Google has announced new dynamic callback support for Google Pay on Android, allowing developers to create smarter and more interactive checkout experiences inside mobile apps. The update was shared through the official Google Developers Blog.
The new feature enables Android apps to update checkout information in real time during the payment flow using callbacks. Developers can now dynamically adjust:
Shipping costs
Taxes
Delivery options
Transaction totals
Error messages
based on user selections inside the Google Pay sheet.
Google says this helps merchants build faster and more flexible checkout experiences while reducing friction during payments. The company recently updated Google Pay Android documentation to officially support Dynamic Price Updates through callbacks.
The announcement builds on Google’s broader effort to modernize mobile checkout experiences on Android. Recent updates have included dynamic Google Pay buttons, Material 3 UI improvements, Jetpack Compose support, and faster in-app payment integrations.
According to Google, developers can integrate the feature using updated Google Pay request and response objects with callback intents for shipping address and shipping option changes.
The feature is particularly useful for e-commerce apps that need real-time pricing adjustments during checkout flows.
