The Starbucks app for Android has been updated this morning and it brings the ability to do a one time adding of funds to your account from Google Pay. The update is version 4.11.1 for those keeping score at home and should be out to everyone who has the app installed by now.
Once you have updated, you can go to the FAB (Floating Action Button) which has your current account balance and tap it and then go to the Add money option. There you will see your credit card information you normally use to top up your card but if you use change the Payment type, you will see that Google Pay is an option.
When you use the feature, your Starbucks account will have funds added from whatever your default payment mode is in Google Pay.
While you can setup Google Pay as a one time funds addition in the app, you can’t set it up as your reoccurring option for automatic reloading of your account. You still have to configure a debit or credit card for that feature.
The Starbucks app is free to download from the Play Store if you don’t have it already.
