Google Pay
Google Pay allows customers to make payments in your app or website using any credit or debit card saved to their Google Account, including those from Google Play, YouTube, Chrome, or an Android device. Use the Google Pay API to request any credit or debit card stored in your customer’s Google account.
Google Pay is fully compatible with Stripe’s products and features (for example, subscriptions), allowing you to use it in place of a traditional payment form whenever possible. Use it to accept payments for physical goods, donations, subscriptions, and more.
Accept a payment using Google Pay in your Android app
GooglePayLauncher
, part of the Stripe Android SDK, is the fastest and easiest way to start accepting Google Pay in your Android apps.
Set up your integration
To use Google Pay, first enable the Google Pay API by adding the following to the <application>
tag of your AndroidManifest.xml:
<application> ... <meta-data android:name="com.google.android.gms.wallet.api.enabled" android:value="true" /> </application>
This guide assumes you’re using the latest version of the Stripe Android SDK.
dependencies { implementation 'com.stripe:stripe-android:20.20.0' }
For more details, see Google Pay’s Set up Google Pay API for Android.
Instantiate GooglePayLauncher
Next, create an instance of GooglePayLauncher in your Activity
or Fragment
. This must be done in Activity#onCreate()
.
GooglePayLauncher.Config
exposes both required and optional properties that configure GooglePayLauncher
. See GooglePayLauncher.Config
for more details on the configuration options.
After instantiating GooglePayLauncher
, the GooglePayLauncher.ReadyCallback
instance is called with a flag indicating whether Google Pay is available and ready to use. This flag can be used to update your UI to indicate to your customer that Google Pay is ready to be used.
Launch GooglePayLauncher
After Google Pay is available and your app has obtained a PaymentIntent
or SetupIntent
client secret, launch GooglePayLauncher
using the appropriate method. When confirming a PaymentIntent
, use GooglePayLauncher#presentForPaymentIntent(clientSecret)
. When confirming a SetupIntent
, use GooglePayLauncher#presentForSetupIntent(clientSecret)
.
Handle the result
Finally, implement GooglePayLauncher.ResultCallback
to handle the result of the GooglePayLauncher
operation.
The result can be GooglePayLauncher.Result.Completed
, GooglePayLauncher.Result.Canceled
, or GooglePayLauncher.Result.Failed
.
Going live with Google Pay
Follow Google’s instructions to request production access for your app. Choose the integration type Gateway when prompted, and provide screenshots of your app for review.
After your app has been approved, test your integration in production by setting the environment to GooglePayEnvironment.Production
, and launching Google Pay from a signed, release build of your app. Remember to use your live mode API keys. You can use a PaymentIntent
with capture_method
= manual
to process a transaction without capturing the payment.
Creating a PaymentMethod
If you confirm your payment on your server, you can use GooglePayPaymentMethodLauncher
to only collect a PaymentMethod
instead of confirm payment.
