to add gpay:// at the beginning of the URI. This should launch Google Pay on iOS.

For more information regarding the request and response argument specifications, see NPCI UPI Linking Specification.

Note: Currently, iOS does not support switching back to the merchant app post payment. The user needs to manually toggle back to the merchant app once the payment is completed. This is in line with the current status quo on collect/intent flows.
