How to Install Google Pay in Shopify Checkout Kit

Based on the latest Shopify documentation and changelog, Google Pay is now available as an express checkout option in Checkout Kit as of June 26, 2025. Checkout Kit now supports Google Pay in checkout, giving your customers another way to complete their purchases through your mobile app. Google Pay works with your existing checkout customizations, and is available alongside other express checkout options.

Here’s a comprehensive guide on how to install and enable this update:

Prerequisites

Before installing Google Pay in Checkout Kit, ensure you meet these requirements:

1. Payment Gateway Setup: You need to use a credit card payment provider that lists Google Pay as an available payment method. You can use Shopify Payments with Google Pay in all regions except France, or you can search for Google Pay as a payment method in the list of third-party payment providers in Settings > Payments.
2. Store Configuration: Your Shopify store must have Google Pay enabled as a payment method in your admin settings.

Installation Steps

For Android Apps

Step 1: Update to Latest Version Update your Checkout Kit dependency to the latest version that includes Google Pay support:

   <artifactId>checkout-sheet-kit</artifactId>
   <version>3.3.0</version>
</dependency>

import com.shopify.checkoutsheetkit.ShopifyCheckoutSheetKit

fun presentCheckout() {
    val checkoutUrl = cart.checkoutUrl
    ShopifyCheckoutSheetKit.present(checkoutUrl, context, checkoutEventProcessor)
}

For iOS Apps

Step 1: Update Package Dependency

Using Swift Package Manager:

dependencies: [
  .package(url: "https://github.com/Shopify/checkout-sheet-kit-swift", from: "3")
]

Or via Xcode:

1. Open your Xcode project
2. Navigate to File > Add Package Dependencies…
3. Enter https://github.com/Shopify/checkout-sheet-kit-swift
4. Update to the latest version (3.x)

Step 2: Import and Implement

import ShopifyCheckoutSheetKit

class MyViewController: UIViewController {
  func presentCheckout() {
    let checkoutURL: URL = // obtained from buyer's cart
    ShopifyCheckoutSheetKit.present(checkout: checkoutURL, from: self, delegate: self)
  }
}

For React Native Apps

Step 1: Update Package

Enabling Google Pay in Your Store

Step 1: Configure Payment Settings

1. Go to your Shopify admin panel
