The Google Pay API enables fast, simple checkout within your app, and gives you convenient access to hundreds of millions of cards saved to Google Accounts worldwide.
How it works
When a user taps the Google Pay payment button, they see a payment sheet that displays the payment methods saved to their Google Account, as well as optional fields such as a shipping address field. Users can quickly select a payment method, add an optional shipping address, or add new information.
The payment flow is as follows:
- The user taps the Google Pay payment button and sees a payment sheet with a list of supported payment methods.
- The user selects a payment method and Google Pay securely returns a payment token for that method to your app.
- Your app submits the payment token, along with details about the purchase, to its backend.
- To execute the payment, the backend processes the purchase and sends the payment token to the payment service provider.
